How often are management concepts subjected to recalls by the people who invented them? It is hard to think of a single case.
If an industrial product like a car fails the manufacturer pulls it back, tests it and, if necessary, re-equips it. In case manufacturers grow careless, governments run periodic road safety tests. Management concepts, by contrast, operate in poorly regulated environments where failures are often brushed under boardroom or faculty carpets. Yet poor management systems can jeopardize lives in the air, at sea, on roads or in hospitals. They can also put entire businesses and sectors at risk.
