Guide for Incremental Development: Importance, Functioning, and Exam Tips

Incremental Development is a critical aspect of Scrum methodology and customer-centric design.

What is Incremental Development?
Incremental Development is a process in which the product is designed, implemented and tested in separate, manageable parts. Instead of delivering it all at once, the project is broken into discrete pieces, or 'increments'. Each increment delivers a part of the functionality in its entirety.

Why is Incremental Development important?
It reduces the risk of project failure because each increment is less complex than the entire project. Immediate feedback can be obtained, ensuring that any issues are identified and resolved before the whole system is built. It also provides value to customers early on and frequently.

How does Incremental Development work?
The product's development process is partitioned into smaller parts, each delivering a feature or functionality of the end product. These parts are built and delivered in iterations, allowing the team to adjust its plans and progress based on the feedback received.
