In the ever-evolving landscape of technology, the development of robust and reliable software systems is crucial for businesses and organizations to stay competitive and meet the needs of their users. To achieve this, a structured approach known as the Software System Development Life Cycle (SDLC) is employed. The SDLC provides a systematic framework for planning, designing, building, testing, deploying, and maintaining software systems. In this article, we delve into the various phases of the SDLC and their significance in the development process.
The classical waterfall model is a sequential and linear software development methodology. It is one of the earliest and most traditional approaches to software development, and it follows a step-by-step process in which progress is seen as flowing steadily downwards (like a waterfall) through several phases. Each phase must be completed before the next one begins, and there is minimal overlapping or iteration between the phases.
Iterative development is a software development methodology where the process is broken down into smaller cycles, called iterations, and each iteration involves the repetition of a subset of the development process. In iterative development, the project is divided into small parts, and each part goes through the whole software development life cycle (SDLC) – including planning, requirements, design, coding, testing, and deployment. The major characteristic of iterative development is that it is incremental and allows for changes to be made as the project progresses.

Iterative Development Model is a software development approach that involves the continuous testing, evaluation, and improvement of a product throughout its development lifecycle. Unlike traditional approaches that follow a linear path, iterative models allow for more flexibility and room for change.
In this model, the development process is broken down into small, manageable iterations, each of which produces a working product increment. This allows for continuous feedback and evaluation from stakeholders, which can be used to make improvements and adjustments as needed.
Iterative development models are often used in agile software development methodologies, as they emphasize collaboration, flexibility, and adaptability. By embracing change and focusing on delivering working products that meet the changing needs of customers, iterative development models can help organizations improve their software development processes and deliver better products to market.
Key features of iterative development include:
continuous testing, frequent feedback, and incremental changes. In an iterative development process, the development team works in short cycles, with each cycle aimed at delivering a functional piece of the product. This allows for faster identification of any errors or issues, and for adjustments to be made in a timely manner.
Another benefit of iterative development is that it promotes collaboration and communication between team members. Because each cycle is focused on a specific goal, team members can work closely together to achieve that goal. This helps to ensure that everyone is on the same page and that there are no misunderstandings or miscommunications.
Iterative development also allows for greater flexibility in the development process. Because each cycle is relatively short, changes can be made quickly and easily. This means that the development team can adapt to changing requirements or new information without needing to start the entire development process from scratch.
Overall, iterative development is a highly effective approach to software development that promotes collaboration, flexibility, and efficiency. By breaking the development process down into smaller, more manageable cycles, the development team can deliver a high-quality product in a timely manner.
Incremental Development: The project is developed and delivered in smaller, manageable parts or increments. Each increment represents a portion of the final product, and new features or improvements are added in subsequent iterations.
Incremental development is a popular approach in software development, where the project is broken down into smaller parts or increments. This allows developers to work on manageable portions of the project, and deliver working software in a more frequent and predictable manner. Each increment represents a portion of the final product, and new features or improvements are added in subsequent iterations. This approach allows for more flexibility in adapting to changing requirements or feedback from stakeholders, and can also help to mitigate risks by identifying issues early on in the development process. Incremental development is often used in Agile software development methodologies, such as Scrum or Kanban, where teams work in short iterations and deliver working software at the end of each iteration.
Feedback and Adaptation: Iterative development encourages regular feedback from users, stakeholders, and team members. This feedback is used to refine and adapt the product in subsequent iterations. This allows for flexibility in responding to changing requirements.
The feedback loop is an essential part of iterative development. It helps to ensure that the product meets the needs of the users and stakeholders. By gathering feedback and making changes in subsequent iterations, the team can adapt the product to changing requirements and improve its overall quality. This approach allows for flexibility, enabling the team to respond quickly to new challenges and opportunities. Ultimately, iterative development helps to create a product that is both useful and effective, improving the user experience and maximizing value for stakeholders.
Repetition of Activities: Each iteration goes through the entire SDLC, including planning, analysis, design, implementation, testing, and deployment. This repetition allows for continuous improvement and refinement.
Repeating activities is a crucial part of software development. It allows for the identification of errors and faults early in the process, reducing the likelihood of major issues later on. Repetition also enables the team to learn from previous iterations and make improvements to the process, resulting in a more efficient and effective SDLC. This approach is particularly useful in Agile methodologies, where constant iteration and feedback are key to success. By embracing repetition, software development teams can ensure that their products are of the highest quality, meeting the needs of users and stakeholders alike.
