Williams, T J (2020) Relationships between cost estimates, scheduling and project success in the construction sector. PhD thesis, Walden University, USA.
Abstract
Project failure results in adverse productivity and viability of construction organizations. Construction leaders are concerned with project failure because it disrupts construction organizations' ability to be more profitable and sustainable. Grounded in the theory of constraints, the purpose of this quantitative correlational study was to examine the relationship between project cost estimates, project scheduling, and project success. Archival data were collected from 110 construction companies in Liberia. The results of the standard multiple linear regression analysis indicated the full model was statistically significant, F(2,110) = 40. 85, p < . 001, R2 = . 433. The project cost was statistically significant, p <. 001; project scheduling was not significant, p = . 286. A key recommendation is for project managers to exploit relevant project management training and other capacity development efforts to effectively manage project costs and schedules for success. The implication for positive social change includes the potential to utilize saving from cost and schedule overruns for meaningful programs that will lift the poor and vulnerable by restoring their dignity and enhance their standard of living.

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
