The Consultants

We deliver solutions with a clear focus on results orientation. The success factors are presented in clearly quantified parameters over time and tracked closely during implementation.


Your Team

The LIQFRIC - Lean Consulting Competency Group consists of consultants with decades of experience in their disciplines who network optimally for your company.

We accompany you in the process recording, the actual analysis and derivation of optimization potential, the conception of consistent, key figure-based target processes.

We have a comprehensive portfolio of tools from the area of Lean and Six Sigma (6σ).

In addition to the tools mentioned, we also have a rich repertoire of other tools that we use as appropriate.

The first on-site analysis is carried out with a screening of the area, the factory or the location. This screening is carried out with at least 2 people from our team and is industry-specific.

The results will be shared with you and form the basis for detailed analyzes and potential assessment.
