Lecture Notes: Lean Six Sigma for Supermarket Management

Introduction

• Two main issues at the supermarket:
  1. Handling different kinds of waste
  2. Addressing supply chain issues causing delayed milk delivery
• Solution: Incorporate Lean and Six Sigma methodologies
  • Lean: Known for handling waste
  • Six Sigma: Known for process improvement
  • Lean Six Sigma: Combines concepts of both methodologies

Lean Methodology

• Focuses on providing value to the customer by:
  • Eliminating waste
  • Continuous improvement
  • Reducing cycle time
• Definition of waste: Steps or actions without customer value
  • Example: Unnecessary truck movement for milk delivery
• Eight Categories of Waste:
  1. Transportation: Excess movement of people, tools, etc.
  2. Inventory: Overproduction leading to damage, inefficiency
  3. Motion: Unnecessary movement wasting time/effort
  4. Waiting: Time wasted waiting for information or equipment
  5. Over-Production: Creating more products than needed
  6. Over-Processing: Extra steps or work beyond necessity
  7. Defects: Products/services not meeting customer expectations
  8. Skills: Underutilizing human potential

Lean Techniques

• Just In Time (JIT): Reduces production time and improves supplier-customer response time
• 5S Methodology: Focuses on cleanliness, organization, efficiency
• Kanban: Visual task and workflow management to identify and fix issues

Six Sigma Methodology

• Set of tools/techniques for process improvement and defect removal
• Two Major Methodologies:
  1. DMAIC: Used in Lean Six Sigma
  2. DMADV: Learn more from a Six Sigma video

DMAIC Methodology

1. Define: Determine project goals (e.g., reduce milk delivery time)
2. Measure: Evaluate current process performance (e.g., route timing)
3. Analyze: Identify reasons for defects (e.g., route traffic issues)
4. Improve: Implement changes to eliminate root causes (e.g., change pickup time and route)
5. Control: Regularly adjust and monitor processes for continuous improvement

Benefits of Lean Six Sigma

1. Increased profits
2. Standardized and simplified processes
3. Reduced errors
4. Employee development
5. Added value to customers