Flexibility and Adaptability: Iterative development is well-suited for projects where requirements are not well-defined initially or are expected to change. It provides the flexibility to accommodate changing needs and priorities.
Iterative development is a process that involves breaking down a large project into smaller, more manageable pieces. Each piece is developed and tested individually, then combined with the other pieces to create the final product. This approach allows for frequent feedback and adjustments, which can help ensure that the final product meets the needs of its users.
Flexibility and adaptability are key benefits of this approach. The iterative development process allows for changes to be made along the way, which can help ensure that the final product meets the changing needs of its users. This can be especially useful in projects where the requirements are not clear or are expected to change over time. Overall, iterative development is a powerful tool for building high-quality software that meets the needs of its users. By providing flexibility and adaptability, it allows teams to work more effectively and deliver better results.
By breaking down the development process into smaller iterations, potential risks can be identified and addressed before they become major issues. This allows for adjustments to be made in a timely and efficient manner, reducing the likelihood of delays and cost overruns. Additionally, the iterative approach allows for continuous feedback from stakeholders and end-users, ensuring that the final product meets their needs and expectations. As a result, risk management becomes an ongoing process throughout the development lifecycle, rather than a one-time event. Ultimately, iterative development can improve project outcomes and increase customer satisfaction.
Risk Management: Iterative development helps manage risks by identifying and addressing issues early in the development process. This is particularly important in complex projects where uncertainties are high.
Common iterative development methodologies include the Rational Unified Process (RUP), Scrum, and the Agile development approach. These methodologies may have their own specific practices and principles, but they all share the fundamental concept of iterative and incremental development.
The Waterfall Model is a sequential and linear approach to software development that is part of the Software Development Life Cycle (SDLC). The SDLC is a framework that defines the process of software development from the initial planning stages to deployment and maintenance. The Waterfall Model is one of the classic models within the SDLC.
In software, “API” stands for “Application Programming Interface.” An API provides a set of rules and protocols that allow different software entities to communicate with each other. It specifies the methods and data formats that software components should use when requesting and exchanging information.
API
Here are some key points to understand about APIs:
Abstraction: An API abstracts the underlying implementation and only exposes objects or actions the developer needs. This allows the programmer to interact with a system or platform without knowing the internal details of that system.
Types of APIs:
Web APIs: These allow interaction over the web, typically using HTTP/HTTPS. Examples include REST, SOAP, and GraphQL APIs.
Library & Framework APIs: These provide pre-defined functions and routines to perform specific tasks, like the JavaAPI.
Operating System APIs: These allow applications to make requests to the operating system, such as file operations or network requests.
Database APIs: These allow communication between an application and a database, such as JDBC for Java.
Benefits:
Interoperability: APIs enable different software systems, which may be built using different technologies, to work together.
Efficiency: Developers can leverage pre-existing components and services instead of building everything from scratch.
Standardization: By defining a standard interface, it’s easier to ensure that different software components interact correctly.
API Endpoints: In the context of web APIs, an endpoint refers to a specific URL where an API can be accessed and perform some action (e.g., retrieve, create, update, or delete data).
Security: Proper care needs to be taken when developing and consuming APIs to ensure that sensitive data is protected, and malicious attacks are prevented. Common practices include using tokens, OAuth, and rate limiting.
Versioning: As software evolves, its API might need changes that could break existing clients. To handle this, developers often use versioning to ensure backward compatibility.
In the modern world of software, APIs are instrumental in building scalable and flexible systems, enabling integrations across diverse platforms and technologies.

Requirements Gathering and Analysis
The first phase of the Waterfall model is requirements gathering and analysis. This crucial step involves engaging stakeholders, understanding their needs, and defining project requirements. Through interviews, surveys, and workshops, project managers collect information and document it in a comprehensive requirement specification document. This document acts as a blueprint for the entire project, ensuring that everyone involved has a clear understanding of what needs to be achieved.
During the analysis phase, project managers analyze the gathered requirements, identifying potential risks, constraints, and dependencies. This careful analysis helps in the identification of project milestones and facilitates effective resource allocation. By thoroughly understanding the project requirements and potential challenges, project teams can plan and allocate resources efficiently, setting the stage for successful project delivery.
