It is a well-established fact that construction is a complex process that involves technical and personal skills and requires many entities to work together to achieve a successful result. For that reason, formal partnering on construction projects in recent years throughout the United States has become a popular approach to total quality management. Although most owners and contractors agree that partnering is a benefit to project performance, sometimes project participants go through the motions without really committing to the process. The Arizona Department of Transportation has developed a sophisticated partnering evaluation system that can measure the performance of its project teams relative to their ability to work together. The result is an accurate assessment tool that can be used by all members of the project team to determine at any time during the project if a performance problem is brewing and that thereby allows the team leadership to react and take corrective action.
