The 8 Wastes - TIMWOODS

Transportation

Unnecessary movement of materials, products, or information

Examples:

  • Moving parts between distant workstations
  • Multiple handling of materials
  • Excessive email forwarding

Inventory

Excess materials, products, or information not being processed

Examples:

  • Overstock of raw materials
  • Work-in-process buildup
  • Unused information systems

Motion

Unnecessary movement of people during work

Examples:

  • Searching for tools
  • Excessive walking
  • Repetitive reaching or bending

Waiting

Idle time when people or machines are not productive

Examples:

  • Machine breakdowns
  • Waiting for approvals
  • Queue times

Over-production

Producing more than what is needed

Examples:

  • Making products ahead of demand
  • Running large batches
  • Generating excessive reports

Over-processing

Adding more value than required by customer

Examples:

  • Excessive features
  • Multiple quality checks
  • Gold plating solutions

Defects

Products or services that don't meet quality standards

Examples:

  • Scrap and rework
  • Service errors
  • Incorrect information

Skills

Underutilizing people's capabilities and knowledge

Examples:

  • Not listening to suggestions

  • Designate specific locations
  • Label everything
  • Create visual controls

Shine (Seiso)

Clean and maintain workplace

  • Deep clean workspace
  • Identify sources of dirt
  • Make cleaning routine

Standardize (Seiketsu)

Create standards and procedures

  • Document best practices
  • Create checklists
  • Establish routines

Sustain (Shitsuke)

Maintain discipline and continuous improvement

  • Regular audits
  • Training programs

Value Stream Mapping (VSM)

Definition

A visual tool to analyze current state and design future state of material and information flow

Steps

  1. Select product family
  2. Draw current state map
  3. Analyze current state
  4. Design future state map
  5. Create implementation plan

Key Metrics

  • Cycle Time
  • Lead Time
  • Value-Added Time
  • Value-Added Ratio
  • Process Efficiency

Kaizen - Continuous Improvement

Philosophy

Small, continuous improvements involving all employees

P

Plan

Identify problem and plan solution

D

Do

Implement solution on small scale

C

Check

Measure and analyze results

A

Act

Standardize and deploy if successful

SMED - Single Minute Exchange of Die

Methodology

Reduce setup and changeover times to under 10 minutes

1

Separate Internal and External

Distinguish between activities requiring machine stop vs. running

2

Convert Internal to External

Move as many internal activities as possible to external

3

Streamline All Activities

Improve efficiency of both internal and external activities

Case Study Results

  • Before: 45 minutes average setup time
  • After: 8 minutes average setup time
  • Improvement: 82% reduction
  • Annual savings: $120,000

Poka-Yoke (Error Proofing)

Techniques

Prevent or detect errors before they cause defects

Prevention Methods

Make errors impossible to occur

  • Different sized connectors
  • Color coding
  • Shape coding

Detection Methods

Identify errors when they occur

  • Sensors
  • Checklists
  • Automatic shutoffs

Real-World Examples

  • USB connectors only fit one way
  • Car won't start unless in park/neutral
  • Microwave won't run with door open
  • ATM retains card until cash is taken

Just-In-Time (JIT) Production

Concept

Producing the right items at the right time in the right quantities

Pull System

Production triggered by customer demand

  • Reduced inventory
  • Lower costs
  • Better quality
  • Flexibility

Kanban System

Visual signals that trigger production

  • Production kanban
  • Withdrawal kanban
  • Signal kanban

Takt Time

Rate of customer demand

Formula:
Available work time ÷ Customer demand

Example:
480 minutes ÷ 240 units = 2 minutes per unit
