On Requirements and Estimates

“What obstacles do project managers face to successful completion of an Information Technology project?”

Technology Management; Technology Infrastructure

I agree that most project has some unique obstabcles, all project that i have worked with or been aware of have had 3 common problems

1. Incomplete requirements or lack of visibility to full requirements
2. Poor estimation of effort
3. Scope creep

MüTō Observation:

These are three very common problems. I often find that a project manager's inability to communicate clearly, encourage proper motivation, and hold others accountable is at the core of all three of the problems you listed.
