Marius Gensumara found that during a typical period the following numbers of people did not turn up to work at his company in consecutive days:
13, 16, 24, 21, 15, 23, 15, 26, 25, 11,
10, 24, 27, 30, 15, 31, 25, 19, 15, 27
He wanted to improve this and introduced a new scheme of incentives and payments in general. He did not discuss this with the workforce or anyone else, and when he rechecked the numbers of absentees he found these numbers:
31, 29, 27, 30, 26, 28, 38, 34, 40, 25,
29, 34, 33, 30, 28, 26, 41, 45, 30, 28
Marius felt that there was some unhappiness with his new scheme and the way that it had been introduced. So he had various negotiations and agreed another incentive scheme. Now, rechecking the absentees, he found the following numbers each day:
9, 12, 16, 8, 24, 9, 15, 16, 20, 21,
9, 11, 10, 10, 25, 17, 16, 18, 9, 8
