Schedule Flashcards
(81 cards)
Rolling wave planning
An iterative planning technique. Work to be accomplished soon is planned in detail, while work further in the future is scheduled for a higher level.
Leads and lags
Applied to optimize your schedule (Gantt Chart or a critical path method)
Lead time
Amount of time the next activity can be brought forward. Bring them forward to be done sooner.
Lag time
Amount of time the next activity will be delayed. Delay the item and do it later.
Precedence diagramming method (PDM)
The technique used for constructing a schedule that shows how activities are linked and the sequence in which they need to be performed.
Finish to start (FS)
The next activity cannot start until the previous activity has finished.
Start-to-start (SS)
The next activity cannot start until the previous activity has started.
Finish-to-finish (FF)
The next activity cannot finish until the previous activity has finished.
Start-to-finish (SF)
The next activity cannot finish until the previous activity has started.
Parametric estimating
Use a parameter to estimate per item.
Analogous estimating
Estimates using data from a similar activity or project. Frequently used to estimate project duration when there is a limited amount of detailed information about the project.
Bottom-up estimating
Estimating project resources by assigning a value to the lower-level components of the work breakdown structure (WBS). Add them all up and collate an overall budget.
3-point estimating
Uses an average of 3 points - the optimistic estimate, most likely estimate, and pessimistic estimate. (Average divided by 3)
Resource optimization
Used to adjust the planned use of resources to ensure your schedule is on track.
Resource levelling
It can be used when shared resources are over-allocated, such as when a resource has been assigned to two or more activities during the same period. Often pushes out the schedule.
Resource smoothing
Adjusts the activities of schedules. Activities may only be delayed within their free and total float - the critical path isn’t changed.
Critical path
The sequence of activities which determine the shortest possible project duration.
Critial path method
Used to calculate this, using the amount of free float (for an activity) and total float (total schedule flexibility) on different paths.
How is calculating float done?
Forward and backward pass.
What is float?
The difference between late start and early start.
Schedule compression
A technique that is used to shorten or accelerate the schedule duration, without reducing the project scope, to meet schedule constraints, imposed dates, or other schedule objectives.
Schedule crashing
Shortens the schedule duration by adding resources.
Fast tracking
Activities usually done in sequence are performed in parallel.
Law of diminishing returns
states that as additional resources (e.g., labor, time, materials) are added to a project, the incremental gain in output or efficiency will eventually decrease.
