Carl here. ProjHugger is for Microsoft Office Project newbies, enthusiasts, and zealots. I publish new posts every Monday morning, but you can add comments any time. This week’s ProjHugger post continues the “Top 10 problems new (and not so new) Project users have, and what you can do to ease the pain” series, which started like this: #10, #9, #8, #7, #6, #5, #4, #3, and #2.

Problem #1: Forget that the schedule is not the project

You're a project manager who's invested thousands of hours building and maintaining a complex project plan. Sometimes the smartest thing to do is to just throw away the plan.
