One is to get people focused on completing a particular task. The other, presumably, is to get them to do the task quickly. One, focus on a task is made a specific goal of work rather than hoped-for byproduct of a deadline. Software Tip I have a long vendor task in my project that has padding built into it, yet they are unlikely to deliver early. For example, if the tasks are guaranteed to be delivered on schedule, no buffering would be needed.
Lets look at an example.
The variability will be 20w 10w or 10w. Now if you are pretty sure that the vendor won't slip by more than 2w, you would set the Duration1 field to 12w. It is typically best to just enter the low-risk durations for tasks that have either a high or low variability. Save yourself some data entry time by using ProChain s default of twice the average duration for most of the tasks. Further Resources ProChain Website.