Design and Planning
Once the requirements are gathered and analyzed, the next phase of the Waterfall model is design and planning. This phase focuses on translating the requirements into a detailed design that outlines the project’s architecture, modules, and components. Designers and architects collaborate to create a blueprint that serves as a guide for development and implementation.
During the planning stage, project managers create a detailed project plan, outlining the timeline, resource allocation, and dependencies. This plan serves as a roadmap for the project team, ensuring that everyone is aligned and aware of their roles and responsibilities. By investing time in meticulous design and planning, the Waterfall model enables teams to identify potential bottlenecks and address them proactively, minimizing the risk of delays during the later stages of the project.
Implementation and Development
With the requirements gathered, analyzed, and the design in place, it’s time for implementation and development. This phase involves the actual coding and development of the project, bringing the design to life. Developers work closely with the design team to ensure that the project is implemented according to the specifications outlined in the design phase.
The Waterfall model promotes a structured approach to development, where each module is built sequentially, following the predetermined project plan. This sequential development process allows for better control and monitoring, ensuring that each module is thoroughly tested before moving on to the next. By breaking down the project into manageable components, the Waterfall model promotes efficiency and minimizes the risk of errors or rework.
Testing and Quality Assurance
Once the implementation and development phase is complete, it’s time for testing and quality assurance. This critical phase ensures that the project meets the defined requirements and functions as intended. Testers meticulously examine each module, conducting various tests to identify any defects or inconsistencies.
The Waterfall model emphasizes thorough testing at each stage, with dedicated testers focusing on different aspects, such as functionality, performance, security, and user experience. By conducting comprehensive testing, project teams can identify and address any issues early on, minimizing the risk of costly rework or project delays. The Waterfall model’s sequential flow allows for an organized and systematic approach to testing, ensuring that all modules are thoroughly vetted before proceeding to the next phase.
Deployment and Delivery
The final phase of the Waterfall model is deployment and delivery. Once the project has been thoroughly tested and meets the defined requirements, it is ready for deployment. Project teams work together to deploy the project in the production environment, ensuring a smooth transition from development to the live system.
During the deployment phase, project teams provide support and training to end-users, ensuring a seamless adoption of the new system. This phase also involves conducting user acceptance testing, where end-users validate the project’s functionality and provide feedback. By involving end-users in the testing and deployment process, the Waterfall model promotes user satisfaction and reduces the risk of post-deployment issues.
Advantages of the Waterfall Model
The Waterfall model offers several advantages that contribute to seamless project delivery. Let’s explore some of the key benefits of adopting this methodology:
Clear Project Roadmap
One of the primary advantages of the Waterfall model is its clear project roadmap. The linear flow of the model provides a well-defined path from start to finish, ensuring that project teams have a clear understanding of the project’s scope, requirements, and deliverables. This clear project roadmap minimizes the risk of scope creep and keeps the project on track.
Predictable Outcomes
Another advantage of the Waterfall model is predictable outcomes. Since each phase is completed before moving on to the next, project teams can accurately estimate timelines and resource requirements. This predictability allows for better planning and resource allocation, reducing the risk of delays and budget overruns.
Efficient Collaboration
The Waterfall model promotes efficient collaboration among project teams. By breaking down the project into distinct phases, teams can work in parallel, focusing on their specific tasks and responsibilities.

This thorough documentation serves as a reference point and helps in knowledge transfer, ensuring that project knowledge is captured and preserved.
Limitations of the Waterfall Model
While the Waterfall model offers numerous advantages, it is important to acknowledge its limitations. Let’s explore some of the common challenges associated with this methodology:
Lack of Flexibility
One of the main limitations of the Waterfall model is its lack of flexibility. Once a phase is complete, it is difficult to revisit and make changes without impacting the subsequent phases. This lack of flexibility can be problematic when requirements change or new information is discovered during the project’s lifecycle.
Limited Client Involvement
The Waterfall model often limits client involvement until the later stages of the project. Since the project follows a sequential flow, clients may not have a clear understanding of the project’s progress until the final deliverable is presented. This limited client involvement can lead to misalignment and potential rework if the client’s expectations are not met.
Higher Risk of Scope Creep
Due to the sequential nature of the Waterfall model, there is a higher risk of scope creep. If project requirements change or evolve during the implementation phase, it can be challenging to accommodate these changes without impacting the project timeline and budget. This can lead to additional costs and delays.
