Kaizen Event

Combines observation, waste analysis, and experiments into a focused improvement process with an updated standard.

Ein klarer Ausschnitt des Arbeitsflusses wird intensiv betrachtet, sodass Probleme nicht abstrakt bleiben. Kleine Experimente zeigen direkt, welche Änderung Reibung reduziert und welche nur kosmetisch wirkt. Der Gewinn liegt in der kurzen Distanz zwischen Beobachtung, Anpassung und neuem Standard.

Core question

Which measurable process improvement can the frontline team implement, test, and standardise at the gemba within days?

Participants: 4-10
Time: Typically five days plus 30/60-day follow-up; one to two weeks of preparation.

Evidence building, analysis, and effectiveness review form a multi-stage initiative.

Prepare
Event charter
Clarify scope, baseline, target, team, materials, and decision authority before the event.
Gemba
Current state
Observe current work at the place; make steps, waiting, motion, inventory, and problems visible.
Target
Target condition
Examine waste and causes; design target condition, hypotheses, and daily experiments.
Implement
Tested flow
Build changes immediately, test safely in real work, measure, and adjust daily.
Standardise
New standard
Capture best confirmed flow as standard work; train, assign owner, and set follow-up.

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

A good fit when

Bei einem eng umrissenen Prozessabschnitt mit spürbarer Verschwendung bündelt die Methode gemeinsame Veränderungsenergie. Sie eignet sich, wenn schnelle Lernschleifen und sichtbare Anpassungen gefragt sind.

Ideal for

Operational process improvement
Lean initiatives
Narrow lead time problems

Not good for

Broad strategy questions
Remote-only analysis without process access
Problems without room to implement

Fictional example

Fictional values show the actual method fields.

Event charter

Clarify scope, baseline, target, team, materials, and decision authority before the event.

Scope Saturday handoff; p80 18→12 minutes; Ops sponsor; Warehouse, Support, Booking; no safety trade-offs.

Current state

Observe current work at the place; make steps, waiting, motion, inventory, and problems visible.

32 handoffs: seven-minute search, two return walks, 11 units waiting before handoff.

Target condition

Examine waste and causes; design target condition, hypotheses, and daily experiments.

Sort units by slot; one-way flow; target search <2 minutes and WIP max 8.

Tested flow

Build changes immediately, test safely in real work, measure, and adjust daily.

Rack labels and slot cart built; 24 real handoffs: search 1.6 minutes, no wrong unit.

New standard

Capture best confirmed flow as standard work; train, assign owner, and set follow-up.

Slot cart, scan sequence, WIP8 documented; shift training; Lea owns; 30/60-day review.

Deep dive

Purpose

For a tightly scoped process segment with noticeable waste, the method bundles shared energy for change. It suits situations that call for fast learning loops and visible adjustments.

How it works

A clear slice of the workflow is examined intensively so problems do not stay abstract. Small experiments show directly which change reduces friction and which is only cosmetic. The gain lies in the short distance between observation, adjustment, and new standard.

In detail

A Kaizen Event bundles analysis, decision, and implementation into a short intensive period. Participants observe the process, measure the current state, find waste, and test improvements directly on site. The key is the transition from workshop insight to real change in the work standard. That creates visible progress instead of just a list of actions.

Facilitation

Prepare scope, data, process access, and decision authority. Keep the team close to the gemba and translate observations into experiments quickly. Make sure new standards, owners, and follow-ups are recorded, otherwise the improvement will fade.

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