Incremental Life Cycle
A delivery approach that releases complete, usable pieces of the product throughout the project so customers can start using value right away.
Key Points
- Delivers finished, usable functionality in stages (increments).
- Each increment meets quality standards and can be deployed or used immediately.
- Enables early value realization and stakeholder feedback to inform subsequent work.
- Differs from iterative approaches by adding new completed features rather than repeatedly reworking the same ones.
Example
A team building a learning platform first releases user registration and course browsing, which learners can start using. Next, they add secure payments, then progress tracking, and later discussion forums. Each release is complete and usable on its own, delivering value earlier while the full platform evolves.
PMP Example Question
A sponsor wants parts of the product to be ready for use before the entire project is finished. Which life cycle best aligns with this need?
- Predictive (waterfall) life cycle
- Iterative life cycle
- Incremental life cycle
- Hybrid life cycle
Correct Answer: C — Incremental life cycle
Explanation: An incremental life cycle delivers completed, usable pieces of the product in stages, allowing customers to use value early. Iterative focuses on refining the same component, while predictive defers delivery until the end.