Best practices for implementing the Waterfall Model
To maximize the benefits of the Waterfall model and mitigate its limitations, consider the following best practices:
Thorough Requirements Gathering
Invest time and effort in gathering and analyzing project requirements. Engage stakeholders early on and ensure a clear understanding of their needs and expectations. Thorough requirements gathering sets the foundation for a successful project.

1. What is waterfall model in software engineering ?
In software engineering, a waterfall model is a conceptual model for developing, testing, and deploying computer software. The model starts with defining the problem or requirement that the software is to address, then creating a high-level design of the system. Next, an implementation plan is created based on the design and specified using specific programming codes. Finally, units of testing are conducted to verify that the program works as it should. The entire process is repeated throughout the software development life cycle to ensure that all subsystems work as planned and that any bugs are fixed before launch into the production environment.
In software engineering, a waterfall model is a model of software development (also known as product development). It is a sequential, staged process in which each phase of the process is completed before moving on to the next. The waterfall model is most commonly used for large software projects, where it provides a well-defined and structured approach to writing, testing, and deploying releases.
The four major phases of the waterfall model are requirements gathering, design, development, testing, and maintenance. The requirement gathering phase involves getting all the relevant information about the project. This includes understanding what is being built and understanding the user’s needs. The design phase creates the overall structure of the software and determines how it will be implemented. During this phase, developers may create user interfaces or codebase components. Finally, development takes place during which the actual code is written. Testing ensures that the software functions as intended and is error-free. Once it meets these standards, it is released to users for maintenance. Depending on the size and complexity of the project, this might involve fixing bugs or adding new features
In software engineering, waterfall model is a development process that starts with requirements gathering and progresses through design, testing, and deployment. The goal is to achieve software quality levels before deploying the code. The process is divided into five phases: requirements gathering, design, coding, testing, and deployment.
2. Requirements Gathering / Analysis
Requirements gathering occurs during the early stages of project when stakeholders are gathered together to discuss their needs and goals for the project. This is where requirements are clarified, refined, and may be changed. Requirements should be concise but detailed enough to allow for proper planning.
3. Design
Design occurs after the requirements have been collected and a plan has been created for the project. It includes developing a low-level specification of what will be implemented. Design also determines how the code will be coded and how it will be tested.
4. Coding
Coding takes place once the design has been completed and code is written in an appropriate language for the project. It involves creating individual modules that work together to implement the design specifications. Code should be well documented so future developers can understand it easily.
5. Testing
Testing begins once the code has been written and goes through various levels of testing to make sure it meets all the requirements set forth in the design phase. Once tests have been completed, it’s ready for deployment onto a real or simulated environment.
6. Deployment
Deployment begins by pushing the new code to a staging area so that it can be evaluated before being released into production settings. If all goes according to plan, finally production environments can be updated with the new code.
REST API is a term that describes how data is transferred between different applications over the internet. REST APIs are often used in mobile apps, websites, and other software programs.
What is REST API
This tutorial will show you how to build a RESTful web service using PHP and MySQL.
REST APIs are designed to work with HTTP requests and responses. They use standard HTTP methods such as GET, POST, PUT, DELETE, HEAD, OPTIONS, TRACE, CONNECT, and PATCH. These methods are used to transfer data between two endpoints.
Create a Database Connection.
You need to connect to the database before you can start building your application. This is done using the mysql_connect() function.
Define the HTTP Request Methods.
There are three main methods of communication between a client (the user) and server (your website): GET, POST, and DELETE. These are called request methods because they describe what type of data will be sent with each request.
Implement the GET Method.
The GET method is the simplest one. It sends no data at all. Instead, it asks the server for a resource identified by its URL. This means that when you use the GET method, you’re telling the server to return the contents of a particular file.
Implement the POST Method.
The POST method is more complex than the GET method because it requires sending some data along with the request. You can send any type of data using the POST method, but there are two common ones: application/x-www-form-urlencoded and multipart/form-data.
What is an API?
API stands for Application Programming Interface. The API provides a set of rules or protocols by which software components may interact with each other. The API interface definition describes how messages should be formatted and transmitted between applications. APIs often provide a standard way of integrating two different applications.
The REST API uses HTTP methods to transfer data. The REST API uses JSON format.
REST stands for Representational State Transfer. REST API is based on stateless architecture. REST API does not maintain any kind of session across requests.
HTTP is a protocol that specifies how web servers communicate with clients. Web browsers send HTTP request to a web server using GET method. A web browser sends a GET request to a web server if it wants information from the server.
