Thesis Keith Gale 2013contract value does not make a significant difference in project outcomes or criticalsuccess factors for case study projects. Extension of this conclusion is that data fromall case study projects is reliable and represents a statistically close group.7.19 SummaryA review of outcomes classified as raw data in this thesis indicated that case studydiscrete projects achieved performance levels broadly comparable with industrynorms. Although this review compares data from projects that had dissimilarcharacteristics from the case study ones, the comparison provides confidence of ageneral view. Use of comparable statistics from Agile Construction and BEDC OfficeBuildings included in Table 7.5 indicates that the case study experience ofperformance with discrete projects was not unlike those experienced by other clientorganisations. Outcome with defects (BEDC 46% verses discrete 38%) and finishinglate (Agile 70% verses discrete 88%) is as expected.The raw data contrast between case study discrete and framework project issignificant at headline analysis encouraging further investigation at a detailedstatistical level. A series of explorations regarding relationships is undertaken todetermine if bias is detected with results or if influences are present within thedataset which would not be considered normal. Scatterplot diagrams 7.1 to 7.6confirm purity of data with anticipated industry norms.A series of critical success factors aggregated to a project success index suggested byYeung, et al (2008) has been adopted for use by this research from seven CSF’sidentified in Hong Kong building projects. Five CSF’s calculated from organisationpriorities – although specific to this research - use similar criteria and weightings tothose proposed by Yeung. The five CSF’s and relationship with PSI are defined indetail allowing group statistics to be produced for all projects. A graphicalrepresentation of mean results is shown in Figure 7.7.163
