Agile VS Waterfall

Agile and Waterfall both are the Best Methodologies, the drawbacks depends upon the project. Let us Understand what is Agile Methodology and what is Waterfall methodology to know what is the best methodology. Waterfall Methodology: It’s a Step by step approach and we call it Linear approach. The name for this methodology selected waterfalls because water flows from up to down, like wise in this methodology we have different steps involved. Step1, Requirement gathering: The very first step in the waterfall methodology is Requirement Gathering, In Requirement Gathering the Business Analyst will Try to understand the Business and its objectives, model everything and gathers the requirement Using elicitation techniques, asks Questions like what is this project, what are the problems facing in the manual process, why do you want to automate it now, who are the end users, How is this going to benefit the Business everything and what are the features they require for the automation. Step2: Requirement Analysis: Once the requirements are gathered then we draw the UML diagrams, Activity diagrams, flow charts, to Understand better, also create the Prototypes, it will be shown to the stakeholders, the stakeholders review and it is easy for them to understand and add if anything is missing. Step3: Design Phase: in the Design phase the Business analyst co-ordinate with system Architect and does the User interface, and design how the process should happen, everything they will discuss in here. Onces the signoff is done from the business and stakeholders next step is develop the website. Step4: Coding: In this stage the developers will start coding and if any other information is required as a Business analyst I will help them clear their issues. Step5 Testing: BA and Testers will write the test cases and do the testing process, if any errors then developers need to rework on those. Step6: Deployment: IN this stage they move the code from development to production server. And UAT the stakeholders will do the UAT, BA guides them to complete the process. Once the UAT is done then we get the Project signoff. This is the waterfalls methodology. Agile: Agile is an Iterative approach, it’s a Mindset, in agile all the process work parallelly. Agile is used mostly in the developing world the changes are common, in waterfalls once the signoff is done the changes are not possible, Business needs Flexible methodology. The Business analyst will do the market Research, Enterprice Research, Backlog management, Product Vision everything. Here there will be different frame works, the popular one is Scrum to develop a software products, In scrum we have product backlog, sprint backlog, Increment we call this as Scrum Artifacts, and we have 3 accountabilities which is Product owner, Scrum master, Developers. We have 5 meeting we follow in the scrum 1) sprint 2) sprint Planning 3)Daily standup, 4)sprint review, 5) retrospective. We have sprint that means it’s a 2 to 4 weeks duration. In each sprint we have to provide the increment. The stakeholders does not need to wait for 9 months to complete the project, they can use it once the MVP(minimum Viable Product) is done. They can give changes and all the things in agile is transparent. The stakeholders will know what is happening in the project. So In this modern changing world Agile is the Best Methodology that handles changes, the stakeholder can use the product in initial stages. We have lots of benefits like there is less Documentation in the projects etc.
