4Matrix is the Holy Grail for Data Managers! Yes I did say that. I hadn't noticed that I had got so carried away! It is a testament to the quality of the software (and it can only get better), that it provides the majority of the important analysis that data managers need to make, and with 4Matrix we can do it on a regular basis with very little outlay in terms of cost or effort. This is a far cry from messing around with spreadsheets and formulas.
