Change impact analysis
Change impact analysis is the process of working out what a proposed change to a requirement will affect before the change is made. By following the links from a requirement to related requirements, designs, code, and tests, a team can see the full ripple of a change and make an informed decision instead of a hopeful one.
What it means
Every change looks small until you trace it. Adjust one requirement and you may touch three others, a handful of design elements, and a set of tests that now need rerunning. Change impact analysis makes that ripple visible up front, so the team can weigh the real cost, effort, and risk of a change rather than discovering them halfway through implementation.
This is where traceability earns its keep. If requirements are linked to their designs and tests, impact analysis is largely a matter of following the links. If they are not, it becomes guesswork and missed connections. Azure DevOps holds the links between work items; tools like Modern Requirements use them to show, at a glance, everything a proposed change would affect.
In practice
A customer asks an automotive supplier to change a communication protocol requirement. Impact analysis traces that requirement to eleven downstream requirements and twenty test cases. What sounded like a quick change is now clearly a significant one, and the supplier can quote and schedule it honestly instead of being surprised later.
