Dashboard Advice Sought: How Would You Improve This?

There are many configurations for dashboards, so there is not a "one-size-fits-all" - often common elements, but custom approaches to implementation.

I assume your real workbook is dynamic and not static (which is one of the main points of a dashboard).

The trick is getting the right balance of information without an overly-busy display.
That being said, I would probably opt for reducing the number of departments to one for each directorate and using a drop down list to select which department to view (relative to each directorate).

By reducing the departments displayed and making them dynamically selectable, you would free up some display space for other info.

Would be nice to have dynamic charts that:
1. Allow comparisons of departments within a directorate
2. Summarize income streams by department to show trends and allow for comparisons

Your sample workbook doesn't contain any date/time related data, but this might be a useful addition and should allow for dynamic selection of date ranges, assuming your raw data contains such.
