My Stickyminds column this month deals with choosing when to start and end project overtime, “When Should You Start Project Overtime?”
Frank Patrick has already chimed in with one of the common causes of overtime, multi-tasking. See Multi-tasking Multiplies Lead Time
Also see these blog entries from Esther Derby and Hal Macomber. A note: I think Esther, Frank, Hal, and I blogged bunches of entries about multi-tasking in March, which is why I referenced Esther's March archive.
Please do read the Stickyminds column, and post your comments. The more, the merrier.
