Thesis Keith Gale 2013Figure 7.1 illustrates the relationship between tender total and variance of projectduration. It was anticipated that no such relationship would exist, and the scatterplotconfirms this. Projects generally group around the zero value on the X axis –indicating that most projects are completed ‘at around’ the due date. This groupingacts along a vertical plane with a balanced variation of timescales irrespective offinancial size of project value. The assumption that timescale variance does notcorrelate with project financial value is confirmed by placement of results for bothdiscrete and framework projects.Figure 7.2: Scatterplot graph exploring relationship between agreed initialduration and actual duration for project timescalesConclusions from Figure 7.2:Figure 7.2 illustrates relationships between the agreed initial duration and actualproject duration. It was anticipated that a relationship would exist, and a strong linearresult shown by scatterplot confirms this. As most projects follow a 45 degree axis,there is strong correlation between initial and actual project timescales. Actualduration is invariably in excess of agreed duration and therefore variation is to the132
