6 Lean Thinking The core idea is to maximize customer value while minimizing waste. Simply, lean means creating more value for customers with fewer resources. »Lean Enterprise Institute, –Guiding Principles Purpose Process People Source: http://www.lean.org/WhatsLean/Principles.cfm

7 Lean Thinking Ford, Highland Park Michigan, 1913 End to end integrated production process Source: http://www.lean.org/WhatsLean/History.cfm Toyoda Weaving, Toyota Motor Company, 1930s / 1940s Self monitoring machines (Jidoka) Just-in-time (Kanban) Womack / Jones, 1990’s Lean Thinking Value / Value Steam / Flow / Pull / Perfection

8 Lean Thinking - JIT Lean Thinking – JIT (Just-in-Time) –Response to variation –In Supply chains – parts are available: –at the time they are needed –in the right quantity –in the right condition. –In service systems – service providers are available: –At the time they are needed –Without undue delay (queuing) –With the right skills In response to a demand signal ( 看板 Kanban ) In response to demand
9
9 Lean Thinking - Jidoka Jidoka (Autonomation) –Automation with a human touch 4 Steps –Detect the abnormality (problem visibility) –Stop (learn how to wait). –Fix or correct the immediate condition. –Investigate the root cause and install a countermeasure.

10 Value It must transform the product or service. The customer must be willing to “pay” for it. It must be done correctly the first time. Waste Mura or waste due to variation Muri or waste due to overburdening or stressing the people, equipment or system Muda also known as the “seven forms of waste” Source: http://www.lean.org/Coomon/lexiconterm.aspx
11
11 Overburdening (Muri) Theory of Constraints 4 Focusing steps 1.Identify the constraint usually a bottleneck 2.Exploit the constraint run the constrained step efficiently 3.Subordinate all other processes to above Re-balance the work 4.Elevate the constraint system / capacity changes
12
12 Variation / Unevenness (Mura) 1.Understanding Variation 2. Planning for Variation
13
13 Six Sigma and Variation Six Sigma – Improves results by finding and eliminating sources of defects and reducing variation Variation –“If I could reduce my message to management to just a few words, I’d say it all has to do with reducing variation.” Attributed to W Edwards Deming

14 Waste (Muda) OVERPRODUCTION WAITING DEFECTS PROCESS INEFFICIENCY TRANSPORTATION INVENTORY MOTION MISUSED TALENT Drawing too many samples, Extra tests Waiting for a doctor, procedure, bed, test result, or discharge Medication Errors, Wrong Patient, Wrong Procedures, missing information, redraws, poor clinical outcomes Multiple Bed Moves, Multiple tests, excessive paper work Moving samples, specimens, patients, or equipment No empowerment, unenlightened management, poor hiring practices, lack of training, scope of pracice Searching for patients, medication, charts, gathering supplies Patients waiting, inventory of supplies, out-of-date supplies, stock outs.

25 Creating the Future State 8 Future State Questions 1.What is the takt time? 2.Will you build to a finished goods supermarket or directly to shipping? 3.Where can you use continuous flow? 4.Where will you use pull systems? 5.What single point will be the pacemaker where you will schedule work? 6.How will you level production mix at the pacemaker? 7.What increment of work will you release? 8.What improvements will be necessary?
26
26 Future State Map Step 1, Mark your future state ideas on your current state map 2. Build to shipping 3. Flow 4. Supermarket to exam room supplies 5. Pacemaker 6. Mix 7. Ptich 1. Takt = 9 Minutes

Ptich Step 2 (Future State Q8, Document the improvements necessary) Reduce C/O time to 1 minutes Nurse to assist with patient / physicain change over Step 3 Calculate the new lead time Increase nurse uptime to 100% 1 Minute _________ 1. Takt = 9 Minutes 4 Minutes _________ 1 Minutes _________ 28 Minutes _________

33 Lean and Learning “Why not make the work easier and more interesting so that people do not have to sweat? The Toyota style is not to create results by working hard. It is a system that says there is no limit to people’s creativity. People don’t go to Toyota to ‘work’ they go there to ‘think’” - Taiichi Ohno - 10. Rother
