A fit-gap analysis is the process of comparing business requirements with the capabilities of the proposed or existing solution to identify gaps.
It is critical because it helps solution architects:
Identify which requirements are already met (fit)
Avoid unnecessary customizations
Understand where configuration, customization, or alternate solutions are required
Control project scope, cost, and timeline
In Dynamics 365, where rich out-of-the-box (OOB) functionality exists, fit-gap analysis ensures that existing features are reused rather than rebuilt.
First read the answer fully, then try to explain it in your own words. After that, open a few related questions and compare the concepts. This method helps you remember the topic for a longer time and improves exam preparation.
