Salehipour, A; Naeni, L M; Khanbabaei, R and Javaheri, A (2016) Lessons learned from applying the individuals control charts to monitoring autocorrelated project performance data. Journal of Construction Engineering and Management, 142(5): 04015105, ISSN 0733-9364

Abstract

The well-known earned value technique measures and evaluates project performance. It uncovers schedule and cost deviations from the baseline plan. However, it is not established to determine acceptable levels of deviations from the baseline. This study applies the Shewhart individuals control charts to overcome this limitation; the charts monitor trends in the project performance behavior and allow them to be detected before the project deviates much from the baseline plan. The study statistically monitors several well-known earned value indexes of a construction project, where the data are autocorrelated and nonnormally distributed. The investigated case showed that the individuals control charts enhance capability of the earned value technique. The authors concluded that implementing the developed tool together with the traditional tools noticeably improves the project controlling scheme and provides more information on project progress. The study extends a previous study in which only independent data were investigated.

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
