  2. Lean 6-Sigma Approach to Field Service Logistics • Goal: continuous process improvement • Problem Definition: Provide on-going research, consultation, design, and assessment support to the FAA in identifying & implementing best practices for “lean 6-sigma” initiatives. • Identify and prioritize projects • Assist in projects where expertise matches

  3. Lean 6-Sigma Approach to Field Service Logistics • Value Stream: “The set of activities that convert customer needs into delivered products and services.” • Project: “An idea that can be addressed by a Lean Six Sigma project team and largely meets established screening criteria.” • Process Cycle Efficiency: “A key Lean Six Sigma metric, measured as the amount of valued-added time in a process divided by the total lead time.” Source: George, M. L., Lean Six Sigma: Combining Six Sigma Quality with Lean Speed, McGraw-Hill, 2002, pp. 129-130.

  10. Lean 6-Sigma Approach to Field Service Logistics Cost estimating and forecasting methodologies • Alternative methodologies • Reliability-based • Demand-based • Cost-based • Results by cost-based approach • Product families (e.g., radar) • 80-20 (Pareto) rule • Product management groups (value/demand pattern) • Forecast segmentation (short-term v. long-term)
