M&TE CAL LAB "Use of A3 during Problem Solving" Instruction
Application of A3 in the Nuclear Industry “A3 Problem Solving Method” Pilot Team: M&TE Calibration LabTeam Sensei: Todd McCannTeam: Cal Lab Manager, Cal Lab Supervisor and 3 Lab TechniciansTeaching: A3 Proposal, Status and Final Summary, ISHIKAWA,Standardized Work Sheets, Nemawashi, Jishuken, Hansei,Hoken Development, Yokoten, Makigami, PDCA, SDCA
Core Foundational Practices of ToyotaFocus: Teaching M&TE Lab the discipline of A3 A3 Background JISHUKEN Translation: A Theme of Self Study The self study improvement projects are linked to business goals, driven and performed by teams of managers. Use A3 for recording data, describing problem, problem solving, sharing of work efforts with others (Note: Genchi Genbutsu = Go See at the Gemba the Materials, Machines and Environment where work is performed for Yourself. Primary Activity for Jishuken) + YOKOTEN Translation: Across everywhere. Horizontal Deployment How plant related activities and/or countermeasures are communicated Work Groups GO SEE other’s improvements NOT Best Practice or Benchmark sharing, Better Yet, Problem Solving Sharing And COPYING of IDEAS Most Often Applied PEER TO PEER No need to Re-invent the Wheel share your ideas with others!
Team Learning: 3 types of A3-T• Proposal NO OVERHEAD PROJECTORS ALLOWED ALL WHITE BOARD WORK• Status• Final Report HIGH TOUCH > NO TECH > LOW TECH With Many Examples
