ch. 17 Flashcards
projects
unique, one-time operations designed to accomplish a specific set of objectives in a limited time frame
project champion
person who promotes and supports a project
Work Breakdown Structure
hierarchical listing of what must be done during a project
PERT
program evaluation and review technique, for planning and coordinating large projects
CPM
critical path method, for planning and coordinating large projects
Network (precedence) diagram
diagram of project activities that show sequential relationships by use of arrows and nodes
Activity on arrow (AOA)
network diagram convention in which arrows designate activities
Activity on node (AON)
network diagram convention in which nodes designated activities
activities
project steps that consume resources and/or time
events
starting and finishing of activities, designated by nodes in the AOA convention
path
sequence of activities that leads from the starting node to the finishing node.
critical path
longest path; determines expected project duration
critical activities
activities on the critical path
slack
allowable slippage for a path; the difference between the length of a path and the length of the critical path
Determinilistic
time estimates that are fairly certain
probabilistic
estimates of times that allow for variation
optimistic time
length of time required under optimal conditions
pessimistic time
length of time required under the worst conditions
most likely time
most probable length of time that will be required
beta distribution
used to describe the inherent variability in activity time estimates
independence
assumption that path duration times are independent of each other; requiring that activity times be independent, and that each activity is on only one path
crash
shortening activity durations
virtual project teams
some or all of the team members are geographically separated
