Point, Flow & System Improvement

By Pascal Dennis

Important that we understand the difference.

Leaders at all levels are responsible for leading improvement commensurate with their scope & span of control.

It makes little sense for a front line Team Leader to hunt the Great White Whale of System Kaizen.

Similarly, it's suboptimal for a Senior Vice-President to focus her attention on solely Point Kaizen - when she should be looking for Moby Dick.

(Caveat: she certainly needs to sponsor, motivate & check Point & Flow kaizen in her zone.)

So here are some working definitions of Point, Flow & System improvement.

Point Improvement
  • improvement in a point in the value stream, e.g.
    • Machine changeover,
    • Material handling
    • Quality - (e.g. damaged to packaging, contamination)
    • Ergonomics
    • Standardized work - lack of, wrong content/sequence/timing etc.

Flow Improvement
  • improvement in several points in the value stream - that lead to an overall VS improvement (e.g. in Lead time, throughput, quality, inventory turns)
    • Flow improvement comprises several point improvements
    • A + B + C + D = overall VS improvement, where A, B, C & D might be
      • Machine changeover,
      • Material handling
      • Quality - (e.g. damaged to packaging, contamination)
      • Ergonomics
      • Standardized work - lack of, wrong content/sequence/timing

System Improvement
  • Entails continuing to ask Why until we uncover systemic causes to recurrent problems
    • Usually entails macro systems around Man, Machine, Methods, Materials
    • Can also entail core business processes - e.g. Budgeting, Forecasting, Info systems etc.

Happy fishing,

  1. Hi Pascal,

    Very clear explanation on the difference and relationship between point kaizen and flow kaizen.

    Can you please elaborate more on how to execute the system improvement?

    Thank you.
