its Six Steps to Six Sigma and, most notably, a large opp6rtunity for improvement, which translated to an exceptional return on investment. What most people do not remember is that, in addition to its,Six Sigma initiative, Motorola had a secondary initiative to reduce cycle time. But, the cycle time reduction effort did not use the lean tools or structure we know today.

January 2008 • QP 41 During Motorola's first five years of Six Sigma deployment, there was no formal MAIC training, let alone formal lean training. MAIC was the predecessor to today's define, measure, analyze, improve and control (DMAIC) strategy. However, in 1991, Motorola's Six Sigma Research Institute developed and delivered Motorola's very first .BB and MBB training using the

Six Sigma useexpanded beyond the Motorola deployment in the mid-1990s via the Six Sigma Academy. Allied Signal and General Electric (GE) were two of the first organizations to deploy Six Sigma with the primary intent of improving financial performance rather than quality. Other large organizations followed, and once they showed significant return on investment

with the improved Six Sigma model, the revisedmethod gained widespread acclaim.' Several Six Sigma Academy clients made significant contributions to the Six Sigma method: o Allied Signal was the first to implement the Champion infrastructure. o GE added the define phase to the MAIC methodology. ° GE Capital brought a strong focus to voice of the customer (VOC) methods and integrated DMAIC with the business process reengineering (BPR) modeladvocated by Rummler-Brache2 and 3 Michael Hammer. Several divisions of GE as well as other Six Sigma Academy clients, such as Seagate and Toshiba, intro-
