As a client, you will want to know how your employees have experienced the level of outsourced services. It is an important part of the contract management to measure this on the basis of the opinion of the end user, the assignee. DMC assists in the creation of a professional measuring system and the development of the appropriate questionnaire. In order to achieve an objective form of measurement the questioning needs to be clear and suggestive questions should be avoided. The research results will eventually have to make a constructive contribution to the optimization of the service provision. This requires customization, with DMC as a possible partner to take care of the job upon development as well as operational execution.
