  • Waste: Any non-value-adding step or action.
  • Eight Categories of Waste:
    1. Transportation: Excess movement of components.
    2. Inventory: Overabundance of products/materials.
    3. Motion: Unnecessary movement of people/equipment.
    4. Waiting: Idle time for information/materials.
    5. Over-Production: Producing more than needed.
    6. Over-Processing: Excess work or steps.
    7. Defects: Products failing expectations.

Popular Lean Systems

  • JIT (Just in Time): Reduces production time and supplier response.

  • Kanban: Visual task and workflow management.

Six Sigma Methodology

  • Focus: Process improvement and defect reduction.
  • Two methodologies: DMAIC & DMADV

DMAIC (Used in Lean Six Sigma)

  2. Measure: Assess current process performance.
  3. Analyze: Identify defect causes.
  4. Improve: Eliminate root causes and enhance processes.
  5. Control: Regular adjustments for sustained performance.
