-
Origin of Lean Production
- -based on Toyota Production System; Post-WWII, pioneered in Japan.
- -Kiichiro Toyoda & Taiichi Ohno.
- -Coined by John Krafcik (1991)
-
Lean Production
-Strategy focused on eliminating waste while continuously increasing percentage of value-added time.
-
Muda
- -"waste"
- -any activity, service, or supply that consumes time, money, and other resources.
- -Creates NO value.
-
Kaizen
-continuous incremental improvement.
-
Reasons to embrase Lean (3)
- 1) Patients deserve better
- 2) Employees deserve better
- 3) Nation deserves better
-
Sensei
- -personal trainer with the mastery of a body of knowledge.
- -specialist in Lean production.
-
Two Main Pillars of Lean Production
- 1) Just-in-Time production (JIT)
- 2) Jidoka
-
Just-in-time Production (JIT)
-consistently delivering only the healthcare service that is needed, in just the required amount, where it is needed, and when it is needed.
-
Jidoka
- -Intelligent use of both people & technology with the ability/obligation to stop any process at the first sign of an abnormality.
- -Stop the line.
-
Seven Healthcare Flows
- 1) Flow of pts 5) Flow of info
- 2) Flow of clinicians 6) Flow of equipment
- 3) Flow of meds 7) Flow of process eng.
- 4) Flow of supplies
-
Pull Production
- -system where parts, supplies, info, and services are pulled by internal and external customers exactly when they are needed.
- -when the pt/customer is ready to receive the next service.
-
Effects of Waste
- -Risk for pts
- -Increased costs
- -Decreased satisfaction
-
Seven Wastes of Healthcare
- 1) overproduction 2) Waiting (time on hand)
- 3) Transportation 4) Processing
- 5) Inventory (stock on hand)
- 6) Movement
- 7) Defective Products
-
Waste of Overproduction
- -redundant activities
- -e.g. Park Nicollet Health Svcs (PNHS) - excessive printing reports; VMMC - repetitive questioning --> EMR.
-
Value Stream
-the specific activities required to provide a specific service to the pt.
-
Waste of Time on Hand (waiting)
- -waiting to see physician, early admissions for afternoon procedures, staff waiting for meetings.
- -e.g. VMMC - 20min wait time, improved; PNHS, decrease lead time from 2hrs to 9min.
-
Standard Work
-a prescribed repeatable sequence of steps/actions that balances people's work to takt time.
-
Takt Time
- -production time aligned with the rate of demand.
- -time it should take to provide a service to one pt based on the overall rate of demand from all pts.
-
Waste of Stock on Hand (Inventory)
- -inventory that builds up and requires disposal; takes time and energy to remove/move.
- -e.g. PNHS, implement Kanban to supply items that were high cost, low use so as not to over-stock; VMMC, wasted time moving supplies form closet to POU -- only stock in room at POU.
-
Kanban
- -a way of automatically signaling when new parts, supplies, or services are needed.
- -"sign," sign board, billboard, doorplate, poster, or card.
-
Rapid Process Improvement Workshop
- -aka Kaizen event.
- -team of people who do the work, fully engaged in a rigorous and disciplined 5-day process, using the tools of Lean to achieve immediate results in the elimination of waste.
-
Waste of Movement
- -lg. part of budget of for wages (70%), thus time is valuable -- optimize use of employees' time.
- -mostly staff trying to find equipment, info or attending meetings farther from dept.
- -e.g. PNHS - Rad techs moving equipment; VMMC - decreased walk time for RNs and PCTs.
-
Walk Time
-time spent walking from one location to another.
-
Cell
work area (VMMC example)
-
Waste of Defective Products
- -errors in charting/documentation; VMMC implement PSAs (patient safety alerts).
- -e.g. PNHS - created pt. tracking system, for pre-op pts; andon utilization.
-
Andon
- -a visual control device, usually a light, that alerts supervisors to factory floor needs or problems.
- -green, yellow, red light system for example.
-
Waste in Transportation
- -movement of supplies, files, equipment
- -e.g. PNHS - vans transferring mail, files, and films; upgraded EMR. VMMC - decreased automated shipment of files not needed (neurology clinic).
-
Waste in Processing
- -unnecessary tests, repeatedly logging the same data.
- -e.g. VMMC - eliminate MRIs for non-surgical back pain pts. PNHS - eating d/o institute, meet with psych before entering EDI for further eval.
-
Global Production System or the Lean House
-a generic and graphic representation of the Toyota Production System (Lean).
-
Components of Lean House
- -Foundation = goal of lean (eliminate muda).
- -Floor = leveled production (heijunka).
- -Columns supporting roof = JIT production & Jidoka.
