Flashcards

Lean Culture

A culture focused on continuous improvement, efficiency, and waste reduction through specific methods like PDCA, standardization, visual management, and teamwork.

PDCA Cycle

Plan-Do-Check-Act; a four-step problem-solving methodology used to continuously improve processes, systems, and results.

Standardization

Establishing the best current method for a process or task to eliminate inconsistencies and variability.

Visual Management

A system for making information easily visible to everyone so that everyone can understand the current state of the process and identify areas for improvement.

Study Notes

Lean Culture Objectives

  • What is lean culture?
  • PDCA
  • Standardization
  • Visual management
  • Teamwork
  • Paradox
  • Intensity & do of lean culture
  • How does lean culture feel?

What is Lean Culture?

  • Daily experience of team members
  • Current behavior
  • Includes: Plan-do-check-act, Standardization, Visual management, Teamwork, Paradox, Intensity, the do concept

PDCA

  • Grasping the situation (big picture, key parts, what is-should happen, trends, value-goal-related)
  • Plan (5Ws + 1H, measurement plan, visual system)
  • Do (contains its own PDCA cycle with pilot activities; assessment of team capabilities, assess current condition)
  • Check (metrics to check outcome (final score) and process, go see what is happening)
  • Act (reflect on condition, standardize when outcomes are on-target, make countermeasures when outcomes are substandard, stop bleeding or root cause)
  • Manager's job: practice and teach PDCA daily
  • Warm Heart Principle: Hard on problem, easy on people

Standardization

  • Standard = best current method, continuously changing
  • Standards make out-of-standard conditions obvious
  • Problem = deviation from standard (gap)
  • Problem-solving funnel
  • Five Whys (get at root cause, usually inadequate standards, adherence to standard, or system)

Problem Solving

  • Problem = deviation from standard (difference between what should be happening and what is happening)
  • Problem solving process using a funnel
  • Grasp the situation: actual vs standard, actual vs ideal
  • Breakdown: Big vague concern
  • 5Whys: identify point of why cause time and place events are causing abnormality
  • Root cause: find the cause
  • Countermeasures = solutions

Visual Management

  • Visual management triangle
  • Management as theatre (problems made visible)
  • Line-side process reviews
  • Safety/quality "auctions" (presentations, attendees can ask questions)
  • Current condition presentations
  • Hoshin (strategic) planning presentations

Teamwork

  • Safety first (core value like productivity & quality)
  • Uniforms (same regardless of position)
  • No executive offices, no walls
  • No executive dining rooms or parking
  • Genchi genbutsu (Go see) - shop floor

Paradox

  • Jidoka - Stop production so that production never has to stop.
  • Standards - change all the time
  • One-at-a-time production (more effective than batch)
  • Maximizing unit efficiencies (does not always maximize overall efficiency)
  • Don't make something unless customer orders it
  • Team members (not industrial engineers develop standardized work)
  • Seek perfection (even though we know we will never achieve it) (humility)

Intensity & "Do" of Lean Culture

  • Intensity: more and greater demands (recognize muda (waste), kaizen (small improvements))
  • Recognize strain
  • Provide support & training
  • Maintain intensity of improvement
  • "Do" concept: path or way to follow
  • Humility, Lifelong learning, Respect for people

How Does Lean Culture Feel?

  • Disciplined
  • Freewheeling
  • Warm
  • Indomitable (PDCA gives scientific discipline & freewheeling spirit, builds respect, creates warmth, no "them vs us")
