The Lean Enterprise All About KaizenLean FoundationsContinuous Improvement Training
Another methodology: KaizenWithin the Continuous Improvement tools arena, perhaps none is more critical than Kaizen events. While other lean tools may stand alone, Kaizens seek to change culture and processes through the utilization of many of the lean enterprise principlesKaizens seek small daily improvements resulting in large yearly savingsCompared to a large-scale DMAIC project, Kaizens focus on short-term blitzes to make immediate impact and change (change for the better) The process of leading a Kaizen however, follows the DMAIC format
Learning ObjectiveThis section seeks to standardize the process of Kaizens in an attempt to provide useful tools allowing first-time facilitators to hit the ground running with a project of their own. One important concept is to start small and tackle the more complex problems at a later date - once momentum is built and the Kaizen process has been understoodSome of the tools include a Kaizen Schedule, Kaizen Area Improvement Sheet, 7W and 5S forms, Area Action Form, Prioritization Matrix, and a Problem Record Sheet (These are embedded in the presentation and located in forms section )

Overview What is Kaizen ?
Kai = ChangeZen = Good (for the Better)
The Basic Philosophy Is to Involve All Employees in Small, Daily Improvements within their Work Areas.
Overview Benefits of Small Daily Improvements can Add Up
20% Improvement(One Time)20%(One Time)1/10 of 1%(Every Day)1/10 x 250 Workdays25% ImprovementPer Year

OverviewWhat is a Kaizen event?A Kaizen event is a planned event (2 - 5 days) of intense improvement activities directed at specific areas of the business toward a larger goalKaizen events are essentially narrow-focused, short-term DMAIC projects. These can ALSO be done as part of any Lean, BB or GB projectA Kaizen event is a cycle of improvement
How do I do a Kaizen event ?You do a Kaizen the same way as a DMAIC project and using PDCA as your guide
Cycle of Continual Improvement Kaizens follow a continuing cycle of improvement S = Study the change, assure it is stable then, improve again!

Benefits of a KaizenTeamworkEveryone is able to participate and make improvementsNo one individual, but a team, make the improvementsCommunicationImproved relations between associates and managementEducationImproved problem solvingThe more you teach someone to fish the more than can feed themselves
Benefits of a KaizenAwarenessUnderstanding of broad issues and objectives of the organization as a wholeBetter understanding of Continuous Improvement and the challenges involved with ChangeConfidenceStronger feelings of self-worthEmpowermentIncreased control over the job and work environment which fosters ownership and commitment to the change process
All employees now feel they have a voice in the process!

Waste Identification Sheet
Waste Identification Worksheet
Expl: Waste of Mass InspectionRM,WIP, FGExcessive inspection. When (and if) defects found - we must fix and rush-order shipments.
Expl: Waste of ConveyanceForms are transported to various locations causing long cycle times and high costs with maintaining inventories.
Seven Types of Waste
Waste of DefectsReworking and correcting items, such as forms or orders, that should be done right the first time
Waste of OverproductionMaking more than the next process needs (eg - Inventory)
Waste of Transportation (Conveyance)Long distances traveled in the process to include double-handling of goods
Waste of WaitingLack of supplies or poor utilization of time for a person or machine
Waste of InspectionExcessive inspection trying to find defects from a faulty process
Waste of MotionExcessive movements in the process that may cause health defects
Waste of ProcessingUnnecessary production adds no value and may drive costs up

5S Audit Sheet
In order to attain each level, all criteria must be met with a "Yes" response
Level One (E) - Default*
There is no workplace organization. Usually appears disorganized and dirty.
Parts and garbage are on the floor and in storage bins.
Parts are not labeled properly and/or there is mixed stock under one part number.
Shelves are cluttered with all sorts of items; newspapers, lunches, trash, broken or obsolete stock, etc.
Level Two - (D)YESNO
Area is swept and cleaned. No debris in the work area
The area appears to be organizaed but cannot tell what is and is not required in the process
WIP is well organized
There is no excess or obsolete stock in the work area and all items are labeled
Defective items are quarantined and properly identified.
Level Three - (C )YESNO
All level two requirements have been met and maintained for a minimum period of two months.
Aisles, Equipment and materials are well identified
All non-required tools and equipment have been removed from the work area.
All required tools and equipment are identified and assigned a permanent location that is visible at a glance.
Min-Max levels of WIP have been established and are being adhered to.
Level Four - (B)YESNO
All level three requirements have been met and maintained for a minimum period of two months.
All small tools are identified and located for immediate access
Operators / workers maintain 6 S standards with direction and support from supervision.
Level Five - (A)YESNO
All level Four requirements have been met and maintained for a minimum period of two months.
Operators / workers are maintaining 6 S standards with no direction from supervision.
Operators are searching for opportunities to improve 6 S in the area, especially opportunities for prevention.
