Result
€ 2.375.046 besparing (20%) · ROI 3,6:1
Prefaco Houthalen and Lommel are part of the international organisation CRH. CRH is a listed company where around 70,000 employees in 35 countries work together towards a turnover of more than €17 billion. Within the Products Belgium division, Prefaco Houthalen and Lommel are two production sites. We felt that efficiency could be better in both production plants as well as in both drawing offices. We chose Vocum as an external partner to achieve these goals. At the start of the collaboration with Vocum, 280 FTEs were active in production, maintenance and the drawing offices.
During an analysis, Vocum established that a potential saving of €2,375,046 was possible within the scope above. This corresponds to a productivity improvement of more than 20%.

Led by Christophe Holthof, the project team achieved a strong result thanks to a number of structural changes. We have summarised the most important ones below:
- There was insufficient focus on efficiency in production and in the drawing offices. By defining the right KPIs and steering on them, this focus — and efficiency — increased by 20%.
- A complete management system was developed, so that problems and deviations from the target are noticed in good time. This means action can be taken at the right moment and at the right level.
- A production schedule was created, enabling the plant managers to determine several days in advance how many people are needed for the planned work. With this information they are also better able to motivate and challenge their department heads.
- Intensive training was provided, both in the classroom and on the job, with the aim of better enabling supervisors to manage a group of people on the basis of facts and figures. The supervisors here are the plant managers, department heads and foremen.
- The two drawing offices in Houthalen and Lommel were centralised into a single department in Houthalen. This allowed the work to be planned better and the people to be managed better. Drawing errors are also better managed and productivity rose by 15%.
- By placing more focus on overtime, it was reduced by 30%.
- Daily planning was implemented in the maintenance department to enable better transparency and follow-up of maintenance tasks.
- The training needs were mapped out. On this basis, a training plan was developed that increased the flexibility of the employees. Replacements were also appointed and trained for the supervisors.
- Communication between the various departments and levels improved through the use of the new management system.
The points above, together with continuous guidance from the Vocum team, enabled us to achieve the target of €2,375,046 — a 20% productivity increase — on an annual basis. This corresponds to an ROI of 3.6:1.
We are very pleased with the way Vocum brought the project to a successful conclusion and recommend Vocum to any company that has a change process with measurable results in mind. Partly because of this result, we have decided to have a new analysis carried out together with Vocum at two other production sites.
