27 Determining Slack Is the amount of time an activity can be delayed after the start of a longer parallel activity or
activities. Is how long an activity can exceed its early finish date without affecting early start dates of any successor(s). Allows flexibility in scheduling scarce resources. If slack of one activity in a path is used, the ES for all activities that follow in the chain will be delayed and their slack reduced. Use of total slack must be coordinated with all participants in the activities that follow in the chain. After slack for
each activity is computed, the critical path(s) is (are) easily identified. When the LF = EF for the end project activity, the critical path can be identified as those activities that also have LF = EF or a slack of zero. The critical path is the network path(s) that has (have) the least slack in common.
28 Sensitivity The likelihood the original critical path(s) will change once the project is initiated. The critical path is the network path(s) that has (have)
the least slack in common. Sensitivity is a function of the number of critical or near-critical paths. A sensitive network would be one or more than critical paths and/or noncritical activities with very little slack. Under these circumstances the original critical path is much more likely to change once work gets under way on the project. Project managers assess the sensitivity of their network schedules to determine how much attention they
should devote to managing the critical path. 29 Activity-on-Node Network with Slack 30 Practical Considerations Which of the following represents an activity on a project network?Which of the following represents an activity on an AOA project network? Task(s) of the project that consumes time while people/equipment either work or wait. Activity-on-arrow method for drawing project networks. The activity is shown as an arrow.
What is the minimum amount of time a dependent activity must be delayed to begin or end?1) The correct answer is option c) Lag. In project scheduling, Lag or Lag Time is the time that is required to delay to begin or end an activity that is related or dependent to another preceding activity.
Which activities are to be completed immediately following a particular activity?Activities that must follow immediately after an activity are called successor activities. 3. Activities that can occur while an activity is take place is known as a concurrent or parallel relationship.
What sort of activity has more than one dependency arrow flowing from it?Burst Activity: an activity that has more than one activity immediately following it (more than one dependency arrow flowing from it).
