look at what business week said about the discovery of Post-It notes:
For a long time, 3M had allowed researchers to spend years testing products. Consider, for example, the Post-it note. Its inventor, Art Fry, a 3M scientist who's now retired, and others fiddled with the idea for several years before the product went into full production in 1980. Early during the Six Sigma effort, after a meeting at which technical employees were briefed on the new process, "we all came to the conclusion that there was no way in the world that anything like a Post-it note would ever emerge from this new system ," says Michael Mucci, who worked at 3M for 27 years before his dismissal in 2004. (Mucci has alleged in a class action that 3M engaged in age discrimination; the company says the claims are without merit.)
