1. Rapid Improvement Events Converting Philosophy to Action Original slides by Doug Fingles - MERC

2. Lean Review 5 Principles Value Value Stream Flow Pull Perfection Tools Value Stream Analysis 6S Cells Standard Work Rapid Improvement Events 8 Wastes Injuries Defects Inventory Overproduction Waiting time Motion Transportation Processing

3. Definition A dedicated group spending 3 to 5 days improving a focused area or process that is usually tied to a Value Stream Analysis.

4. Rapid Improvement Events A seven week cycle of preparation, action, and follow-up to improve one area or fix a problem People: work leaders, mechanics, workers, supervisor, and a Lean Change Agent Led by the supervisor or work leader Guided by the Lean Change Agent

5. 7 week Cycle 3 Weeks out: Pick the team Measurements Deliverables 2 Weeks out: Get workcenter history Communicate Plan 1 Week out: Define boundaries Communicate Review

6. 7 Week Cycle Week of the Event: Day 1 Current conditions Day 2 Make the changes Day 3 Run the new process Day 4 Create Standard Work Day 5 Outbrief

7. 7 Week Cycle 1 st Week After: All or nothing—be relentless on Standard Work, 6S, Inventory, etc. See and fix problems 2 nd Week After: Keep up Standard Work, 6S, Inventory See and fix problems 3 rd Week After: Shift to sustainment, make the new the standard practice Continue to see and fix problems

8. Projector Screen Co. Makes pull-down projector screens Small business, less than 10 people One shop, original owner Best product/cheapest “We made the big time!” Orders are up Coming in faster than can produce Customers are unhappy at delay(s)

9. Preparation Previous Weeks: 3 Weeks History Select team 2 Weeks Communicate Productivity numbers Determine targets 1 Week Train Communicate Results: Takt Time (pace, or timing) Team in place Place for Event Team Trained Productivity numbers are known (output, quality, delivery)

10. Preparation Previous 3 weeks: History—small business growing rapidly, experiencing long lead times and customers wanting quicker delivery You are our team—handpicked from the floor, supervision and a Lean Change Agent We’ve communicated our need for change We have our productivity numbers Targets: Produce 135 per day, maintain quality, and find space for new products

11. Day One Tasks Build a Spaghetti Diagram See the flow of people and parts Build a Bar Chart Show the workload per person/station Time the operations From when a part is started to finish Individual stations Measure Output Floor space

12. Define the Boundaries What process(es) will you map? What can we not screw up? Inputs Outputs Who are the customers For the product For the process Top 2 or 3 measurements

17. The Numbers Takt Time = Time Avail/Customer Demand 8 hr shift – 20 min for breaks, 10 min 6S, 5 min TPM = 445 min Demand = 135 screens per day 445/135 = 3.3 min per screen Process time = 18 min per screen, or 25 per day (445/18) 3 Workers produce 75 screens per shift, or 60 below demand 3.5 hours overtime = 36 screens, still 24 shy of daily demand 24X5 days = 120, or a full Saturday and half of Sunday to fill all the orders

18. Day Two Tasks Eliminate the waste found on Day 1 What waste(s)? Create a cell or make changes to the cell What would it look like? Tools: Paper dolls Cardboard cut outs of stations Simulations Bar Chart Spaghetti Diagram Run the new setup at least once Create basic Production Control Board

21. The New Numbers Takt Time = Time Avail/Customer Demand 8 hr shift – 20 min for breaks, 10 min 6S, 5 min TPM = 445 min Demand = 135 screens per day 445/135 = 3.3 min per screen Manual Cycle Time = 10 min per screen, or 44.5 per day (445/10) 3 Workers can produce 133 screens per shift, or 2 below demand 20 min overtime = 2 screens

22. Day Three Compare new measures against targets Run the cell Be prepared for problems Have someone assigned to each worker Watch for Flow Are any parts moving backwards or sideways? Are tasks and positions for workers helping flow? Is there a Pull system in the cell? Corral the extra inventory-lock it up

23. RIE Screen Projectors Compare measurements against the targets Stay with the Cell, look for Standard WIP, Standard Work sequence Review Production Control Board Tools: Build/use Standard Work Combination Sheet Takt time New Spaghetti Diagram Bar Chart

24. Day Five Outbrief Recognize Team Members Use visuals/tours to show progress Begin the follow up actions

25. Follow Up 1 st Week After All or Nothing Supervisor monitor cell on hourly basis Use Production Control Board Keep excess inventory locked up Solve problems Supervisor/Leaders take responsibility 2 nd Week After Don’t Relax Use Production Control Board Focus on Standard Work Supervisor/Leaders solve problems 3 rd Week After Sustain Use Production Control Board Use Standard Work Supervisor/Leaders solve problems
