Answer:
- The linear and rigid nature of waterfall method of SDLC.
Explanation:
Software development life cycle or simply SDLC are stages or processes that a licenced software company must follow to design, develop, deploy and maintain a functional application.
There are two main SDLC processes, they are agile process and the traditional waterfall process. The agile process allows for sprint or parallel and repeated execution of the stages in the process, but the waterfall process allows for serial execution of stages, where one stage must end before the other begins. This makes the agile process fast and reliable.
In the agile process, software design is flexible, can be changed at any time without affecting it's operation, but in waterfall, all designs must be concluded before the next stage and cannot be changed afterwards.