GET stands for Get. GET method retrieves specified resource from the server.
POST stands for Post. POST method creates a new resource on the server.
PUT stands for Put. PUT method replaces existing resource on the server. PUT method overwrites the contents of a file.
DELETE stands for Delete. DELETE method removes a resource from the server. DELETE method deletes a resource permanently.
Let us observe some of the important SDLC Interview Questions for Business Analyst.
SDLC Interview Questions
What is SDLC?
SDLC stands for software development lifecycle. It is a set of processes and activities that are performed throughout the entire life cycle of developing software. These processes help ensure quality products are delivered to customers.
How does SDLC differ from waterfall model?
The waterfall model is a traditional approach to software development where requirements are gathered at the beginning of the project and then followed by design, coding, testing, and deployment. In contrast, the agile methodology focuses on delivering working software frequently, responding to changing customer demands, and incorporating feedback early and often.
How do you define Agile?
Agile is a collection of methods, techniques, and practices that promote collaboration among cross-functional teams to produce high-quality software. Agile emphasizes self-organizing teams, continuous integration, and short iterations.
What are some advantages of using Agile methodologies?
Using Agile methodologies helps teams focus on building great products rather than spending time managing processes. Teams can respond to changes in their environment more effectively. By focusing on delivering working software frequently and iterating continuously, teams can incorporate feedback early and often. Agile methodologies encourage transparency and communication between team members.
What are some disadvantages of using Agile method?
Teams may not have enough time to plan ahead and prepare for upcoming tasks. Using Agile methodologies requires a lot of upfront planning and preparation.
What is Scrum?
Scrum is a framework for organizing work and tracking progress in small increments called sprints. Each sprint contains a series of tasks that are completed over a period of two weeks. At the end of each sprint, the team meets to review what was accomplished and discuss how they can improve upon the previous sprint.
What is Kanban?
Kanban is a visual management tool that provides a way to track workflow and prioritize tasks. Kanban boards display information about current projects and allow users to visualize the flow of work. Kanban boards are useful for keeping track of the status of ongoing projects.
What is the difference between a waterfall model and agile methodologies?
Waterfall Model: In the waterfall model, each phase of the project is completed before moving onto the next phase. Agile Methodologies: In agile methods, teams work together to complete the project at the same time.
How would you define SDLC?
The Software Development Life Cycle (SDLC) is a series of steps followed while developing software. These steps include requirements gathering, design, coding, testing, deployment, and maintenance.
What should I expect from an SDLC interview?
What do you want to achieve?
This question is often asked at the beginning of any project. You need to know what you want to accomplish before you begin working on the project. If you don’t have a clear idea of what you want to accomplish, then you won’t be able to create a plan to get there.
How long does the project take?
The length of time it takes to complete the project is dependent upon many factors including scope, complexity, team size, skill level, etc. However, if you’re not sure how much time it’s going to take, you might consider breaking down the project into smaller pieces. That way, you’ll be able to estimate the amount of time each piece will take and adjust accordingly.
How will you measure success?
Successful projects are measured by their outcome. You may choose to use quantitative measures (e.g., number of units produced) or qualitative measures (e.g. customer satisfaction). Regardless of the type of measurement you choose, make sure that you define what success looks like for your organization.
Who else will be involved in the project?
You should always involve others who will be affected by the project. These people could be internal stakeholders (i.e., employees), external stakeholders (i.e. customers), or both. Make sure that everyone understands the goals of the project and agrees to those goals.
What are the risks associated with the project?
Risks are anything that can happen that would prevent the project from being successful. Risks can be divided into two categories: known and unknown. Known risks are things that you already know about and can account for them ahead of time. Unknown risks are things that you don’t know about until they occur. When dealing with unknown risks, you should try to mitigate them as best as possible.
What are the dependencies of the project?
Dependencies are tasks that must be completed before you can start work on the project. Dependencies can be broken down into three types: mandatory, recommended, and optional. Mandatory dependencies are tasks that must be done first. Recommended dependencies are tasks that you should do first unless there is a compelling reason not to. Optional dependencies are tasks that you can do later if necessary.
What is the schedule for completing the project?
A schedule is a timeline that shows when different activities will be performed. A good schedule helps you to stay organized and manage expectations. It also gives you a sense of urgency and lets you know when you need to start doing something.
How do I prepare for an SDLC interview?
