Exemplar A

2
Introduction Proman is a company that specialises in managing building projects. It has been contracted to manage a project to build a new shopping mall in Albany.

3
Task a network diagram showing the tasks in the project the tasks in the critical path of the project the minimum length of time required to complete the project the start and finish time for each task the allocation of tasks to a minimum number of supervisors, given that each supervisor will only supervise one task at a time

4
a recommendation of a week when the manager can visit the site and see at least three different tasks in action a discussion about the impact on the project if Task D takes longer than three weeks to complete a discussion about the impact of any other delays significant enough to extend the projects minimum completion time, including the implications for scheduling of supervisors.

Achieved a network diagram showing the tasks in the project the tasks in the critical path of the project the minimum length of time required to complete the project the start and finish time for each task the allocation of tasks to a minimum number of supervisors, given that each supervisor will only supervise one task at a time

6
Merit Establish the critical path and its length the start and finish time for each task the allocation of tasks to a minimum number of supervisors, given that each supervisor will only supervise one task at a time a recommendation of a week when the manager can visit the site and see at least three different tasks in action a discussion about the impact on the project if Task D takes longer than three weeks to complete

7
Excellence a recommendation of a week when the manager can visit the site and see at least three different tasks in action with reasons a discussion about the impact on the project if Task D takes longer than three weeks to complete possibly with added solutions a discussion about the impact of any other delays significant enough to extend the projects minimum completion time, including the implications for scheduling of supervisors. This would include a discussion on float times with respect to project requirements.

Scheduling- critical path

17
Scheduling- Different combinations are possible Supervisor 1: Critical Path A-E-F-G-I Supervisor 2: B-D-H Supervisor 3: C

18
Any delay in the critical path will delay the whole project as there is no float Supervisor 1: Critical Path A-E-F-G-I Supervisor 2: B-D-H Supervisor 3: C

19
With this scheduling, D has a float of 1 week and hence any delay longer than this will delay the project as D must be finished by week 10 so as not to delay G which is on the critical path. Supervisor 1: Critical Path A-E-F-G-I Supervisor 2: B-D-H Supervisor 3: C

20
If there is likely to be a delay in D, we should reschedule to allow D to have its maximum float time of 2 weeks. See reschedule below. Supervisor 1: Critical Path A-E-F-G-I Supervisor 2: B-C-H Supervisor 3: D

21
This seems to be a better schedule as B, H and C would now have a 2 week float as well as D. Supervisor 1: Critical Path A-E-F-G-I Supervisor 2: B-C-H Supervisor 3: D
