Complexity of that 10 month project could define the timeframe needed. Two months sounds reasonable but politics and complexity could change that. significantly. Do you have a database of past efforts or could you create one. We had a large database of such things from past history, realizing that exceptions and variations will occur Perhaps you could go back and do that or find that information on the IEEE Computer, ACM, or PMI web sites. I think it also depends upon where you are in the planning cycle of your corporate year. Good luck.
