- Given the information provided in Table 1:
- Prepare an Activity on the Node (AON) Network Diagram ( I recommend you use MS Project or any drawing tool);
- Prepare a table of the possible activity paths and identify the critical path;
- Assume that adding an additional person to the project allows the project manager to reduce any task under PM control that is 4 or more days long by one day (tasks P, Q, and R are external and cannot be changed). How does this affect the critical path, and what is the duration of the project with the added resource?
Important Note: Be sure to take into consideration any special dependencies indicated in the chart (e.g., start-to-start, finish-to-finish) when calculating durations, slack, critical path, etc. The normal dependency unless otherwise stated is finish-to-start. If there is a delay between two activities, it is shown as a plus or minus offset. For example, a start-to-start + 5 dependency means the dependent task is planned to start 5 days after the start of the predecessor task. Any special dependencies shown only apply to the immediate task listed to the left, not to the other tasks in the list.
