One of the recommendations well described in the previous commented paper:
“…If the worker beleives an activity’s duration is reasonable even if it’s optimistic and the person remains properly motivated, they will change their behaviour to achieve the strech target and consequently change the outcome…”
About the role of the schedule in a project:
“The problem with expecting project scheduling to produce an accurate forecast of the future is it is impossible to accurately forecast or control the future. The solution to effective project delivery lies in a different direction; using the schedule to influence the future actions and decisions of people.”
The paragraph called “the role of the Schedule in a 21C Project” is very valuable.
