As Peter Drucker wrote: “In knowledge work . . . the task is not given; it has to be determined. ‘What are the expected results from this work?’ is . . . the key question in making knowledge workers productive. And it is a question that demands risky decisions. There is usually no right answer; there are choices instead. And results have to be clearly specified, if productivity is to be achieved.”*
