Compression Technique | Myth | Reality |
---|---|---|
Use of overtime |
Work will progress at the same rate on overtime. |
The rate of progress is less on overtime; more mistakes may occur; and prolonged overtime may lead to burnout. |
Adding more resources (i.e., crashing) |
The performance rate will increase due to the added resources. |
It takes time to find the resources; it takes time to get them up to speed; the resources used for the training must come from the existing resources. |
Reducing scope (i.e., needed. Reducing functionality) |
The customer always requests more work than actually needed. |
The customer needs all of the tasks agreed to in the statement of work. |
Outsourcing |
Numerous qualified suppliers exist. |
The quality of the suppliers’ work can damage your reputation; the supplier may go out of business; and the supplier may have limited concern for your scheduled dates. |
Doing series work in parallel |
An activity can start before the previous activity has finished. |
The risks increase and rework becomes expensive because it may involve multiple activities. |
