Guide - Section 2.4 (DECK #1) - Planning Performance Flashcards
What is a quantitative assessment
of the likely amount or outcome of a variable,
such as project costs, resources, effort, or durations called?
Estimate
Accuracy vs Precision
Accuracy - assessment of correctness
Precision - assessment of exactness (may not be correct)
What is a Schedule Compression Technique
used to shorten the schedule
for the least incremental cost?
What are the key components of this method?
Project Crashing
1. additional resources required
2. simultaneous tasks running at the same time (requires no dependencies on tasks at hand)
An alternative description is… Project crashing is a schedule compression technique in which you bring in additional resources to complete two tasks simultaneously.
What are some examples of additional resources
used in project crashing? (3)
- adding people
- working overtime
- paying to expedite deliveries
What is meant by “the least incremental cost”?
The least incremental cost is
how much it would cost
to add one additional unit
of product (task) being produced (completed).
What is a schedule compression method
in which activities or phases,
normally done in sequence are performed in parallel
for at least a portion of their duration?
Describe two key components of this method?
Fast Tracking
- does NOT require additional resources
- requires no dependencies between tasks to be completed simultaneously
What often entails applying leads and lags along a network path?
Fast Tracking
What is a lead and when is it used?
A lead is used when fast tracking a project.
It is when the work of a successor activity is accelerated,
typically when it is started before the predecessor has finished.
What is a lag and when is it used?
A lag is a delay of a successor activity. It represents the time gap between the completion of one activity and the start of another.
Used when changing the type of relationship between activities (finish to start, finish to finish, start to start), and then applying a lag.
How are positive and negative lags defined?
Positive lags represent a waiting period between activities
Negative lags represent a situation where the second activity begins before the first one is completed.
What are the possible impacts of lags?
Positive impacts are when lags can help manage (resource allocation) and (sequencing of tasks)
while negative impacts are when lags can lead to errors, rework, or delays in project completion.
When are leads and lags typically identified?
They are typically identified and managed during project planning and scheduling.
When and How should
**Schedule Compression Techniques **
be used?
When a project is not on track to meet a deadline.
Using both techniques together is the best way to expedite project delivery, but you can also use only one technique if necessary. For example, if you don’t have the budget to hire more team members, project crashing may not be possible.
What is a budget in project management terms?
The approved estimate for
- the project
- or any work breakdown structure (WBS) component
- or any schedule activity
What is the purpose of project planning?
Hint (PDAD)
To proactively
develop an approach
to create the project deliverables
