The waterfall model methodology (here, we will discuss the waterfall model vs agile model) is also known as the linear or sequential model. This is a sequential model, so the next step is completed only when its previous step is completed.
Different software development phases can be divided into additional steps to compare waterfall methodology vs agile, including System Analysis and Design, Requirement Gathering, Implementation, Testing, Deployment, and Maintenance. All phases are executed sequentially in the given order. Here we are going to describe the agile vs waterfall concept clear to you. Here we will also discuss the following points:
These points are discussed in the context of agile methodology vs waterfall model.
Along with these requirements, there are some limitations as well of this model due to which sometimes waterfall model vs agile is often discussed, and they are listed below:
These are some of the advantages and limitations of the waterfall model. We study the waterfall vs agile model. Some of the organizations like to adopt agile methodologies. Let us know what the Agile method is to make the agile vs waterfall concept clear to you?
Agile methodology helps in the continuous iteration of the development and testing process. Here in this methodology, the development and testing activities are concurrent, unlike the Waterfall model. The agile model helps in managing communication between customers, developers, managers, and testers. Sometimes we have to study agile methodology vs waterfall cases.
Both of these methodologies are used to develop software projects. Still, there are some differences as well, and we study agile methodology vs waterfall that make one choose one over another and make the agile vs waterfall concept clear to you. Let us see the differences:
Waterfall Method Vs Agile Table
|The incremental approach is followed.
|This is a sequential design process.
|Agile methodology is quite flexible.
|The waterfall model is a sequentially structured software development methodology and sometimes becomes quite rigid.
|Agile is a collection of many different projects.
|The development of the software is done as a single project
|The project development life cycle is separated into a sprint in an agile process
|In this model, the complete process is divided into distinct phases
|Agile is a flexible method that can be used to make changes in the project development requirement even after the completion of the initial planning
|In the waterfall model, the software development process is divided into distinct phases
|Plan Review Possibility
|The test plan is reviewed after each sprint
|The test plan is discussed during the test phase
|Change in Requirements
|In the agile development process, the requirements keep on changing and refreshing
|The waterfall models have definite requirements for which the changes are not expected
|In agile methodology, the testing is performed concurrently with application development
|Here in this methodology, the phase of “Testing” comes after the “Build” phase
|Small and dedicated teams are usually offered with proper coordination and synchronization
|The coordination and synchronization of teams is very limited
|Alteration in Project Requirement
|The project description can be altered at any time during the full development lifecycle of the process
|Detailed software development description is implemented by following the waterfall approach
|An entire agile project is managed by an entire team so there is no need for the project manager
|The waterfall model follows the straightforward approach to managing the project and therefore project management is an imperative part of SDLC
|Every day the requirement is prepared by the project owner and team to speed up the work during the full lifecycle of the project
|Business analyst prepares the requirement of the project before its initialization
|Customer Requirement Fulfillment
|The agile methodology takes software as a product that must satisfy the customer’s need and can be changed as per customer requirement
|The waterfall model does not take software as a product and focuses completely on project accomplishment.
|Agile methodology is iterative and incremental
|Waterfall methodology is linear and sequential
|The project can be easily scaled due to its iterative approach
|Project scaling is difficult in waterfall methodology
|Requirement of Formalized Document
|Formalized documentation is not necessary for the Agile method. A working prototype serves as the best tool for customer feedback and evaluation
|The waterfall model required formal documentation
|Frequent customer or client engagement and interaction is involved during the development lifecycle.
|The end-user or customer requirement is frozen at the initial step. The product is provided to the customer only when it is entirely built.
Today most companies are using Agile methodology due to its benefits and know the waterfall methodology vs agile. Some organizations, especially those in the development of small projects, are using waterfall models. Here we have presented a detailed description and agile vs waterfall comparison table of the difference between both methodologies as agile vs waterfall.
Agile methods may be suitable for some cases, while other waterfalls may be the best ones. The agile vs waterfall pros and cons help in selecting the best one. Choose the one that suits your requirement exactly as you know the pros and cons of agile methodology vs waterfall model.
