Question

What is the difference between Systems Development Life Cycle SDLC and Agile development methodologies? Explain in multiple paragraphs. No handwriting, please.

Answer 1

A traditional systems development life cycle project consists of requirement analysis and planning done at the beginning of the project and the entire project execution is planned based on the initial requirement analysis stage. Any kind of change management at a later date is difficult as it affects the entire project cycle. And the entire project tasks are laid down with date assigned to each milestones based on the forecast and predicted project map.

Agile methodology is on the other hand more adaptive and there is no detailed planning at the outset and the project or product evolves through a series of iterative stages which involve requirement analysis, designing, building and testing each prototype and then migrating to the next stage. There is much more customer interaction in this methodology and since it is more flexible and iterative in nature, the scope of future changes is always there.
