Lean Six Sigma boosts Parmaco’s productivity and continuous improvement

As experts in dynamic architecture, we constantly seek new ways to serve our customers more flexibly and efficiently. Our rental buildings adapt to changing needs. They can be expanded or reduced, relocated, and repurposed. To keep pace with customer expectations and industry demands, we continuously refine our processes just as systematically as we develop our buildings.

As part of our continuous development, we launched our Lean Six Sigma program in October 2025. The program aims to strengthen the competence of our personnel and to significantly accelerate the improvement of company-level productivity.  

What is Lean Six Sigma? It is a methodology that brings together Lean thinking and Six Sigma. Lean focuses on eliminating waste, while Six Sigma reduces errors and variation. The aim is to enhance both the efficiency and quality of processes. The first results of the program show that systematic continuous improvement produces tangible value already in the short term.

Kalle Josefsson, Director, Operational Excellence & Finland Delivery Operations, is responsible for the program as a whole and its implementation as part of Parmaco’s everyday life.

We asked Kalle about the Lean Six Sigma program.

Q: What is the goal of the Lean Six Sigma program at Parmaco?

A: The goal is to increase our personnel’s understanding of the Lean Six Sigma method and to accelerate the improvement of company-level productivity significantly. We want to promote a systematic, data-driven way of developing our operations and ensure that improvements are measurable and permanent.

Q: What is the current stage of the program?

A: The program was launched in October 2025. The first training rounds have already been carried out in Finland and in Sweden.

During the year, we train four groups, i.e., one per quarter. The goal is that by the end of 2026, we will have about 60 Lean Six Sigma Yellow Belt – i.e., people trained at the basic level from different parts of the organization.

Q: How is the training reflected in practice?

A: The training always includes a practical project. Through projects, we typically seek improvements of 25–50% in selected development areas. These may include, for example, issues related to assembly or improving the efficiency of module handling.

Q: Has the program already produced results?

A: Yes. The projects in the first round of training will repay the costs of the program for the realization of 2025 and the plan for 2026.

In the future, our goal is for our Lean Six Sigma investment to yield at least 5–10 times the benefit of the investment.

Q: What is the long-term goal for the program?

A: In the long term, we aim for a situation where at least half of our office employees are trained at the Lean Six Sigma Yellow Belt level and about 10% at the next, Green Belt level.

This ensures that systematic continuous improvement is not a separate project, but an integral part of Parmaco’s daily operations and corporate culture.

The Lean Six Sigma program is a key step towards a more efficient, high-quality, and competitive Parmaco – together and continuously evolving.
