As claimed by Rozemeijer (2008), customers need to be in control of their operative
processes in order to be perceived as an attractive customer, but in order to do this
relevant input to the relationship needs to be in place. Potential, and desired output of
the relationship with a supplier, is quite easy to see, and define but how this output can
be affected by the operative, and strategic processes, is often tougher for the contractor
to realize. Nonetheless, it might be an even tougher challenge for the contractor to see
the connection to the softer input variables like core values, creativity and commitment
and their effect on the efficiency of the contractor-supplier relationship and the
corresponding output.
