PART1 :

Given the following activity assumptions table:

Immediate Duration

Activity Predec. (Days) Name

A -- 6 Pre-project

B -- 2 Market study

C A 3 Feasibility study

D A 5 Realization

E A 3 Definition of marketing policy

F C 2 Cost estimation

G D 3 Prototypes presentation to the customer

H B,E 4 Determination of the cost of the product

I H 2 Evaluation of the turnover

J F,G,I 2 Synthesis report before the start of the series

1. Draw the CPM network adding the following information: Activity time, Duration, Early Start Time (ES), Early Finish time (EF), Late Start time (LS), Late Finish time (LF), Slack (4pt)
2. Analyze the paths through the network and find the critical path (1pt)
3. Calculate the total slack time in the network (2pts)

4. Explain briefly, What would you do different if you were asked to use PERT method instead of CPM method? (3pts)
