To relate data in 3 dimension with reporting

Dears if you can help or give ideas.

I have about say 100 PRojects to be raised. For each request i have to have data about the time it has taken to complete each phase.

At the end i should also be able to do analysis like what phase took time , which phase was delayed etc..how many projects completed in Jan, Feb, .... etc..

Any ideas welcome please

Thanks in advance
