The effects of multitasking someones time.
Here is the basic effect of multitasking someones time, all but the last work stream is late. This concept does not take into account the increased marshaling between task types so this means the last work stream is also invariably late.

Correct. Two sequential 2 week effort tasks are more likely to take 5 weeks effort when run in parallel. It is simple to understand, but the IT industry keeps getting sucked into believing it can 'matrix manage' efficiently, running multiple projects in paralell, and yet avoid waste. The problem is easy to understand, the solution is easy to understand, however getting senior management to understand is the hard bit as often they do not want to understand because the truth is hard to swallow.
