Produce a network showing the activity mean durations, mean earliest start

and latest finish for each activity, the critical path and the estimated overall

mean duration for the work package.

(10 marks)

Calculate the probability of the work package being completed within 30

weeks.

Differentiate between logic-driven and resource-driven work logic flow

scheduling and discuss the approach most likely to be adopted by PME in

planning the work elements. Support your answer with appropriate examples

in the context of the case study.
