(a) Draw the project network. Use activity on node (A-O-N) method. (b) Calculate the length and variance of the Critical Path. (c) Identify the non-critical activities! Work out the Total Slack (TS) and Free Slack(FS) for all the non-critical activities. (d) State whether the network is sensitive or insensitive! (a) Draw the project network.
