Abstract:
One of the factors that affect project quality and customer satisfaction is a service of consulting engineering teams. However, consulting engineering teams in the same company may present a different level of service due to experience and practice of each consulting engineering team. This reflects unreliability of consulting engineering firm. Hence, the improvement and control of service level is necessary. Previous researches about consultant service evaluation were found disadvantage. For example, factors for evaluation were developed in other countries and these factors may be concerned differently from Thai consulting practice. In addition, the assessment of service level always uses personal judgment of assessor so this causes the uncertainty of assessment result. Therefore, this research aims to determine factors and develop criteria for evaluating service level of consulting engineering teams. From literature review and in-depth interviews with 10 experts we can summarize factor for evaluating 34 factors and group factors into construction stages and general service. Results of analysis based on Likert scale found that the most important factor for service evaluation is an experience of project manager, completeness and accuracy of document for hand-over a project and approval shop drawing respectively. The development of criteria for evaluating each factor begins with in-depth interviews with 13 experts and a brain storming. During reviewing criteria, we can separate them into two characteristic, which are qualitative and quantitative criteria. In this research Delphi technique is used to confirm qualitative criteria and indicator of quantitative criteria. On the other hand, quantitative criteria are developed by Fuzzy logic. From the integration of criteria, factor and weighting factor, we can develop a model for evaluating service level of consulting engineering teams. The benefit of this research is to help consulting teams know a current level of their service and they can use this information to improve their service.
