Quality – Our basis for continuity

“PROBIOTEC is a service company that constantly faces competition. We can only be successful in the long term if we succeed in building the trust of our customers with every service we provide.”

This principle of our quality policy has been embedded in our company since we established the first quality management system in 1995. In accordance with our guideline that quality is the basis for continuity, our aim is to continuously develop our quality management system so that we can meet the constantly changing demands of the market and our clients on this basis.

The weyer group claim of “allround. smart” fits well here: The word “allround” in the claim indicates that the weyer group is capable of providing every service and expert report need in and around industrial plants from one single source. “Smart” refers to the fundamental offering, which encompasses knowledge-based services and products. Our “smart” solution for the customer’s problem represents our unique selling point.

By incorporating our subsidiary BDO Technik- und Umweltconsulting into the quality management system at PROBIOTEC, we ensure that we can direct and monitor all areas of our daily work with a single goal: to provide the best quality of service to the complete satisfaction of our clients.

Every job at PROBIOTEC depends directly or indirectly on the quality of our work. This is our unique selling point along with our bespoke order processing for our customers. Everyone in the company is responsible for the quality of their work. Our goal is to meet the client’s requirements as well as we possibly can and continuously develop and improve ourselves. Our management team and workforce work together to create a climate that ensures open communication in mutual respect for one another and creativity and innovation.
