Involvement of technical consultants in high technology business markets Available to Purchase

Using data collected from 302 firms spanning a wide range of industry sectors, tests a model designed to explain the decision of whether to use or not to use an outside technical consultant when purchasing a big‐ticket, high technology product in the information technology area. The results indicate that different categories of variables influence the decision to include or not to include an outside technical consultant in the buying center. In order to assess the degree of convergent validity in our findings, a second model was tested using a somewhat different, but nonetheless related dependent measure, namely the extent of the consultants’ involvement across eight buying stages. Overall, the model testing results provide good support for the majority of the hypothesized relationships, especially those related to the buyer’s access to external networks, product class knowledge, and technical/administrative role. A major finding is that 28 percent of firms in our sample engaged an outside consultant to help them make the purchasing decision. Analysis of the consultants’ extent of participation in these purchasing decisions indicates that they had high involvement in seven of the eight buying stages. Though the consultants were found to have least involvement in the final stage of the buying process, i.e. the selection of the preferred supplier, it seems reasonable to expect that they are key influencers in this final stage as they had a significant effect on shaping all the preceding buying stages.
