Six Sigma is a concept with at least three meanings:
  1. 1.

    William B. Smith and Mikel J. Harry (1986) developed Six Sigma at Motorola. The trigger was a specific quality problem in Motorola’s semiconductor division and one customer explicitly required a performance level of 6 sigma.

  2. 2.

    This requirement was the impetus for the development of the DMAIC method and the origin of the name for the whole improvement program (personal message from Motorola).

  3. 3.

    Jack Welsh (1995) at General Electric perfected the implementation, penetration, and sustainable establishment of the improvement program in the whole organization (Fig. 2.1).
