Chapter 6- Project Time Management Flashcards
Activity List
The primary output of breaking down the WBS work packages.
Alternative analysis
The identification of more than one solution. Consider roles, materials, tools, and approaches to the project work.
Analogous estimating
A somewhat unreliable estimating approach that relies on historical information to predict what current activity durations should be. Analogous estimating is more reliable, than team member recollections. It is also known as a top-down estimating and is a form of expert judgement.
Bottom-up estimating
The most accurate time-and-cost estimating approach a project manager can use. This estimating approach starts at “bottom” of the project and considers every activity, its predecessor and successor activities, and the exact amount of resources needed to complete each activity.
Control account
A WBS entry that considers the time, cost, and scope measurements for that deliverable within the WBS. The estimated performance is compared against the actual performance to measure overall performance for the deliverables within that control account. The specifics of a control account are documented in a control account plan.
Control threshold
A predetermined range of acceptable variances, such as +/- percent off schedule. Should the variances exceed the threshold then project control processes and corrected actions will be enacted.
Crashing
A schedule compression approach that adds more resources to activities on the critical path to complete the project earlier. When crashing a project, costs are added because the associated labour and sometimes resources ( such as faster equipment) cause cost to increase.
Critical Chain Methos
A network analysis approach where the deadlines associated with individual tasks are removed and only date that matters is the promised due date of the project deliverable. CCM works to modify the project schedule based on the availability of the project resources rather than on the pure sequence of events, as in the critical path method.
Critical path
The path in the project network diagram that cannot be delayed, otherwise the project completion date will be late. There can be more than one critical path. Activities on the critical path have no float, and it is the path longest path on the network diagram.
Discretionary dependencies
These dependencies are preferred order of activities. Project manager should use these relationships at their discretion and should document the logic behind the decision. Discretionary dependencies allow activities to happen in a preferred order because of best practices, conditions unique to the project work, or external events. Also known as preferential or soft logic.
Early finish
The earliest a project activity can finish. Used in the forward pass procedure to discover the critical path and a float.
Early start
The earliest a project activity can start. Used in the forward pass procedure to discover the critical path and a float.
External dependencies
As a name implies, these are dependencies outside of the project’s control. Examples include the delivery of equipment from a vendor, the deliverable of another project, or the decision of a committee, lawsuit, or expected new law.
Fast tracking
A schedule compression method that changes the relationship of activities. With fast tracking, activities, that would normally be done in sequence are allowed to be done in parallel or with some overlap. Fast tracking can be accomplished by changing the relation of activities from FS to SS or even FF by adding lead time to downstream activities. However, fast tracking does add risk to a project.
Finish-to-finish (FF)
An activity relationship type that requires the current activity to be finished before its successor can finish.
Finish-to-start (FS)
An activity relationship type that requires the current activity to be finished before its successor can start.
Fragnet
A representation of a project network diagram that is often used for outsources portions of a project, repetitive work within a project, or a subproject. Also called a subnet.
Free float
This is the total time a single activity can be delayed without affecting the early start of its immediately following successor activities.
Hard logic
Logic that describes activities that must happen in a particular order. For example, the dirt must be excavated before the foundation can be built. The foundation must be in place before the framing can begin. Also known as a mandatory dependency.
Internal dependencies
Internal relationships to the project or the organisation. For example, the project team must create the software as a part of the project’s deliverables before the software can be tested for quality control.
Lag time
Positive time that moves two or more activities further apart.
Late finish
The latest a project activity can finish. Used in the backward pass procedure to discover the critical path and project float.
Late start
The latest a project activity can start.Used in the backward pass procedure to discover the critical path and project float.
Lead time
Negative time that allows two or more activities to overlap where ordinarily these activities would be sequential.
