It will take highly motivated individuals and champions of change before the industry can truly realize the impacts of these advances.
The challenges of implementing alternative QMS processes are similar any process changes in large public or private organizations.
The survey conducted in this research did not, for the most part, yield statistically significant results.
Rather, the survey led the team to a sample of diverse case studies from which to draw conclusions.
It is possible that additional QAOs not identified in this research may develop in the future as the industry becomes more comfortable with alternative project delivery methods and more comfortable with the contractor taking on more responsibility for quality.
The development of additional fundamental QAOs implies that the industry is embracing not only alternative project delivery, project management and quality methods, but also developing relationships with contractors that are built up trust, the contractorâs expertise, and a willingness to shift more quality responsibility to the contractor.State highway agencies must consider several challenges when deploying this research.Challenging the status quo and creating a cultural change requires leadership and mentoring to ensure that alternative QMSs are thoughtfully applied.CHAPTER 6: CONCLUSIONS, LIMITATIONS and FUTURE RESEARCH 6.1 Conclusions Quality management systems in the United States transportation industry are evolving.Innovations in QAOs and other features of quality programs are being used by STAs across the country on projects with both traditional DBB delivery and alternative delivery methods.The development of measures to assess the performance of QAOs is a topic for future research.The complexity of the topic was evident by a variety of conditions within the industry. For example, there is widespread inconsistent use 138 of quality terminology throughout the industry.However, these alternative quality management systems are being applied on a project-by- project basis due to the lack of national guidance to promote standard approaches.For highway agencies, this lack of guidance is resulting in significant investment to develop individual programs and minimizing the ability to capture and utilize knowledge across agencies.Quality management research should strive to lead this change. â¢ What levels of quality performance result from each QAO variation?â¢ What additional tools are available to assist with incremental changes to the baseline systems?
