Incremental Model - tugosera/tralalero-tralala GitHub Wiki
-
Definition: Product is built and delivered in increments (partial systems), each adding functionality.
-
Approach: Build part of the system → Deliver → Build next part → Deliver, etc.
-
Focus: Delivery of complete features step by step.
-
User Feedback: After each increment.
-
Example: First increment = login module, second = dashboard, third = reports.
Pros:
-
Early delivery of working software.
-
Easier testing and debugging.
-
Lower initial delivery time.
Cons:
-
Requires detailed planning.
-
Integration issues may occur.
-
Scope creep risk if not managed.
-
Definition: The system is developed in iterations, each refining the previous one.
-
Approach: Build → Test → Evaluate → Improve, repeat until final product.
-
Focus: Refinement and improvement.
-
User Feedback: After every iteration.
-
Example: First version = basic functionality, next iterations enhance features and fix issues.
Pros:
-
Continuous improvement.
-
Early risk handling.
-
Allows feedback-driven changes.
Cons:
-
Requires more management.
-
Risk of endless iterations.
-
Not ideal for small projects.
