Fig. 1 shows a sequence of tasks that are required to complete a project. Start of Project Task 1 Task 2 Task 3 Task 4 Finish of Project Task 5 Fig. 1 The duration of each task is shown in this table: Task Duration 3 There are three paths through this set of tasks. Use the information given in Fig. 1 and in the table to determine the critical path through the sequence of tasks. Each task can have an extra amount of time allowed over its stated duration before it causes the project to be delayed. This is the ‘float’. Explain how you would calculate the float for each of the tasks in the project.

shows a table of tasks for a building project. The tasks F, G, H, I, J and K, need to be carried out between the stages A, B, C, D and E. The project starts with stage A and ends with stage E. Stages B and C are milestones. Task Time taken to complete task Milestones Task starts at Task ends at F A C G A B H B E I C D J D E K C E Draw an activity network diagram to represent the data in the table shown in . Calculate the critical path through the tasks.

A building project has a number of activities, F, G, H, I, J and K, that need to be carried out between the stages A, B, C, D and E. Fig. 2 shows a Project Evaluation and Review Technique (PERT) chart for the building project. F 4 months G 5 months K 3 months J 3 months H 3 months I 2 months D C E B A Fig. 2 The building project has a series of milestones to help the managers monitor the progress of the project. Identify the first two milestones in this project. Describe the critical path through this project. To create the PERT chart, managers first produced a Gantt chart. On the grid below, draw and label the Gantt chart from which the PERT chart in Fig. 2 would have been derived.
