COSC 475 EXAM 2 QUESTIONS & ANSWERS
Purpose of scheduling - answer -to determine:
- project duration
- critical activities (paths)
- early start schedule
- late start schedule
Bar chart (gantt chart) characteristics - answer -- horizontal bar chart
- illustrate start and finish of activities
- dependency between activities is typically not shown
- easy to show current schedule status or % complete
- length of bar corresponds to activity duration
Bar chart advantages - answer -- easy to present project tasks, their durations, and
anticipated start and finish dates
- no special knowledge needed to determine status of project
- suitable for small/simple projects
- created with scheduling software
Bar chart disadvantages - answer -- don't show relationships
- difficult to update schedule
- hard to determine downstream effects of changes
- unsuitable for long or large projects
Bar chart preparations - answer -1. Identify activities
2. Estimate activity durations
3. Develop activity sequence
4. Construct bar chart
Identifying activities - answer -find activities that encompass all of the required project
work, and will serve as the basis for monitoring & controlling the work during
construction
Estimate activity durations - answer -estimate activity durations based on the available
resources and the specified quantity of work
Develop activity sequence - answer -take into account: physical relationship, safety
relationship, resource relationship, preferential relationship
Create a bar chart schedule - answer -you can create this by utilizing the activity
breakdown, estimated durations, and planned activity sequence
Activity on arrow (aoa) - answer -shows the finish to start relationship only