Research the company
Before applying for any job, research the company thoroughly. Find out what their mission statement is, how they operate, who their clients are, etc. You want to make sure you’re going to fit in well with them and that you’ll have something in common with the people you work with.
Prepare yourself mentally
Prepare yourself mentally for the interview. Know what questions you’re going answer and what you’re going say beforehand. Practice answering these questions aloud if possible. If not, then write down some sample answers beforehand and practice reading them off of paper.
Dress appropriately
Dress professionally. Wear clothes that are clean and pressed. Make sure your hair is neat and tidy. Don’t wear anything that might distract others from your appearance.
Be confident
Be confident! Even if you don’t feel confident, fake it until you make it. Pretend you’re excited about the opportunity and act like you know everything about the company.
Smile
Smile! A genuine smile goes a long way. People will notice it and it will give you a positive vibe.
Have fun
Have fun! Enjoy yourself and enjoy the experience.
Show enthusiasm
Show enthusiasm for the position. Show interest in the company and show excitement about the opportunity.

2.When wire-frames to be created?
The wireframes or mockups or prototypes should be created before the software development is started. It helps to minimize rework and save the resource time.
If we are following waterfall methodology then wireframes should be created before development stage.
It does not matter how we are preparing the wireframes but ensure it is important that the wireframe designer (UI/UX designer), understands the information that has to be displayed on the screen.
The designer or UI developer has to really understand how the user will interact with the system. If they understand clearly what is the requirement then only they can prepare the wireframes.
So it is very important that requirements should be gathered properly before creating wireframes.
As we discussed in previous articles requirements can be gathered with using multiple elicitation techniques and same will be documented in relevant artifacts.
As requirements will be updated as User Stories or use cases, same will help to design the wireframes.
3.Advantages of Wire-frames.
a.By using wire-frames we can prevent the rework.
b.It saves resources time.
c.Wire-frames are easy to use and understand.
d.It avoids the confusion and misunderstanding within the team members.
e.Wire-frames are used by the team to have a share understanding of the same information.
f.Wire-frames are used to help design the user interface.
g.Coding (Technical) skills not required.
4.How to create wire-frames?
There are tools available to create wire-frames. Some of the tools are free and open source; we can use the same to create wire-frames.
And even with using paper and pencil also we can design the wire-frames; or by using white board and pen also we can create the wire-frames, the ultimate goal to create wire-frame is make developers to understand what and how the screen should be.
But using software also has advantages such as data storage, data retrieval and wire-frame reusability. If we use software then we can use this wire-frames in future also when ever required.
To properly create the wire-frames, we need to understand what the buttons to be available in screen are and what the functionality is. And we need to understand what fields to be available on the screen.
By using some open source tools we can create the wire-frames even if you do not have the coding skills.
5.Why wire-frames are required?
There are so many ways to document the requirements and make development team to understand, but wireframes will help to understand the requirement clearly. Wireframes are easy to draw and easy to understand.
FAQ’s
What are wireframes in design?
The designs you received are called wireframes (sometimes called wires, mockups, or mocks). A wireframe is a schematic, a blueprint, useful to help you and your programmers and designers think and communicate about the structure of the software or website you’re building.
What is the use of wireframe?
A wireframe is commonly used to lay out content and functionality on a page which takes into account user needs and user journeys. Wireframes are used early in the development process to establish the basic structure of a page before visual design and content is added.
What are wireframes and mockups?
A mockup is a static wireframe that includes more stylistic and visual UI details to present a realistic model of what the final page or application will look like. A good way to think of it is that a wireframe is a blueprint and a mockup is a visual model.
What should wireframes include?
A wireframe is a two-dimensional illustration of a page’s interface that specifically focuses on space allocation and prioritization of content, functionalities available, and intended behaviors. For these reasons, wireframes typically do not include any styling, color, or graphics.
What are the different types of wireframes?
There are three main types of wireframes: low-fidelity wireframes, mid-fidelity wireframes, and high-fidelity wireframes.
Is Wireframing UX or UI?
Wireframing is a practice used by UX designers which allows them to define and plan the information hierarchy of their design for a website, app, or product. … Without the distractions of colors, typeface choices or text, wireframing lets you plan the layout and interaction of your interface.
We discussed and observed what is Scrum and Scrum Roles, now we look into some other important terms and terminology. That is what is Sprint and what are Scrum Meetings and what team discuss in Scrum Meetings.
