Operations Analysis method

Waste Analysis

Identifies waste along a process, prioritises impact, and derives improvements.

The flow is read along its value creation so wasteful activities can be distinguished from the actual contribution. Friction and detours become structural signals rather than individual blame. The analysis provides a basis for reducing effort while protecting quality.

Core question
Which work creates customer value, which waste is immediately avoidable, which is currently necessary, and which unevenness or overburden produces it?
Participants
2-8
Time
60–120 minutes for a bounded value stream; add gemba observation.

The steps form one complete method run.

  1. Value

    Value criterion

    Define customer, outcome, and conditions under which an activity creates value.

  2. Observe

    Observed flow

    Capture steps, times, paths, inventory, interruptions, and strain in actual flow.

  3. Classify

    Waste register

    Classify non-value work as Muda type 1 or 2, unevenness as Mura, and overburden as Muri.

  4. Prioritise

    Priority

    Assess risk, frequency, time, and relationships; choose system cause rather than visible symptom.

  5. Test

    Improvement test

    Run a small countermeasure with prediction, owner, guardrails, and review.

Add new evidence at review and version decisions with the prior state.

A good fit when

Bei einem Prozess, der viel beschäftigt, aber wenig Wert schafft, legt die Methode Verschwendung offen. Sie richtet den Blick auf unnötige Wege, Wartezeiten, Nacharbeit und Übererfüllung.

Ideal for

  • Lean process improvement
  • Lead time reduction
  • Operational efficiency

Not good for

  • Problems without process visibility
  • Pure creative work
  • Unclear customer value definition

Outputs

  • Improvement test

    Waste register with value relation, Muda type 1/2, Mura, Muri, evidence, cause, and prioritised experiment.

First step

Set one concrete value stream, customer, and desired outcome; observe actual work at gemba.

Deep dive

Purpose

For a process that keeps people busy but creates little value, the method exposes waste. It directs attention to unnecessary movement, waiting times, rework, and overdelivery.

How it works

The workflow is read along its value creation, so useless activities are clearly separated from the actual contribution. This makes friction and detours appear as a structural problem rather than individual failure. The analysis provides the basis for noticeably reducing effort without losing quality.

In detail

Waste Analysis uses the Lean idea that not every activity creates value for the customer. The method looks at process steps through categories such as transport, inventory, motion, waiting, overproduction, overprocessing, defects, and unused talent. That makes costs, delays, and quality problems tangible. The patterns lead to concrete improvement ideas for flow and quality.

Facilitation

Work close to the real process and use observable examples instead of abstract accusations. Treat the waste categories as a search aid, not as dogma. Finish by prioritizing a few improvements with high impact and a clear owner.

The method guide walks execution through 5 phases, timing, 5 pitfalls, and clear stop criteria.
