CHAPTER 4 : CASE STUDIES OF ALTERNATIVE QUALITY MANAGEMENT 4.1 Introduction Previous chapters focused on the historic and current state of quality management practice and identified the most common quality management models in use in the highway industry. The focus of this chapter is on the ten case studies conducted by the research team and the relevant analyses and observations of those case studies.

Table 4-1 – List of Case Studies P – Pilot case study The primary criterion for case study selection was that the projects under consideration utilize some form of alternative quality management. While the range of possible alternative quality management procedures leads is long, this one requirement greatly limits the number of potential case studies as most projects still utilize the baseline delivery and quality management methods.

Figure 4-1 – Geographic Dispersion of Case Studies After all the criteria were considered, 10 suitable projects were identified and used as case studies. As mentioned above, one of the most important aspects of all the projects was identification of a champion for the research effort.

found in the Assurance QAO, this was not found in the case studies examined. Similarly, while a project using DBB delivery could potentially allow the contractor to assume a quality assurance role as found in an Assurance QAO, the baseline QAO and the one used on the WSDOT project studied was the Deterministic QAO.
