Outsourced services for protection and prevention at work (SEPPT) SPMT and ARISTA have decided to merge their organizations to become a major player in Belgium. Accordingly, reorganization of front office activities is intrinsically necessary. Firstly, the merger must be seen at all levels on the ground, through harmonization of processes and the organization itself, for the benefit of clients. Secondly, the changes brought about by changes in legislation require a radical change of the approach to the services offered to clients. The challenges of the new merged entity therefore reside both in the service offers developed and how (new) services offered are provided.