We can say Sprint is nothing but Time Frame. Team discusses and decides what the prioritized items are and how much effort required achieving that. For example 3 user stories/ Requirements prioritized items are in product backlog, so team discuss about these three user stories, how much effort required and how many man days required to complete these prioritized user stories in this sprint.
For example Sprint duration is 2 weeks, and then team needs to complete those 3 user stories within this time frame, which includes, Design > Development > Test > Integrate.
Scrum Meetings:
Daily Scrum Meeting:This happens every day where team will just discuss on 3 questions. Everyone should participate in this meeting, and meeting should be completed in 15 to 30 minutes.
What did you do yesterday?
Here you need to explain what you have done yesterday and what the status of tasks assigned to you is.
What will you do today?
Here you need to explain what you will do today to complete the assigned task as per schedule.
Is there any impediments stopping you?
Here you need to explain if you are facing any issues to complete the assigned task. For example your task is depending on another task or functionality and it is pending with some other team. Then you need to explain the same in meeting, then Scrum Master will take a call and discuss with the concerned team to resolve the issue. Scrum Master Note down these points and discuss offline with concerned teams.
These questions are depending on your scheduled Daily Scrum Meeting. For example if your meeting is at Morning then above questions will applicable.
If your meeting is scheduled at evening then questions as below.
What did you do today?
What will you do tomorrow?
Is there any impediments stopping you?
Every team member of the team should participate in this meeting and need to update the status. As every individual team member should participate in this meeting, Scrum Master will discuss with individuals and schedule meeting as per convenient time.
For example you are working on Indian standard time as you are in India, but if your development team in some other country, then Scrum Master should coordinate and schedule meeting as per convenient time, and Scrum Master is the responsible person to ensure every team member joins in meeting.
Sprint Review Meeting or Scrum Review Meeting: This will happen at the end of the sprint where team will give demo on completed stories to product owner. As per above example Sprint completed in two weeks, then team will have this meeting and give demo on developed product. Usually it will take 3 to 4 hours.
Sprint retrospective Meeting:This will happen at the end of the sprint where team will answer these 3 questions.
What went well in the sprint?
What did not go well?
What are the required areas of improvements in next sprint?
This is continuous process, team discuss at the end of every sprint to improve the quality.
You may get this question in interviews also what are scrum meetings and what team will do in these meetings.
I hope it helped to provide overview of What are Scrum Meetings.
To know more about what are scrum meetings and what is scrum we can visit scrum official website.
Scrum: Scrum is not a methodology, Scrum is a framework. That means it provides opportunity to work as per the project needs or requirements with cross functional team to reach the project goals. It helps us to interact with the people easily.
Scrum is very popular now days and we can say without putting Agile in your resume you will not get even interview calls also. Don’t worry and do not think too much to understand what is scrum. Let us discuss in simple words.
Mostly it will use in implementation of projects.
When we are discussing about Scrum, we should understand and remember the ScrumTerminology and terms used. I am trying to explain in simple way.
Product Backlog:
Need to prepare the product backlog, it contains the list of user stories, user story is nothing but requirements.
Once we prepare the Product backlog, will prioritize the user stories which can be implemented in this Sprint.
: He will decide what needs to done in this sprint/project and he is the responsible for managing the product backlog. He will be the responsible person for product like how product should be and all.
He interacts with Business Analysts and Customers. This role may be played by BA or any person who is having strong knowledge on product and who works with end users for a long time. Depends on the project client also may play this role.
He will monitor the performance of the team within the sprint. Team will raise all their concerns and issues to ScrumMaster.
He is responsible to provide solutions to the team. He will interact with the stake holders to address the issues and concerns raised by the team. This role can be played by any person in team usually Business Analyst will play this role.
Initially I was also thinking what is JIRA and how to use JIRA, JIRA is a project management tool. It can be used to track the requirements status like what is the current status of the requirement assigned to user whether it is open or closed or under processing.
We will discuss in detail what is JIRA and advantages of using JIRA?
Here I am not going to explain how to use JIRA and all, I am trying to provide overview about JIRA tool.
What is JIRA?
JIRAis a tool developed by Australian Company Atlassian. This software is used for bug tracking, issue tracking, and project management. The name “JIRA” is actually inherited from the Japanese word “Gojira” which means “Godzilla”. The basic use of this tool is to track issue and bugs related to our project.
