The third step of the SDLC has 3 phases, specifically, developing several system proposals, selecting the most feasible proposal, and reporting on the selected system to be developed. This step is called the system ___ step. Multiple Choice design development introduction analysis

Software requirement and estimation.

Explanation:

In this step, the proposals are collected, and best from them is made, and then checked for feasibility, and the SRS document is formulated finally. Now the each developer, designers, writers are being assigned the task, then finally the development phase starts. However, since this is SDLC, you will not find any iteration, and the defects are checked only after testing which is the last phase. And a lot of errors remain even after delivery sometimes. Also, it is time consuming to edit the errors in this manner. Hence, agile methodology is preferred.
