Prof. Fandel: Chapter 18: Project Management
| Question | Answer |
|---|---|
| Project | A temporary and often customized initiative that consists of many smaller tasks and activities that must be coordinated and completed to finish the entire initiative on time and within budget. |
| Project Management | Involves all activities associated with planning, scheduling, and controlling projects. |
| Activities | Discrete tasks that consume resources and time. |
| Immediate Predecessors | Those activities that must be completed immediately before an activity start. Precedence relationships ensure that activities performed in the proper sequence when they are scheduled. |
| Work Breakdown Structure | A hierarchical tree of end items that will be accomplished by the project team during the project. |
| Project Network | Consists of a set of circles or boxes called nodes, which represent activities, and a set of arrows called arcs, which define the precedence relationships between activities. * Called an activity-on-node (AON) network representation. |
| Critical Path | The sequence of activities that takes the longest time and defines the total project completion time. |
| Critical Path Assumptions: | 1 project network defines a correct sequence of work in terms of tech and workflow. 2 Acts. are assumed to be independent w/ clearly defined start and finish dates 3 act. time estimates are accurate and stable. 4 Act. continues uninterrupted |
| Crashing a Project | Refers to reducing the total times to complete the project to meet a revised due date. |
| Crash Time | The shortest possible time the activity can realistically be completed. |
| Crash Cost | The total additional cost associated with completing an activity in its crash time rather than in its normal time. |
| Crash Cost per time = | (Crash Cost - Normal Cost)/(Normal Time - Crash Time) |
