Three types of Waste

Muda : Non-value added work Muri : Overburden Mura : Unevenness

Page 13

Muda the 7 Deadly Wastes

1.Overproduction 2.Transportation 3.Waiting 4.Processing methods 5.Inventory 6.Motion 7.Defects
Page 14


Waste exists in every formand in all areas of a manufacturing process. Lean Manufacturing Tools and Techniques aid in the rapid identification of waste elements and provides permanent solutions to improve the process.
When a business develops into a Lean Enterprise, the team will take a zealous approach to eliminating wasteful activities.

Takt time

Available Working Time
Customer Demand • The rate ofproduction required to meet the customer’s demand rate.

Phase 1 & 2  Phase 1: Evaluation
• Opportunity
– – – – – Products and flow Processes Equipment Workplace Organization Demand Level

Phase 2: Planning
• • • • • Charter development Objectives and boundaries Data collection and documentation Workshop logistics Team memberselection

• Readiness
– Need for rapid improvement – Enthusiasm/spirit – Culture

Phase 3: Workshop “Week”
• • Thursday before workshop – Management briefing (1-2 hours) Friday before workshop – Lean Education day, including Standard Ops Tools – Process walk – Introduce teams, review charter Monday – Quickly review Charter – Process Sponsor verbalizes commitment to team – Takeaction - document/simulate/implement Tuesday through Thursday – Document/simulate/implement Friday – Final report out – Celebrate the team‟s success
