Incremental Design Guide and Exam Tips

Why it's important: Incremental Design is a key part of many Agile methodologies including Test Driven Development (TDD) and it is frequently focused on in the PMI-ACP examination. Understanding the logic and applications behind this design approach can not only enhance your project management skills but also boost your exam performance.
What it is: Incremental Design is an approach where the system is designed, implemented and tested incrementally (a little more is added each time) until the product is finished. It involves both development and maintenance.
How it works: It starts with a simple implementation of a subset of the software requirements and iteratively enhances the evolving versions until the full system is Implemented. The system is defined as a collection of cohesive functionalities and can be incrementally built in any order.
Answering Questions on Incremental Design: When faced with an exam question, read it carefully and look for keywords or phrases that indicate it's related to Incremental Design, such as 'iterative', 'incremental', 'evolving versions', 'subset of software requirements'.
Exam Tips: Make sure you understand the principles and applications of Incremental Design. Practice with actual exam questions if possible. Remember that in Incremental Design, functionality can be developed, tested, and delivered in any order and each cycle involves a team working through a full software development cycle.
