Vahabi, Ali (2018) Investigating the impact of project scope definition on design-build project performance: A system dynamics approach. PhD thesis, Queensland University of Technology, Australia.
Abstract
This research evaluated how clearly defining project scope, as the first step of project delivery, impacts the time and cost of design-build (DB) projects. To achieve this, a system dynamics method was adopted to develop a qualitative model. The behaviour analysis of this model revealed that improving the level of project scope clarity can enhance cost and time performance of DB projects, even though determining appropriate clarity level is a challenging task. The obtained model can assist clients by providing a clear view regarding the procedures for project scope definition and identifying how to improve the clarity of the project scope.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
