What are the Advantages of Waterfall Model?

• Simple and easy to use
• Easy to manage – each phase has specific deliverable’ s and a review process
• Phases are processed and completed within scheduled time
• Works well if requirements are very clear

• It is one the easiest model to manage. Because of its nature, each phase has specific deliverable’s and a review process. In each phase we will get to know what to deliver and when to deliver.
• Faster delivery of the project
• Process and results are well documented and documentation plays important role in Waterfall methodology.
• Easily adaptable method for shifting teams.
• This project management methodology is useful to manage dependencies.
• It works well for smaller size projects where requirements are easily understandable.

Disadvantages:

• Handling change request is difficult.
• Feedback from the client is not there.
• There may be chance to no coordination between the teams.
• Team work and coordination is not there
• Continuous improvement process

• This model is not suggestible for Large projects
• If the requirement is not clear at the beginning, we can’t use waterfall methodology because every phase is dependent on previous phase.
• Here next phase will start once previous phase completed.
• Very difficult to move back to makes changes in the previous phases.
• The testing process starts once development is over. Hence, it has high chances of bugs to be found later in development where they are expensive to fix.
• There is no team work in this model.
• Difficult to manage change requests in this model.

FAQ’S

What is waterfall model?

Definition: The waterfall model is a classical model used in system development life cycle to create a system with a linear and sequential approach. It is termed as waterfall because the model develops systematically from one phase to another in a downward fashion.

What are the 5 stages of waterfall model?

Phases of waterfall project management differ from one project to another. But generally, you can group the activities of the waterfall approach into five stages: planning, design, implementation, verification, and maintenance.

What is waterfall model in SDLC?

The Waterfall model is the earliest SDLC approach that was used for software development. The waterfall Model illustrates the software development process in a linear sequential flow. This means that any phase in the development process begins only if the previous phase is complete.

Why is waterfall model used?

As an internal process, the Waterfall methodology focuses very little on the end user or client involved with a project. Its main purpose has always been to help internal teams move more efficiently through the phases of a project, which can work well for the software world

Where is waterfall model used?

The waterfall model is most commonly used in software engineering and product development, less often – in other projects and industries. Employ the waterfall model only if your project meets the following criteria: All the requirements are known, clear, and fixed. There are no ambiguous requirements.

What are the 7 phases of waterfall model?

The waterfall model is a sequential design process in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance.
