SAP engineering competence for your project Holistic and safe


SAP engineering expertise for your project. End-to-end and guaranteed.
IGZ – the SAP engineers – provide end-to-end coverage for SAP projects in logistics and production.
As a first step, this comprises strategic SAP/IT consulting for a SAP module deployment analysis, as well as high-level plant and process planning.

In the second step, a detailed planning phase is followed by SAP software implementation and the expert integration of process/plant control systems (of any kind) with the SAP software. Implementation is rounded off by our Service/Support: at IGZ, the core competencies for your SAP project can be found under one roof!

With our engineer's mindset and our experience, IGZ ensures that all of the various parts of the project fit perfectly together.
