Developing a Rough Order of Magnitude (ROM) estimate will involve both subject matter experts and project managers. The “Rough Order of Magnitude” estimate should have at least a (plus or minus) 50% accuracy. The variance may not always be in this range but it should be the target for a useful “ballpark” estimate at a Read more about A Guide to Developing a ROM Estimate[…]
Purpose: A ROM tool that allows for effective IT project estimation. This Rough Order of Magnitude Template consists of 4 worksheets (Summary, Initiation, Plan/Design, & Execute) and incorporates Total Adjusted Function Point methodology. The Actual Order of Magnitude (AOM) is realized upon project completion. This ROM Template is invaluable for project managers.
