Software Development Life Cycle (SDLC)

Kirana Store

Software life cycle models describe the phases of the software cycle and the order in which those phases are executed.

SDLC There are tons of models, and many companies adopt their own, but all have very similar patterns.  The general, basic model is shown below:

•Output of the first stage is input of other.  •Requirements are translated into design.  •Code is produced during implementation that is driven by the design.  •Testing verifies the deliverable of the implementation phase against requirements. Kirana Store

Explanation in brief... 1. Requirement Stage…

Business requirements are gathered in this phase

This Stage Answers:-•Who is going to use the system?  •How will they use the system?  •What data should be input into the system?  •What data should be output by the system?

2. Design Stage… •The software system design is produced from the results of the requirements phase. •This is where the details on how the system will work is produced.

Continued... 3. Implementation… In implementation stage code is produced from the deliverables of the design phase, and this is the longest phase of the software development life cycle.

4. Testing…. The final product is tested against the requirements to make sure that it is actually solving the needs addressed and gathered during the requirements phase & working as per the client’s requirement.
