Question 1
1.1 Ben is planning to get married at the end of the year. He just attended a Project Management
course and attempts to utilize the tools and techniques that he has learnt on the course for planning
his weeding. A work breakdown structure was constructed and the details are given in the
following. Based on the information given create a network for this project.
Note: Do not include summary tasks in the network (i.e., 1.3, Ceremony, is a summary task; 1.2,
Marriage license, is not a summary task). Do not consider who would be doing the task when
constructing the network. For example, do not arrange “hiring a band” to occur after “florist”
because the same person is responsible for doing both tasks. Focus only on technical dependencies
between tasks.
Hint: Start with the last activity (wedding reception), and work your way back to the start of the
project. Build the logical sequence of tasks by asking the following question: In order to have or
do this, what must be accomplished immediately before this? Once completed, check forward in
time by asking this question: Is this task(s) the only thing that is needed immediately before the
start of the next task?

2.2 Ali signed a contract to build a stable for UTM. Amongst the clauses in the contract include a RM
500 bonus for completing the project within 15 days and a penalty of RM 100 for each day the
project takes longer than 15 working days. The project network for building the stable and the
duration for the activities are given in Figure 2.1. Calculate the activity times and the slack for all
the activities. Also determine the critical activities, critical path and the project duration. Will Ali
get a bonus or a penalty for this project?

Question 4
The network (Figure 4.1) and details of a project are given in the following. Consider shortening the
project duration by crashing the activity duration. Ensure that there is minimum increase in the direct
cost. Compute the total direct cost for each project duration. If the indirect costs for each project
duration are $400 (19 time units), $350 (18), $300 (17), and $250 (16), compute the total project cost
for each duration. Plot the total direct, indirect, and project costs for each of these durations on a costtime graph. What is the optimum cost-time schedule for the project? What is this cost?
