There are two aspects to reporting: reporting on status, and reporting on results. Small Improvements excels at reporting the status of your performance reviews, your 360s, and managing your objectives. As an administrator, you will always know what's happening, who's slacking, and who to nudge into action.
If you're using the 2D graph to chart perceived results and behavior in performance assessments, then you can use the combined graph for your entire organization as a visual tool to compare teams or pick out discrepancies between self-assessments and manager assessments. You can also always find out what your compliance/completeness rates are by selecting "All performance reviews" from the Admin drop-down menu.
You can also export the ratings that we track to Excel for further processing (there are "export"-buttons at the end of the overview admins screens). We don't (yet) report on rating distributions or ratings over time. We will be adding more ratings reports in time, but it's not our core focus. Our product is at its core about helping employees improve. Some of our clients even disable all ratings and focus only on the content of reviews.
