I would love a copy of the guidelines you've been sending out!
Here's some additional ones as a thank you for your trouble, in no particular order:
1) If you are sorting the data by one or more columns, put the columns you are sorting by on the left.
(Ok, for Arabic, maybe it should be on the right.
This isn't a hard and fast rule, there are valid exceptions to it, but it does make things easier to comprehend right up front.
2) Use the same label for the same data item on all reports unless forced (by layout constraints) to do otherwise. (And then be consistent with the short version of the label when you need to use it again!)
3) If the report has parameters, the selected parameter values should be visible in the report output. This way, someone who picks up a copy of the report knows exactly what portion of the data was included on the report.
4) If you have a numeric value that people might want to add up, don't put anything else above or below it in the same column. Makes it very hard to do that.
5) I view a report as the answer to a question. Make sure you understand the question! Make sure you understand what information is needed in order to take action on a problem revealed by the report - and try to make sure that information - or at least the full key to it - is on the report.
