Question
a)
Activity G14 is scheduled to start on day 13th, as preceding activity C12 ends on day 12.
b) i.
On the start of day 35, activity F8 on the critical path is scheduled to start. F8 cannot start till activity E12 is finished. Since E12 is yet only halfway complete, it will take 6 more days to complete E12, an after that F8 can start. Hence, the whole project is going to get delayed by 6 days.
ii.
Without the knowledge of CCPM, project manager can use the PERT and CPM knowledge to assess the project schedule, and if the project schedule is falling behind (as in this case), they can crash activities on the critical path if the project budget allows them.
c)
Activity E6 is scheduled to start on 7th day as per the CCPM schedule.
d) i.
The project's due date is not in jeopardy, as we have a feeding buffer of 8 days to absorb those delays before H10.
ii.
Since, the project schedule is not in jeopardy, I just need to keep a close eye on delays and let buffers absorb the delays.

Explanation / Answer
3. CPM Gantt Chart Layout (Schedule) each graph square = 2 days; CPM Critical Path is A14-D20-F8-H20It is common for activities in projects to run late. What should be DONE when this happens differs between traditional Critical Path Method (CPM) and TOC’s Critical Chain Project Management (CCPM). The upper-most of the two diagrams that follow is a typical CPM Gantt Chart schedule/layout. The lower of the two diagrams is a typical CCPM schedule (with resource, feeding and project buffers included 3.

a) What is the scheduled START date for CPM activity G14? [2 pts.]
b) With the traditional CPM schedule: the project has been underway for 34 days (i.e. it is the start of Day 35). As the project manager, you know that activity B12 was delayed in starting to Day 10 and that it actually took 2 days longer than originally planned. Now, the Yellow resource working Activity E12 tells you that she is only halfway through with that activity! i. What specific information does this tell you about your project (explain why you’re making this claim)? [2 pts.]
ii. What, if you know NOTHING about CCPM and given that you’ve been exposed to MAN 3506 content re: Project Management (traditional PERT and CPM), do project managers in your shoes have to now do? [2 pts.]
c) With TOC’s CCPM schedule, what is the scheduled start date for activity E6? [2 pts.]
d) With the TOC-based CCPM schedule: the project has been underway for 20 days (it is the start of Day 21). You know that Activities B6 and E6 each took 2 days longer than planned. i. Is your project’s due date in jeopardy? Explain how you would know or not. [2 pt.]
ii. What, given that you’ve been exposed to CCPM, do you have to do? Explain your answer. [2 pts.] CPM Gantt Chart Layout (Schedule) each graph square 2 days; CPM Critical Path is A14-D20-F8-H20 A 14 H 20 C12 CCPM Gantt Chart Layout (Schedule) each graph square 2 days, all buffers inserted.
