Waterfall Model: A Better Way for Software Development


3 Mins Read Time

The Waterfall Model


Classic and the most traditional Software development lifecycle (SDLC) model that has a systematic, sequential, and flexible approach to software development in software The Waterfall Model.

What does the outcome depend on? This question has a sure-shot answer that is the inputs and the process because it’s the methodology of how good or bad that decides the quality of the by-product. As a project management officer, the choice on which software development lifecycle model to choose is a challenging and crucial task as it defines the flow of the process.

Software development lifecycle (SDLC) is the methodology that is defined in terms of graphical representations and marks the different stages in which the software development transits. A list of activities is performed on the software right from inception to retirement as per the business plan.

Classic and the most traditional Software development lifecycle (SDLC) model that has a systematic, sequential, and flexible approach to software development in software The Waterfall Model. Toyota uses this Software development lifecycle (SDLC) methodology.

The Waterfall Model is used for the development of enterprise applications where the business requirements are defined well in advance and the changes/modifications are minimal as possible. The popular applications of the Waterfall Model are as follows:

  • Customer Relationship Management(CRM) Systems
  • Supply Chain Management Systems
  • Inventory Management Systems

The Waterfall model was first documented in 1970 by Royce and was adopted by many top-class companies because of the flexible implementations. The Waterfall model is seen as a downward flow and it comprises of following steps or stages to be specific:

Communication -


The main aim of the business communication phase is to gather the business requirements. Effective communication helps to find out what the user or business requires. In this phase documentation of the business and software requirements. It could be called the most critical phase as it decides the layout for the by-product creation.

Planning -


Planning involves activities such as the creation and maintenance of schedules, efforts estimates, tracks, and checklist of processes. It also quotes the budget and potential risks involved. At this point, the business plan is ready.

Modeling -


Popular and the most significant phase where AS-IS and TO-BE requirements are compared. This involves analysis of the In-Scope and Out-Scope defined in the Communication or Requirement gathering phase.

Construction -


In this phase, the software is developed and coded to meet the business requirements. Testing inclusive of unit testing and UAT testing is done and this forms an integral part of software construction.

Deployment -


The business-approved changes are rolled out or released in the Production environment. Potential errors and bugs are also reported if any. These setbacks are taken as a part of post-production support activity. Feedback on quality is acquired in the deployment phase of SDLC.

Pros of the Waterfall Model: The Waterfall Model has numerous benefits to offer though it is a traditional and old-fashioned model. Enlisted are the advantages provided by the Waterfall Model.

  • Well-defined structure: The requirement gathering phase is defining the layout for the design and development of software.
  • Time-saving: As the Waterfall Model defines the business requirements and a business plan at the very state it saves a lot of time for the developers and designers.
  • Fewer errors and risks: At every major stage, goalposts are marked and developers test before transiting to another stage which reduces errors or bugs.
  • Ease management: The analysis says that the Waterfall Model is the most easiest and effective Project management technique.
  • Documentation: The design process becomes simpler and structured because of the emphasis on documentation at every phase of the software development lifecycle (SDLC).
  • Less resource involvement: Minimal resources are required for the development of software because it adopts a linear approach

Setbacks of the Waterfall Model: Waterfall style models are not as responsive as other Software development cycle (SDLC) models are available. The possible disadvantages or setbacks are as follows.

  • Cannot go backstep: The advantage of linear design dependency at times proves to be a setback because you cannot go backstep from one phase to another.
  • Post-production bugs: Minor bugs or errors after go-live can at times be a tedious job for developers.
  • No client involvement: This type of software development methodology keeps clients or users away from the development cycle and this creates a lot of confusion in the design process.
  • Time-consuming testing: Due to testing at various stages and dependency there are delays in the design process that makes it difficult to meet deadlines.

Agile Model VS The Waterfall Model: A more sequential and rigid approach in Software development lifecycle(SDLC) is the Agile methodology. This has definite requirements with minimal or no changes entertained during the development process. It has a limited team of experts working on a complete project with fixed project details and limited team coordination. Whereas the requirements are ever-evolving in the Waterfall Model with a high degree of coordination. In addition to this testing comes after development unlike concurrent tests in The Waterfall Model.

The Final Verdict:

On discussing the most traditional and classic Software Development Lifecycle(SDLC) model. The advantages and disadvantages we conclude that DevOps doesn’t prefer the Waterfall Model as it opts for the Agile approach.