Jira is especially useful for software development because it has built in templates that can be used to help you create a software development project.
For example Jira has a Scrum template that can be customized to fit in with your requirements.
The template can be used to create the development project, once your development project is created, then you can create your backlog, plan your sprints, and your software releases.
A Scrum board would also be created with different columns. The columns show the different status that the cards are in such as backlog, development, Quality Assurance (Q & A), demo and closed which shows the status of the cards.
A kanban board also already available, we can customize as per our requirement. We can use Scrum board or Kanban board as per our requirement.
Has below standard formats.
Scrum board tracking.
Kanban board tracking
Cumulative flow charts.
Burn down charts.
Sprint reports.
We can create customized boards as per our requirement. It helps us to understand how many tasks we have and what the status of each task is.
Assume we have 5 developers in our team, and we have 50 requirements in our hand, and out of 50 requirements 20 prioritized. So here we need to assign these tasks to our developers.
So here I can customize the boards and fields as per my requirement. If we observe in above example 30 requirements yet to prioritized so I can mark status as “to be process” and 20 requirements I need to assign to my developers. So we can assign 4 tasks to each of the developers and I can give the due dates also as per the requirement.
As per above example 4 I assigned to X and 4 assigned to Z, so here I can track the requirements x is having how many tasks in his bucket and how much time required to complete the task and actual hours taken to complete the task.
We can track the same for Issues also.
Issue Tracking : Jira can also be used to track issues during software development. It can be used to identify and create new issue tasks, prioritize issues for completion, and track them using a workflow.
You can specify details about the issue which helps with replications and resolution.
Time tracking: Jira can be used to keep track of the the time spent on tasks and issues. This would help with future sprints planning. The time tracking views available include :
Working hours per day
Working hours per week
WorkFlows
A JIRA workflow is a set of statuses and transitions that an issue goes through during its lifecycle. JIRA workflow encompasses five main stages once the issue is created.
Before accepting or committing any requirement, as a Business Analyst, first we need to do the feasibility study, during (feasibility study) analysis we need to concentrate on below.
The requirement is feasible or not.
Whether it will impact any existing functionalities.
Whether this requirement may cause to any performance issues.
Whether this requirement fits in the current system or not.
What are the dependencies on this requirement?
What are the integration points?
Any impact on integration points?
You can discuss with internal and external stakeholders to understand the requirement clearly, if we not understand requirement clearly, then there is a chance to miss out some functionalities. It may lead to system issues/ bugs or client escalations.
If we delivered defect product then client will not happy and they may lose confidence on us. So it is very important to understand the requirement clearly before committing to client.
A Analysis is a preliminary analysis of solution alternatives or options to determine whether and how each option can provide an expected business benefit to meet the business need or requirement.
A Analysis may address either a business problem to be resolved or a business opportunity to be exploited.
We can do the feasibilitystudy based on the resource and data available with us. Some tools also can be used to do the feasibility study.
The feasibilitystudy is an integral part of formulating a major business transformation project. Eg. Re-engineering a core business process and supporting technology, establishing a new line of business, increasing market share through acquisition, or developing a new product or service.
Let us discuss and observe who project manager is and what he does in project. Till now we have discussed the role and responsibilities of Business Analyst in project. And we may have get doubt as “Business Analyst is handling the project and he is involving in every phase of the software development life cycle.
Business Analysts are usually active members of project teams and many business analysis tasks are very similar to project management tasks, but who exactly is a Project Manager?
As we discussed and observed in previous articles business analysts involves almost all the phases of the software development life cycle.
Requirements gathering
Requirements Analysis
Design
UAT
Functional Testing
Production Movement
Maintenance and Support
Business Analyst involves in above phases based on the project and organization. Now a day’s some of the organizations expecting even technical skills from the Business Analyst.
As Business Analyst involves in all the phases of the software development life cycle but Project Manager is the person who can take decisions and who can decide how project should be and how project to be drive in smoothly to reach the customer expectations and meet the project goals.
He / She is the person who can decide which methodology to be used and project manager is the person to design the project. Project Manager is the responsible for the entire project.
What are the skills needed to prove as a good project Manager.
They have to be able to manage people and develop trust and communication with the project’s stakeholders in order to ensure the project’s success.
He/ She has to be able to adapt to change, work well under pressure.
He/ She is responsible for using their skills and techniques to ensure the project’s success.
Some of the important responsibilities are below.
