A B с D E F G 2.35 3,4,6 4,6,8 3.4.5 4,6,6 4. 5.9 2.3.6 The table above gives the 3-value estimated task durations in weeks i.e. (optimistic, most likely, pessimistic), of A, B, C, D, E, F, G respectively. B3a Calculate the shortest expected duration Te of this project and the path's standard deviation, OTE. (6 marks) B3b Ignoring the non critical paths of this project which have not been shown, calculate what is the scheduled finishing time ts, if this project were to have 90% probability of being completed? (6 marks) B3c According to Goldratt, even if this project were to adopt TS as its completion time, there is still a much high probability of schedule over-run than planned. Why? (8 mark)
