Mapping Lean Construction adoption by country
Every country. One shared method. Comparable data.
A collaborative benchmarking project where each national Lean Construction institute measures adoption in its country using the same standard method — the German model, adapted locally, compared globally.

About
Why a shared measure matters
LC-MPBI is a decentralised yet standardised programme. Every national Lean Construction institute can run its own market-penetration study using a common framework based on the rigorous German model — generating comparable data on visibility, adoption, maturity, and impact while keeping full national ownership.
Germany 2025 is the first published national picture and the reference design other countries adapt.

How to participate
One Country Lead. One national picture. Six steps.
Step 1
Register as Country Lead
Nominate yourself or a team. The coordinator reviews suitability, capacity, and commitment.
Step 2
Download the complete toolkit
German-model instrument: maturity stages, 4L4D frame, survey design used in 2025.
Step 3
Run the survey in your country
Start when ready. Timing is voluntary — ownership stays national.
Step 4
Submit results
Use the shared template so headline figures sit on the same dashboard.
Step 5
See your country on the live dashboard
Visibility, adoption, maturity, and impact — beside every other country.
Step 6
Publish at a Lean Construction conference
Take the national picture to IGLC or a national congress.
A Country Lead can be an individual or team from a national LCI, university, research institute, government body, or committed practitioners. Multiple leads per country are welcome.

A shared instrument that countries can adapt
Country Lead Toolkit
The practical package for running a national study with the German model. Read the summary below, then download the working documents when you are ready to start.
What's inside
Method Guide — how to run Phase 1 (industry scan), Phase 2 (interviews), and Phase 3 (nationwide survey), with room for local adaptation.
Survey Template — core questionnaire. Wording may be adapted; the locked metrics stay the same so results remain comparable.
Interview Guide — themes and example questions for practitioner interviews.
Industry Scan Checklist — sources and steps to identify Lean companies in your country.
Results Template — format for submitting headline figures to the LC-MPBI dashboard.
One-pager — maturity stages and the 4L4D frame for quick reference.
Directory update — for an organisation already on the list, or a new organisation that represents one country or several. The coordinator reviews it; emails stay off the public site.
Core metrics (locked across countries)
These stay the same in every national study so numbers can sit on one dashboard:
- Five maturity stages — Informed → Piloting → Selective standard → Majority of projects → Culture & strategy
- Share of projects using Lean — e.g. <10%, 10–25%, 25–50%, >50%, all
- Project phases — planning, execution, or both
- Company profile basics — size, role in the supply chain, years applying Lean
- 4L4D frame — the synthesis model from the German 2025 study (levels and dimensions of application)
National questions may be added. Core metrics are not removed or redefined.
How to run it
- Register as Country Lead and receive access to the full pack.
- Download the Method Guide and Survey Template.
- Run Phase 1 — industry scan — to build the national list of Lean companies.
- Optional: Phase 2 interviews to refine local wording and context.
- Launch Phase 3 survey; keep core metrics intact.
- Submit headline figures with the Results Template; full publications go under Resources.

It works
Higher maturity, stronger effect
At Stage 5 every respondent reports positive outcomes.
Not yet standard
Visible, but a thin slice
451 Lean companies vs 300,000+ firms. 71% still apply Lean in under half of projects.
Two risks
Lean light & Leanwashing
Methods without culture, or Lean as a label, poison the next project.
