Accompa makes performing Impact Analysis quite simple.

Here are the steps to perform impact analysis for a requirement:

1. Go to "Requirement Details" page of the desired requirement. (How do I do this?)
2. Click Actions at the top-right of the page, and select Perform Impact Analysis from the menu.
3. The resulting page will display all the items that are impacted by a change to this requirement.

Performing impact analysis for other items - such as a "Feature" or a "Use Case" - is similar.

Applying Filters:

Viewing all items that are impacted by a change to an item can create a lot of noise, especially when you're only interested in the impact on items belonging to specific project(s).

Accompa enables you to apply filters to eliminate such noise, and achieve your objective:

1. Perform the steps described above.
2. Click Filter Results >> link at the top of the Impact Analysis page.
3. Select one or more desired SmartViews whose "Filter Criteria" you'd like to apply.
4. Click "Apply Filter" button.
5. The resulting page will display the filtered results of Impact Analysis (i.e. results filtered using the filter criteria defined in the selected views).
6. You can remove filters using the "Reset Filter" button. You can hide the 'Filters" section by clicking on Filter Results >> link again.
