Traditional methodologies

1. Waterfall Model

   • Linear & Sequential, and Documentation-Driven
   • Requirements → Design → Implementation → Testing → Deployment → Maintenance.
   • It's recommended for well-defined, stable projects with minimal expected changes.

2. Rational Unified Process (RUP)

   • Inception → Elaboration → Construction → Transition.
   • Focuses on defining and refining system functionality via use cases.
     • Divides the project into cycles with multiple iterations.
     • Ideal for complex and evolving projects requiring adaptability and risk management.

3. V-Model (Verification & Validation Model)

   • Each development phase has a corresponding testing phase and is tested before proceding
     • It allows to test early stage errors
   • Requirements → Design → Implementation → Unit Testing → Integration Testing → System Testing → Acceptance Testing.
   • Mostly used for critical systems where testing at every stage is crucial (e.g., healthcare, aerospace).
