Lean Enterprise: A Comprehensive Overview
Learn Henry Ford's principal success secret: the ability to
identify waste on sight (and to teach this skill to his entire
workforce).
This day-long overview of lean enterprise is designed
primarily for manufacturing engineers, supervisors, foremen, and shop personnel.
Participants will learn the basic foundation of lean enterprise (recognition and
elimination of all forms of waste in the supply chain) as well as its true
origin: Henry Ford's automobile plants and their supply chain.
Kaizen (continuous improvement) was a basic foundation of
the original Ford business system, along with standardization and best practice
deployment. Ford also described and implemented just-in-time (JIT) and most
other quality and productivity improvement techniques that we now think of as
"Japanese." Lean enterprise's American origin is a key asset in
selling it in American workplaces.

- Why
Lean Enterprise?
- This section
shows how to sell lean enterprise to upper management and to the front-line
manufacturing workers who have to make it happen.
- Proven results in
"the language of money" for upper management.
- Lean enterprise's
role in protecting jobs and creating higher wages for front-line workers.
- "Meet Your
Real Instructor" or, "Who do you think taught Japan how to make
cars?" Taiichi Ohno, the father of the Toyota production system, got his
ideas directly from Henry Ford.
- Manufacturing is
the foundation of national prosperity and military security.
- Lean
Fundamentals
- This section
introduces the concept of friction, waste, or muda. This is the foundation of everything that
happens in a lean enterprise. Friction is easy to overlook and it
often becomes built into the job.
- Basic
definitions: Toyota production system's seven forms of waste
- False economy as
waste
- Value analysis
and the process flowchart: identification of value-adding and non-value-adding
activities
- Transportation as
a non-value-adding activity è spaghetti diagrams and factory layout
- The improvement
cycle: standardization, best practice deployment, and continuous improvement
(kaizen)
- Closed-Loop
Corrective Action è project completion, standardization, and best practice deployment
- Lean
Techniques
- This section
introduces specific techniques for suppressing friction or waste.
- Design for
Manufacture (DFM) and Design for Assembly (DFA)
- Group technology
- 5S-CANDO
- Visual controls
and visual production management
- Small-lot and
single-unit processing è Cycle time reduction
- Single-Minute
Exchange of Die (SMED)
- Error-Proofing
(Poka-Yoke)
- Lean Production Control
- Push versus pull
production control
- Kanban
- Synchronous flow
manufacturing (SFM) and the Theory of Constraints (TOC)
- Role of linear
programming (LP) under TOC: identification of constraints and optimization of
the product mixture.
- Suppress
variation in arrival and processing times to reduce inventory and cycle time in
queue.
- The
matchsticks-and-dice experiment in Goldratt and Cox's The Goal shows why
100% utilization "cannot" be achieved in a balanced factory.
- This course
reconstructs the techniques Henry Ford used to achieve close to 100% utilization in a balanced factory!
- Supply
Chain Management
- Extension of lean
manufacturing to the supply chain è a lean enterprise
- Every supply
chain element must add value
- Suppliers must be
capable of just-in-time delivery
- Supplier
development = teaching suppliers lean techniques
- Freight
management systems (FMS) and third party logistics (3PL) systems
- Lean
and ISO 14000
- Lean
manufacturing is synergistic with the ISO 14000 standard for environmental
management systems (EMSs), as well as with ISO 9000.
- Henry Ford made
enormous profits by avoiding or finding ways to reuse environmental waste.
- Change
Management
- Organizational
psychology/ organizational behavior aspects
- Changing the
company culture: "How we do things around here"
- Benefit of the
kaizen blitz
- The need for
upper management commitment
- Lean does not mean downsizing. Cutting jobs when workers improve productivity
guarantees failure of the transformation. This is a very important
consideration when it is necessary to get a union to buy into lean.
Course fee: $1000.00 (per course; any number of attendees)
Theory of Constraints one-day workshop
This one-day workshop goes beyond the Theory of Constraints by showing how Henry Ford achieved what The Goal suggests is impossible: running a balanced factory at 100 percent capacity.
Ford achieved this by suppressing variation in processing and material
transfer times. Learn more about the Theory of Constraints here.
- The
Theory of Constraints
- The
capacity of any manufacturing process is limited by its capacity-constraining
resource (CCR)
- Time lost at the constraint is lost forever
- Identifying Herbie (the constraint)
- Similarities
to program and project management
- CCRs have no excess
capacity and critical path activities have no slack time
- Elevating a constraint (increasing its capacity)
can move the constraint elsewhere, and crashing an activity (paying a premium
to shorten its completion time) can alter the critical path
- Variation
makes it difficult to achieve 100 percent utilization in a fully-balanced
factory
- The matchsticks-and-dice simulation from
Goldratt's and Cox's The Goal
- Performance
Measurements
- (Deficiencies
of the cost model
- Marginal
costs and revenues
- Material and overtime are the only true variable
costs
- Time lost at the constraint is lost forever.
Rework or scrap in the constraint, or scrap after the constraint, cannot be
made up so Six Sigma-level quality becomes particularly important.
- The
throughput model: performance measurements for TOC
- Throughput
- Inventory
- Operating costs
- Production
Control: synchronous flow manufacturing (SFM). SFM supports lean manufacturing
by reducing cycle times and keeping inventory levels low.
- Just-in-time
(JIT) production control methods
- JIT and UniCo's warehouse. Henry Ford described
JIT very explicitly in 1922. Ford's "clockwork" system and takt time.
- Kanban
- SFM Drum-Buffer-Rope (DBR)
- Using
DBR
- Elevating
the Constraint
- Techniques
(most are synergistic with lean manufacturing and/or quality management
systems)
- Single-unit flow
- Work cells instead of "farm" layouts,
especially regarding heat-treatment
- Total productive maintenance (TPM)
- Single-minute exchange of die (SMED)
- Staggered breaks and meal times
- Innovative process redesign
- (Wasted
constraint capacity is irreplaceable. Quality assurance methods protect the
constraint from nonconforming pieces.
- Go/no-go gages and error-proofing (poka-yoke)
- Design for manufacture (DFM) and Six Sigma
quality
- Linear
programming (LP) to optimize product mixtures and model the effect of
increasing the capacity of a constraint
- The slack
variable shows each operation's excess capacity. It is zero for the CCR(s)
- The shadow
price shows the differential benefit of elevating a constraint
- Variation
Reduction (a unique element of this course)
- Variation
in processing and material transfer times make it impossible to achieve 100
percent utilization in a balanced factory (one in which all the operations have
the same capacity)
- Henry
Ford succeeded in running a balanced factory at close to 100 percent capacity.
- Subdivision of labor
- Use of conveyors or work slides to transfer work
across short distances
- Go/no-go gages and error-proofing (poka-yoke) to
prevent nonconforming work or at least keep it out of critical processes
- Conclusion:
TOC and Your Factory
- Is
your inventory just-in-time or just-in-case?
- How
is your plant's performance measured?
- Identifying
the constraint: per Ford, a pile of work-in-process (WIP) in front of an
operation indicates a problem.
- Does your constraint work at full capacity?
