11.2. Schedule Audit: Powerful Debugging Tool

Applies to: @RISK 6.x/7.x, Professional and Industrial Editions

I'm using @RISK with a project, but it doesn't seem to be simulating correctly. I've entered my distributions, probabilistic branching, and/or risk register, but the dates aren't varying as I would expect.

When you open the Excel workbook in @RISK, does @RISK then open Microsoft project and open your MPP file in Project? If not, the link between the Excel workbook and the MPP file has been broken and must be re-established. To fix this, see Project Not Linked in @RISK 6.x.

Assuming that the project is linked, there may be a problem in your project itself. Missing predecessor-successor relationships are a common problem, along with some kinds of relationships such as finish-to-finish. Fortunately, you don't have to search for these by examining all your tasks. In @RISK's Project menu, select Schedule Audit. Schedule Audit will present you with a list of issues in your project, identified by task. Each of them is worth looking at carefully, even if you end up rejecting some of them as not applying in your situation. But if you fix all the issues that do apply, you will probably find that your simulation is now behaving much more as expected.
