QUESTION 2: (20 marks) 2. Critical Path Method (CPM) is a network diagramming technique used to predict total project duration and to determine the critical path. a) Based on the table provided, create the CPM network diagram. Analyse and show the Early Start (ES), Early Finish (EF), Late Start (LS), Late Finish (LF) and the Float/Slack duration (14 marks) b) Analyse the diagram, state and circle the Critical Path clearly.
