In H&Z, we found a partner who ensured that the project results and agreements with the supplier partners were realized in contracts and that we did not have to make any compromises in terms of quality, security of supply, flexibility and service or in our cooperation with the suppliers.

In the past, the operational effort involved with suppliers was enormous. Today, the JAGGAER software solution makes supplier relationship management easier for us and offers RATIONAL full transparency. The tool has reduced the operational effort. This allows us to concentrate more on relevant issues such as strategic alignment.

A tremendous achievement: Having someone by your side with such a foresight and experience is invaluable. The Interim Management support by H&Z helped us in setting up the overall project covering non-procurement topics as well and was decisive for the successful and timely awarding of the 3 core aggregates.
