Muda, Mura, Muri Workshop

25th Anniversary LERC Conference: Pre-conference Workshop

You are invited to attend the famous John Bicheno “Muda, Mura and Muri” workshop, where you will have the opportunity to explore the elements of Kingman’s equation – that has been called ‘The Equation of Lean’ – namely, arrival variation, process variation, demand types, load, capacity and process time.

Workshop Aim 

The aim of the workshop is to give participants an in-depth understanding of the elements influencing flow, their interaction, why they are sometimes not appreciated and how they form the basis for a lean schedule.

Participants will also gain an in-depth understanding of why Toyota pays particular attention to Muri, Mura, Muda (generally in that order) and an understanding of the relative influence of variables (other than people) that lead to lean success or failure.


The session is be built around the Muda, Muri, Mura dice simulation exercise, which is played over a number of rounds.

  • The elements of Kingman Equation examined:
    • Arrival variation
    • Process variation
    • Load
    • Capacity
  • Managing demand: necessary, consequential, and unnecessary demands
    • 8 Types of demand
    • Demand waste, capacity waste, process waste
  • Variation: arrival and process
    • What variation are YOU causing?
  • Utilization and Variation together: the tradeoffs: time, capacity, variation
  • Kingman’s Equation and:
    • Six Sigma
    • Scheduling
    • Theory of Constraints
    • TPM
    • Implications for Accounting, Sales and Marketing, HR


The workshop is suitable for lean trainers and operations/service delivery managers in services and manufacturing.
