Overview of Lean
Creating more value for customer with fewer resources
Philosophy: To provide perfect value to the customer through a
perfect value creation process that has zero waste
Lean reduces cost, improves quality, and speeds delivery by
eliminating non-value-added activity in a process by identifying and
eliminating waste
Lean is not a tactic or a cost reduction program, but a way of
optimizing end to end processes

Types of Waste
What is waste?
Non-value-add activity
Some types of waste with examples
Anything that could have been avoided
Customer is not willing to pay for it
Defects/rework
The 7 types of waste
Muda (Japanese word for waste)
Uncommon common sense

Lean Journey
Lean journey is on the principle I will believe it when I see it
Lowering the tide and uncovering more reefs that can sink the boat
Three stages of Lean journey
Lean operations
Lean enterprise
Lean network

Lean Management
Toyota Production System (TPS)
Based on Fords original thinking
Rebuilding Japanese economy after World War II (1930)
Kiichiro Toyoda, Taiichi Ohno, and others at Toyota
Series of simple innovations to improve process flow and provide
variety in product offerings
Focus on improving end to end processes rather than optimizing
individual machines
Result: Low cost, high variety, high quality, and very rapid
throughput times to meet customer desires

Lean Management
Just-In-Time (JIT)
Introduced by Ford
Supply-chain/ production/inventory strategy
Demand-pull system
Get the right thing at the right time at the right place
Relies on signals between processes to keep things moving
Requires producers to accurately forecast demand and use
integrated production management tools
Saves warehouse space, inventory cost and prevents obsolete
inventory, resulting in higher ROI
