Best Practice : Manufacturing Excellence Model
Raytheon’s Integrated Air Defense Center facility demonstrated the benefit of using an existing tool for measuring continuous improvement by implementing a modified version of the Manufacturing Excellence Model tool set currently used by its Raytheon Missile Systems’ Tucson facility to create an effective business diagnostic for use in the Lean Deployment Process.
Raytheon’s Integrated Defense Systems’ (IDS’) Integrated Air Defense Center (IADC) facility has implemented a process for measuring continuous improvement based on the Manufacturing Excellence Model (MEM) tool set used by its Raytheon Missile Systems (RMS) Tucson facility to form a business diagnostic to track progress through the Lean Deployment Process using a benchmark/baseline. Raytheon IDS modified Tucson’s existing tool set to remove the ambiguity of a “no common maturity index” for rating criteria. By incorporating multiple sources (Figure 2-6), the IADCr re-established rating criteria for each functional area at its facility to create an effective business diagnostic tool that would best fit Andover’s needs.
By taking an existing Raytheon model and using it in an innovative way to baseline the Lean Deployment Process, the Andover facility created an effective tool for measuring continuous improvement. The new MEM tool has 20 major criteria items for assessing current levels of lean maturity that are grouped into six major categories (Table 2- 1).
Raytheon demonstrated that by taking an existing internal process from another facility and merging it with external practices, they were able to arrive at an innovative approach to performing a business diagnostic for use in the Lean Deployment Process.
