Abstract
Earned Value Management (EVM) has emerged as an effective method to monitor and control project progress and status. The construction industry has been lagging behind others, such as defense and aerospace, in adopting EVM. The current research was undertaken to explore the barriers to EVM implementation in the construction industry, and aimed at investigating the factors affecting EVM adoption and effective utilization in the construction industry. To achieve this goal, the research followed a qualitative approach by gathering information from literature review and initial industry input to design a questionnaire. A total of 354 completed responses from project managers, project engineers, controllers, and schedulers were collected, of which 203 respondents were familiar with (aware of) EVM. Further, out of the 203 respondents who are familiar with EVM, 126 implemented EVM in their projects while the remaining did not. The data acquired were transformed into two dependent variables and several independent variables for statistical analysis. The responses from EVM-familiar industry representatives were used to analyze the factors that influence the first dependent variable (is EVM implemented), and the second dependent variable (how effectively is EVM implemented) coming from these 126 responses were used to perform cross-tabulation and logistic regression analysis. The results showed that the first dependent variable was influenced by management's commitment level, project budget range, availability of resources, extent work breakdown structure (WBS) is aligned with schedule, difficulty of estimating earned value (EV), detail Level of WBS, and Accuracy of planned value (PV). It was also found that the second dependent variable was affected by the extent execution following schedule baseline, accuracy of PV, availability of resources, management commitment level, difficulty of estimating EV, extent WBS is aligned with schedule, and type of contract. The findings of the statistical analyses were discussed and validated via a focus group consisting of a diverse group of experts from the construction industry.

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
