Just-In-Time Is...
 A manufacturing system which produces:
 What the customer wants
 In the quantity the customer wants
 When the customer wants it
 While using the minimum:
 Raw materials
 Equipment
 Labor
 Space

Lean Production System
Key Concepts and Tools
 Pace to Takt time
 One-piece flow
 Pull system
SKB
2-6
Importance of Takt Time
 Synchronizes operations to
customer demand
 Prevents overproduction
 Tool for creating flow
 Determines optimal staffing
Net operating time
Customer requirements
SKB
 Drives capacity analysis &
equipment utilization
 Must be updated periodically
as demand changes

JIT Elements
 Small, inexpensive machines in process order
 One-piece flow production, counterclockwise
 Ergonomically-correct operations
 Standing operations, moving while working
 Pull system discipline
 “Standard operations” defined and implemented

JIT Benefits
 Creates a system which is intolerant
of production abnormalities
 Eliminates waste in production processes
 Reduces lead times

Jidoka
A. Tools or Methods to Reduce Defects
 Detect defects when they occur
 Prevent defects from passing to next operation
 Identify root causes of defects
 Eliminate root causes
 Reduce or eliminate defects

Jidoka
B. Equipment autonomation
Separate operator work from machine work
Before: Operator watches machine run
After: Operator loads and moves
 Auto shut-off
 “Hanedashi” auto unload
 Operator moves to next operation
Question: Do you watch your dishwasher run?
