Lean has a very good tool set; however, it is not a business management system. To better address the challenges of the day, organizations need an effective business management system that integrates lean tools with predictive scorecards and analytical/innovative strategies so that undertaken process improvement efforts have whole-enterprise benefits. The Integrated Enterprise Excellence1 (IEE) business management system, which is illustrated in Figure 1, accomplishes this organizational objective. In Lean Six Sigma, improvement projects are to follow a define-measure-analyze-improve-control (DMAIC) roadmap. Within the IEE system, there are two DMAIC roadmaps: Project DMAIC (P-DMAIC) and Enterprise process DMAIC (E-DMAIC). This article discusses how these roadmaps are used to integrate Lean tools into the business management system.
