SDLC

Question 1

Planning phase steps:

Answer 1

1. Business Idea: The client has an idea to improve the business (application/website)
2. Requirement Gathering: PO (Product Owner) or BA (Business Analyst) gathers the requirements
   from the client
3. Feasibility Study: The product manager, finance team, HR team, architects, and PO get together
   and make a decision if they can take the project or not. They mainly talk about three topics.
   a. Do they have enough resources (developers and test engineers) to take the project?
   b. Do they have a system set up, like a lab?
   c. Do they have enough technology to develop this project?
4. Requirement Analysis: Operations, developers, testers, architects, and PO get together and discuss the requirements in detail.
   PO creates the user stories and puts them into Product
   Backlog.

can discover things that do not make sense and help redesign the flow in the early stages of the
development.

Question 6

Testing
