Schedule Management Flashcards
Project Schedule Management Terms
Activity List
Activity List
The primary output of breaking down the WBS work packages.
Alternative Analysis
Alternative Analysis
The identification of more than one solution.
Consider roles, materials, tools, and approaches to the project work.
Analogous Estimating
Analogous Estimating
Uses a similar project to use as an analogy to create an estimate.
A somewhat unreliable estimating approach that relies on historical information to predict what current activity durations should be.
Analogous estimating is more reliable, however, than team member recollections.
Analogous estimating is also known as top-down estimating and is a form of expert judgment.
Bottom-up Estimating
Bottom-up 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.
Control Account
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
Control Threshold
A predetermined range of acceptable variances, such as +/–10 percent off schedule.
Should the variance exceed the threshold, then project control processes and corrected actions will be enacted.
Crashing
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 labor and sometimes resources (such as faster equipment) cause costs to increase.
Critical Path
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 in the critical path have no float.
Discretionary Dependencies
Discretionary Dependencies
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.
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
Early Finish ( EF )
The earliest a project activity can finish. Used in the forward pass procedure to discover the critical path and the project float.
Early Start
Early Start ( ES )
The earliest a project activity can begin.
Used in the forward pass procedure to discover the critical path and the project float
External Dependencies
External Dependencies
As the 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
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 or by adding lead time to downstream activities.
However, fast tracking does add risk to the project.
Finish-to-Finish
Finish-to-Finish
An activity relationship type that requires the current activity to be finished before its successor can finish.
Finish-to-Start
Finish-to-Start
An activity relationship type that requires the current activity to be finished before its successor can start.
Fragnet
Fragnet
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.
Free Float
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
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 Dependencies
Internal relationships to the project or the organization.
For example, the project team must create the software as part of the project’s deliverable before the software can be tested for quality control.
Lag Time
Lag Time
Positive ( more ) time that moves two or more activities further apart.
Lag is the delay of a successor activity and represents time that must pass before the second activity can begin.
Late Finish
Late Finish
The latest a project activity can finish.
Used in the backward pass procedure to discover the critical path and the project float.
Late Start
Late Start
The latest a project activity can begin.
Used in the backward pass procedure to discover the critical path and the project float.
Lead Time
Lead Time
Negative ( less ) time that allows two or more activities to overlap where ordinarily these activities would be sequential.
Lead is the acceleration of a successor activity. In other words, the second activity can begin (and be conducted in parallel) as the first activity.
Management Reserve
Management Reserve
Management reserveisdefinedas the cost or timereservethat is used tomanagethe unidentified risks or “unknown-unknown” (unknown = unidentified, unknown = risks).
Also, a percentage of the project duration to combat Parkinson’s Law.
When project activities become late, their lateness is subtracted from the management reserve.
Mandatory Dependencies
Mandatory Dependencies
These dependencies are the natural order of activities.
For example, you can’t begin building your house until your foundation is in place. These relationships are called hard logic.
Monte Carlo Analysis
Mandatory Dependencies
A project simulation approach named after the world-famous gambling district in Monaco.
This predicts how scenarios may work out, given any number of variables.
The process doesn’t actually churn out a specific answer, but a range of possible answers.
When Monte Carlo analysis is applied to a schedule, it can examine, for example, the optimistic completion date, the pessimistic completion date, and the most likely completion date for each activity in the project and then predict a mean for the project schedule.
Parametric Estimate
Parametric Estimate
Parametric estimating, a more accurate technique for estimating cost and duration, uses the relationship between variables to calculate the cost or duration.
Essentially, a parametric estimate is determined by identifying the unit cost or duration and the number of units required for the project or activity.
The measurement must be scalable in order to be accurate.
- A quantitatively based duration estimate that uses mathematical formulas & amp; parameters to predict how long an activity will take based on the quantities of work to be completed.
Can be used for both time and cost estimates.
Parkinson’s Law
A theory that states: “Work expands so as to fill the time available for its completion.”
It is considered with time estimating, because bloated or padded activity estimates will fill the amount of time allotted to the activity.
Planning Package
Planning Package
A WBS entry located below a control account and above the work packages.
A planning package signifies that there is more planning that needs to be completed for this specific deliverable.
Precedence Diagramming Method
Precedence Diagramming Method
A network diagram that shows activities in nodes and the relationship between each activity.
Predecessors come before the current activity, and successors come after the current activity.
Project Calendars
Calendars that identify when the project work will occur.
Project Float
This is the total time the project can be delayed without passing the customer-expected completion date.
Project Network Diagram
Project Network Diagram
A diagram that visualizes the flow of the project activities and their relationships to other project activities.
Refinement
Refinement
An update to the work breakdown structure.
Resource Breakdown Structure (RBS)
Resource Breakdown Structure (RBS)
This is a hierarchical breakdown of the project resources by category and resource type.
For example, you could have a category of equipment, a category of human resources, and a category of materials.
Within each category, you could identify the types of equipment your project will use, the types of human resources, and the types of materials.
Resource Calendars
Resource Calendars
Calendars that identify when project resources are available for the project work.
Resource-Leveling Heuristic
Resource-Leveling Heuristic
A method to flatten the schedule when resources are over-allocated.
Resource leveling can be applied using different methods to accomplish different goals.
One of the most common methods is to ensure that workers are not overextended on activities.
Rolling Wave Planning
Rolling Wave Planning
The imminent work is planned in detail, while the work in the future is planned at a high level.
This is a form of progressive elaboration.
Schedule Management Plan
Schedule Management Plan
A subsidiary plan in the project management plan.
It defines how the project schedule will be created, estimated, controlled, and managed.
Soft Logic
Soft Logic
The activities don’t necessarily have to happen in a specific order.
For example, you could install the light fixtures first, then the carpet, and then paint the room.
The project manager could use soft logic to change the order of the activities if so desired.
Start-to-Finish
Start-to-Finish
An activity relationship that requires an activity to start so that its successor can finish.
This is the most unusual of all the activity relationship types.
Start-to-Start
Start-to-Start
An activity relationship type that requires the current activity to start before its successor can start.
Subnet
Subnet
A representation of a project network diagram that is often used for outsourced portions of projects, repetitive work within a project, or a subproject.
Also called a fragnet.
Template
Template
A previous project that can be adapted for the current project and forms that are pre-populated with organizational-specific information.
Three-Point Estimate
Three-Point Estimate
An estimating technique for each activity that requires optimistic, most likely, and pessimistic estimates to be created.
Based on these three estimates, an average can be created to predict how long the activity should take.
Total Float
This is the total time an activity can be delayed without delaying project completion.
Work Package
The smallest item in the work breakdown structure.
JIT Scheduling
Just In Time Scheduling
This approach provides new materials to the job site as the team consumes the current materials. It saves on space on the job site, limits cash outlays, and prevents theft of materials as the materials are only delivered as they are needed and don’t need to be stored and managed at the job site.
