Flashcards in chapter 6 exam Deck (63)
tool used for planning, scheduling, and monitoring project progress
what are four things the project network depicts?
project activities, logical sequences, interdependencies of activities, and times for activities to start/finish
what is a framework for project information system used by project managers to make decisions concerning time, cost, and performance?
what are project networks developed from?
element in project that consumes time
what is used to build the activities found in the project network?
work packages from the WBS
can an activity have one or more work packages?
two primary explanations for failure of integrating work packages and network?
diff groups used to define work packages and activities. the WBS is poorly constructed and not deliverable/output oriented
how can managers guarantee continuity?
by having same people that defined the WBS and work packages define the network activities
what are the primary inputs for developing project network plan?
4 things about activities?
element of project that takes time. may or may not require resources. work or wait. represent one or more tasks from a work package
has more than one activity immediately preceding it
activities that can take place at the same time
sequence of connected, dependent activities
paths with longest duration through the network, if an activity on this path is delayed the project is delayed!
has more than one activity immediately following it
3 things about activity-on-node?
one of two methods used to develop project networks. dominates all project plans. activities represented by nodes (boxes).
3 relationships that must be established for activities included in project network?
predecessor, successor, concurrent/parallel
what questions do completion of forward and backward processes answer? (2)
forward pass - earliest times, backward pass - latest times
what does a forward pass - earliest times do?
starts with first project activity and traces each path through the network to last project activity, adding activity times while tracing
what is the longest path that denotes project completion time for plan?
equation of forward pass?
early start + duration = early finish
what does backward pass - latest times do?
starts with last project activity on network and traces backward subtracting activity times
what does the late finish usually equal? (2 things)
early finish or existing project duration deadline
equation of backward pass?
late finish - duration = late start
tells the amount of time an activity can be delayed and not delay the entire project
what tells the amount of time an activity can exceed its early finish date without affecting the project end date or imposed completion date?
likelihood the original critical path will change once project is initiated
characteristics of an INSENSITIVE network schedule?
has one critical path and noncritical activities that enjoy significant slack
