The respondents’ comments have been categorised based on whether they relate to
the input, throughput or output of this process. This paper draws on the model presented
by van Echtelt and Wynstra’s (2001) where some modifications have been done in order
to suit the nature of this study. The input category (enablers), concerns input from the
two parties, which affect the prerequisites for an efficient relationship. It addresses
criteria relating to characteristics that are considered important for facilitating
development of the contractor-supplier relationship to enable it to become more efficient.
The throughput category (activities), addresses the criteria directly related to the specific
relationship and the direct contact between the buyer and supplier. The activities and
processes in this category are linked to either the buyer or the supplier but may also be
linked to the reciprocal interface. The output category (results), relates to the outcome of
the relationship, which are the effects of the relationship from both the buyer’s and
supplier’s perspective, such as mutual incentives and decreased total costs.
