Supermarket Management: Lean Six Sigma Methodology

Key Issues

  1. Handling various kinds of waste at the supermarket.
  2. Addressing supply chain issues causing delays in the morning delivery of milk.

Solution: Incorporate Lean and Six Sigma methodologies, combined as Lean Six Sigma.

Lean Methodology

  • Focus: Providing value to the customer, eliminating waste, continuous improvement, reducing cycle time.
  • Waste: Any step/action in the process that a user does not gain any value from.

Types of Waste (8 categories)

  1. Transportation: Excess movement of people, tools, inventory, equipment beyond what is required.
  2. Inventory: More products/materials than required leading to damage, inefficiency, etc.
  3. Motion: Time/effort wasted due to unnecessary movement of people/equipment.
  4. Waiting: Time wasted waiting for information, instructions, materials, equipment.
  5. Over-Production: Producing more products than required.
  6. Over-Processing: More work/components/steps in a product/service than required.
  7. Defects: Products/services that fail to meet customer expectations.
  8. Skills: Under-utilizing human potential, delegating tasks to inadequately trained people.

Lean Methods

  • JIT (Just In Time): Reduces production system time and supplier response time.
  • 5S: Focuses on cleanliness and organization, improving efficiency and profits.
  • Kanban: Visual method to manage tasks/workflows; helps identify and fix process issues.

Six Sigma Methodology

  • Focus: Process improvement and defect removal.
  • Major Methodologies: DMAIC and DMADV.

DMAIC Methodology (Lean Six Sigma uses DMAIC)

  1. Define: Determine project goals (e.g., timely milk delivery pre-8:30 AM).
  2. Measure: Measure current process performance (e.g., milk truck routes and times).
  3. Analyze: Identify defects and their causes (e.g., adjusting start times and routes).
  4. Improve: Address and eliminate root causes (e.g., change route, advance milk pickup to 6:30 AM).
  5. Control: Regular adjustments and continuous monitoring to improve future performance.

Benefits of Lean Six Sigma

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