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.
This research has provided guidance through the following accomplishments: â¢ Documentation of practices as found in quality management literature, surveys and case studies; â¢ Analysis of the benefits and challenges of the alternative QMS through rigorous and scientific case study means; â¢ Identification and definition of five fundamental QAOs for highway design and construction projects; â¢ Identification and definition of ten factors influencing the selection of a QAO for highway design and construction projects; â¢ Development of a selection model for matching these systems to alternative project delivery methods; â¢ Increasing industry understanding of the impacts that alternative QAOs have on highway design and construction projects; and â¢ Providing agencies with a roadmap of changes to the baseline QMS to accommodate alternative delivery methods.
The research defines the roles and responsibilities of all project stakeholders (agency, contractor, designer and consultants) in a clear and understandable manner.
The research also describes each of the fundamental QAOs through a description of the stakeholderâs roles and responsibilities, and the applicable project delivery methods.
Collateral Assignment Of Beneficial Interest - Scope And Limitations Of The Study In Thesis
The results provide a better understanding of the impact that a particular QAO has on a project.
Continued advancement will take a willingness of STAs to implement alternative QMSs and measure their effectiveness.
It has taken decades to establish the baseline QMS.
These champions will need to educate their peers and serve as resources for implementation.
6.3 Limitations of the Research Due to the nature of the research questions and the limited use of alternative QMSs in the United States, this research was based on largely qualitative research methods.