- -Columns within house = Left (people, materials, & machines), Middle (standard work, kanban, & andon), Right (takt time, one-piece flow, & pull production).
-
Columns within Lean House
- LEFT = Necessary resources
- MIDDLE = Lean Methods
- RIGHT = Outputs
-
Heijunka
-scheduling products and services in such a way as to eliminate bottlenecks and maximize throughput.
-
Stop the Line
-where any staff member can stop any process or procedure if that staff member believes proceeding would adversely affect pt safety or negatively impact efficient operations.
-
Key Principles within the Lean House (3)
- 1) Takt-time-paced Production.
- 2) One-piece Flow
- 3) Pull Production
-
Takt-time-paced Production
- -providing services/products at the overall rate of demand from the pts.
- -e.g. total hrs/mins in a work day for a # of pts.
-
One-piece Flow
- -all equipment, other supplies, and information are physically grouped together to enable one person to perform all the steps necessary to complete a process or action.
- -opposite of batching work.
-
Pull Production
-system where parts, supplies, info, and services are pulled by internal and external customers exactly when they are needed.-when the pt/customer is ready to receive the next service.
-
Resources
- 1) people
- 2) materials
- 3) machines
-
Appropriate & Efficient Use of People's Skills
- Method: standard work; prescribed, repeatable sequence of steps/actions.
- Principal output: take-time production.
-
Appropriate & Minimal Use of Materials
- Method: standard work-in-process (SWIP) and kanban.
- Principal output: work with takt-time management to enable one-piece flow.
-
Appropriate & Optimal Use of Machines
- Method: operational availability/andon.
- Principal output: pull production.
-
Operational Availability
-the availability of healthcare equipment when needed.
-
Standard work-in-process
-the amount of work-in-process inventory on the floor to provide pt care for the day.
-
Standard Work Sheet
- -a document identifying the steps necessary to complete a task, who should perform each step, and the reasonable (repeatable) amount of time to complete each step.
- -e.g. PNHS & blood pressure work sheet.
-
Three-legged Stool of Standard Operations
Made up of standard work, takt time, and standard work-in-process.
-
5S Process to Organize the Workplace
- 1) Sort - the unnecessary
- 2) Simplify - organize
- 3) Sweep - identify unsafe conditions
- 4) Standardize - define and communicate
- 5) Self-discipline - hold everyone to same standard
-
Value Stream Map
-a pictorial representation of the steps in a value system, either as a current or future (desired) state.
-
Preparation for Lean Action Plan
- 1) get rid of competing strategies
- 2) Find outside Sensei
- 3) No shorter than 5 yr contract
- 4) Develop a sense of urgency
-
Elements of Action Plan
- 1) Identify your business & its scope.
- 2) Est. a Kaizen Promotion Office & Kaizen Operations Team.
- 3) Begin with a model line an inch wide and a mile deep.
- 4) Implement your waste-elimination strategy via workplace Kaizen events & Kaikaku.
- 5) Map value streams/disrupt organization.
- 6) Focus on cutting lead time/cycle time.
- 7) Reorganize by service lines & value streams, flatten the organization.
- 8) Develop internal leaders.
- 9) Deal with excess people at outset.
- 10) Implement world-class management system.
- 11) Link pay to value creation and elimination of defects.
-
Lean Accounting
- -combination of Lean and budgeting ideas from Jeremy Hope & Robin Fraser.
- -based on key performance indicators.
- -e.g. PNHS - cost per unit of svc, and units of svc per full-time equivalent.
-
Kaizen Promotion Office (KPO)
- -develop lean action plan.
- -work with managers & CEO on day-to-day basis.
- -edu/development of Lean leaders.
- -2-5% of work force.
-
Kaizen Operations Teams (KOTs)
- -for each major svc. line.
- -PHNS, each ran by Lean leader having completed 18mo. training in lean/kaizen.
-
3P
- production preparation process.
-
Greenfield
- a new facility or process.
-
Brownfield
- an established facility or process.
-
Cycle time
- The amount of time it takes to complete a task or process.
-
World-Class Management System
- 1) Daily management, management by policy (MBP), determine improvement priorities.
- 2) MBP - opposite of management by objective. How goals are determined, plans made to achieve goals, and ensure progress.
- 3) Cross functional management - major management system for implementing breakthrough improvements across organizational lines.
-
Management by Policy (MBP)
- -a catch-ball process. Meaning where goals are proposed and discussed by people all the way down and up the chain of command.
- -aka hoshin kanri
-
Top Measures
- QCDSM
- -quality, cost, delivery, safety and morale.
-
Gemba
-where the work gets done, e.g. the factory floor or hospital floor.
