Thesis Keith Gale 20137.4 Initial statistical analysis of raw data type A – project outcomesOne critical success factor, namely the ability of a supplier to complete a project as‘right first time’ without defects, is selected for initial statistical analysis. Resultsfrom projects, expressed as a percentage of the total for each group is shown inTables 7.1 and 7.2. ‘Yes’ means the project is completed without defects.Table 7.1: Right first time – discrete projects 2006 to 2008Frequency Percent Valid Percent Cumulative PercentValidYes 37 61.7 61.7 61.7No 23 38.3 38.3 100.0Total 60 100.0 100.0Table 7.2: Right first time – framework projects 2008 to 2010Frequency Percent Valid Percent Cumulative PercentValidYes 94 90.4 90.4 90.4No 10 9.6 9.6 100.0Total 104 100.0 100.0Comparison of outcomes in Tables 7.1 and 7.2 show a considerable differencebetween discrete and framework projects for the critical success factor of ‘right firsttime’. Encouraged by differences shown for this factor, additional key projectoutcomes regarding project timescales were examined.126
