Agenda  Abstract/Introduction  Method  Tools  Thirteen LSS Tools  Conclusions  Future Research  Footnotes

Abstract/Introduction  Abstract  Introduction Lean and Six Sigma –Lean –Six Sigma Perspective SEDC & DoD Track Tie Recent Article

Method  Comparative Analysis INCOSE SE Handbook vs. ASQ and MIT LSS Tools = Processes, Methods, or Techniques Shared, Similar, Generic Tools

Tools  Shared- QFD, IPDTs  Similar- TPM/Control Charts  Generic include many and non Technical- Statistical Tools

Pareto’s Law / Poka Yoke/ RACI & LRC  Pareto’s Law Concept- 80/20 Usage- Prioritize Risk, Requirements, Verification, Trade studies  Poka Yoke Concept- Design in for happy path Usage- Detailed software design  RACI and LRC Concept- Role clarity Usage – SE planning

Con. Res. Diag. / Error Proof./ Toyota  Conflict Resolution Diagram Concept- Conflict Usage- Trade studies  Error Proofing Concept- Design out errors in process Usage- Detailed design  Toyota Production System Concept- Reduce waste Usage – Flexibility

Future Reality Diagram / LPI/ TOC  Future Reality Diagram Concept- Planning for Change Usage- Upgrades & Future Increments  LPI (Lean Performance Indicator) Concept- Metrics for effectiveness Usage- Incentives  TOC (Theory Of Constraints) Concept- Resources for Logistics, Performance, and Logic Usage- Trade studies

Quick Change. / Kanban / Takt Time  Quick Changeover Concept- Adaptable processes Usage- Requirements and Design flexibility  Kanban Concept- Just In Time Usage- Design and Planning processes  Takt Time Concept- Balance Process designs for schedule Usage- Design and Planning process

Perspective  Perspective Concept- The Blind Men and The Elephant Usage – Expanding Lessons Learned and synergy between disciplines

Conclusion & Future Research  Conclusions SE efforts improve use of 13 LSS Tools SEs synergy by know the differences in terms & use  Future Research Validate Improve Expand
