6 - Schedule Management Flashcards
Activity List
Primary output of breaking down the WBS work packages
Alternative Analysis
Identification of more than one solution.
Consider: roles, materials, tools, approaches to project work.
Analogous Estimating
Like an analogy.
Estimating approach that relies on historical information (expert judgement).
Unreliable but fast. More reliable than team member recollections.
aka top down estimating
Bottom-up estimating
Estimating approach where you start at the bottom and estimate time for each activity., its predecessor and its successor.
Most accurate time-and-cost estimating.
Control account
A management control point where scope, budget, and schedule are integrated and compared to the earned value for performance measurement.
A WBS entry that considers time, cost, scope meaurements for that deliverable. Above Work Package in hierarchy.
Estimated performance compared against actual performance to measure overall performance for the deliverables within that control account.
Specifics documented in control account plan.
Control Threshold
Predetermined range of acceptable variances e.g. +/- 10%.
If variance exceeds this, project control processes and corrected actions enacted.
Crashing
Scheudle compression where more resources are added to complete project earlier.
Added costs. Law of diminishing returns could apply here.
Critical path
The path in the network diagram that cannot be delayed otherwise project completion will be late.
Activities in critical path have no float.
Discretionary dependencies
Preferred order of activities.
PMs should use these relationships at their discretion and should document logic.
Allow activities to happen in preferred order because of best practices, conitions uniqyue to project, or external events.
AKA preferential or soft logic.
Early Finish
Earliest an activity can finish. Used in forward pass procedure to discover the critical path and the project float.
top right in network diagram node.
Early start
Earliest an activity can begin. Used in forward pass procedure to discover the critical path and the project float.
Top left in network diagram node.
External dependencies
Dependencies outside project’s control.
e.g. decision of committee, delivery of equipment, etc.
Fast-tracking
A schedule compression method that changes relatioships of activities.
Sequential activities allowed to operate in parallel or with overlap.
FS to SS or FF, or by adding lead time to downstream activities.
Added risk.
Finish to finish
FF
Activity relationship that requires current activity to be finished before the successor can finish.
Finish to start
FS
Activity relationship:
current activity must finish before successor can start.
Fragnet
Representation of project network diagram that is often used for outsourced portions of a project, repetitive work within a project, or a subproject.
AKA subnet
Free float
Total time activity can be delayed without affecting early start of its immediately successor activities.
Hard logic
Logic that described activities that must happen in a particular order.
e.g. excavate before foundation.
aka mandatory dependancy.
