Software Development Life Cycle (SDLC)

Test plans and test cases serve to ensure that the software meets the requirements established during each development stage, allowing for parallel verification and validation.

The Big Bang Model is characterized by minimal planning, high programming efforts, and reliance on significant funding, without a structured process or clear requirements.

The advantages include low initial planning and flexibility, while disadvantages involve unpredictability and difficulties in managing large projects due to arbitrary input requirements.
