Project Schedule Management Flashcards
The primary output of breaking down the WBS work packages.
Activity list
The identification of more than one solution. Consider roles, materials, tools, and approaches to the project work.
Alternative analysis
A somewhat unreliable estimating approach that relies on historical information to predict what current activity durations should be. More reliable, however, than team member recollections. Also known as top-down estimating and is a form of expert judgment.
Analogous estimating
The most accurate time-and-cost estimating approach a project manager can use. This estimating approach starts at the bottom of the project and considers every activity, its predecessor and successor activities, and the exact amount of resources needed to complete each activity.
Bottom-up estimating
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.
Control account
A predetermined range of acceptable variances, such as +/-10 percent off schedule. Should the variance exceed this, then project control processes and corrected actions will be enacted.
Control threshold
A schedule compression approach that adds more resources to activities on the critical path to complete the project earlier. Costs are added because the associated labor and sometimes resources (such as faster equipment) cause costs to increase.
Crashing
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 and have no float.
Critical path
These dependencies are the preferred order of activities. Project managers should use these relationships at their discretion and should document the logic behind the decision. They 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.
Discretionary dependencies
The earliest a project activity can be completed. Used in the forward pass procedure to discover the critical path and the project float.
Early finish
The earliest a project activity can begin. Used in the forward pass procedure to discover the critical path and the project float.
Early start
As the name implies, these are outside of the projects 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.
External dependencies
A schedule compression method that changes the relationship of activities. Activities that would normally be done in sequence are allowed to be done in parallel or with some overlap.Can be accomplished by changing the relation of activities from FS to SS or even FF or by adding lead time to downstream activities. However, adds risk to the project.
Fast tracking
An activity relationship type that requires the current activity to be finished before its successor can finish.
Finish-to-finish
An activity relationship type that requires the current activity to be finished before its successor can start.
Finish-to-start
A representation of a project network diagram that is often used for outsourced portions of a project, repetitive work within a project, or a subproject. Also called a subnet.
Fragnet
This is the total time a single activity can be delayed without affecting the early start of its immediately following successor activities.
Free float
The difference between Total Float and Free Float is that Total Float represents the amount of time a task can be delayed without affecting the completion date of the project, while Free Float represents the amount of time a task can be delayed without affecting the start date of its subsequent tasks.
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.
Hard Logic
Internal relationships to the project or the organization. For example, the project team must create the software as part of the projects deliverable before software can be tested for quality control.
Internal dependencies
The time that moves two or more activities further apart.
EX: Waiting for primer to dry before you can paint
Lag time
The latest a project activity can finish. Used in the backward pass procedure to discover the critical path and the project float.
Late finish
Negative time that allows two or more activities to overlap where ordinarily these activities would be sequential. The latest a project activity can begin. Used in the backward pass procedure to discover the critical path and the project float.
Lead time
A percentage of the project duration to combat Parkinson’s Law. When project activities become late, their lateness is subtracted from this.
