Change Impact

From Zanecorpwiki

The first question: "Is this a change in the model or just the implementation?" Model changes imply implementation changes, of courses, and tend to be more disruptive. Assumptions in bordering modules are more likely to need to be revisited, processes and flow may need to be reworked, etc.

On the other hand, implementation only changes are much less likely to be disruptive. Ideally, these changes just require addition of code, like an extra 'if-else' statement. When refactoring is required, it's generally more limited.
