Iterative vs Incremental Model-Differences
Here are the key differences between the iterative and incremental model(iterative enhancement model):-
Aspect |
Iterative Model |
Incremental Model (Iterative Enhanced Model) |
---|---|---|
Development Approach |
Repetitive cycles with continuous refinement |
Delivering the software in functional parts |
Flexibility |
Highly flexible and adaptive to changes |
Offers flexibility but less than iterative |
Testing |
Testing is integrated throughout the cycle |
Testing is done for each increment |
Delivery of Features |
Complete features are developed in each iteration |
Features are delivered incrementally |
Risk Management |
Risks are identified and addressed in each cycle |
Risks are managed as increments are delivered |
Client Feedback |
Feedback is collected and incorporated regularly |
Feedback is obtained after each increment |
Project Visibility |
Provides a clearer view of the project’s progress |
Offers visible progress with each delivered increment |
Dependency Management |
Dependencies can be identified and resolved in each iteration |
Dependencies between increments need careful management |
Completion Time |
May take longer to deliver the complete product |
Allows for partial delivery in shorter timeframes |
Example Analogy |
Writing a draft and refining it multiple times |
Building a house floor by floor |
Iterative vs Incremental model in Software Development
In software development, there are two main approaches: Iterative and Incremental. The Iterative model involves repeating cycles of development, allowing for continuous improvement as the project evolves. It’s flexible and adaptive to changes. On the other hand, the Incremental model focuses on delivering the software in smaller, functional parts, building upon each increment. Both methods aim to enhance the development process, but they differ in how they handle repetition and the delivery of project components.
