  1. 1. KAIZEN
  2. 2. 5 Lean Principles • Define value from the customer perspective • Identify the value stream • Optimize flow • Pull from the customer • Drive toward perfection
  3. 3. What Is Waste? • Waste is everything we do that takes time and adds cost, but no value in the eyes of the customer.
  4. 4. What is Time? • The most difficult waste to identify • The 3 types of time o Value-Added Time – performing essential tasks for which the customer is willing to pay o Type 1 NVA (Enabler) - performing a task that the customer doesn’t want but is currently necessary o Type 2 NVA (Waste) – performing a task that the customer doesn’t want and is not necessary
  5. 5. 7 types of Waste 1) Overproducing 2) Waiting 3) Moving 4) Process Downtime 5) Excess Inventory 6) Unnecessary Motion 7) Scrap
  6. 6. Kaizen as a Tool for Continuous Improvement • Creativity before capital • Bias for action • Total associate involvement • Never satisfied with the “Current State”
  7. 7. A Kaizen Definition To continuously improve or take actions to improve. A team activity that is preplanned to improve a baseline measurement. At a minimum the team will: – meet to discuss the measurements that will be improved, – plan the time period when the improvements will be made, – carry out the actions, steps and activities that will establish the baseline and then improve the measure – record the results on the Lean Status Report – reward and/or recognize the team for the improvements made – schedule the next kaizen event
  8. 8. 2 Kaizen Levels • Flow Kaizen – Focus is the overall value stream – Directed by value stream manager(s) – Creating mfg. cells, 5S, • Process Kaizen – Focus is on the individual process – Directed by the work teams and team leaders – Set up reduction, standard work, 5S
  9. 9. 10 Steps for Kaizen Success • Notify team members of planned Kaizen event • Set planning meeting, complete Area Profile, and CSVSM • Review team make up. Are the right skills on hand? • No distractions to the team during the event – Assign a substitute! • Set start time and end times for event • Start on time • Take Action - Team is empowered to make positive changes and enforce • Be meticulous about the execution, be alert to safety issues, clean everything; even at the borders • No “Doggy Bag”. Add unfinished or open actions to kaizen newspaper or work plan • Celebrate, Reward and/or Recognize team accomplishments
