If it is research and development, it goes www.erpvn.net up generally to around ±10 to 15 percent. If the project involves pure research, the sky is the limit. Imagine, for example, that you work for a pharmaceutical company, and your boss says, “Tell me how long it will take and how much it will cost for you to discover and develop a cure for AIDS.” For every organization, you will have to develop a sense of acceptable tolerances through experience. Then you start trying to reduce them. All progress is an attempt to reduce variation in what we do. We will never reduce variation to zero without eliminating the process altogether, but zero has to be the target. EXERCISE Figure 8-9 shows earned value figures for a project.

They assemble a team, give the members their instructions, and sit back and watch the project self-destruct. Then they question whether there might have been some flaw in the tools.
