SCHEDULE 3 Flashcards
The estimate activity duration process requires an estimation of the amount of ____ ____ required to complete the activity and the amount of ____ ____ estimated to complete the activity.
WORK EFFORT; AVAILABLE RESOURCES
A change to a driving resource allocated to the activity will usually have an effect on the duration, but this is not a simple ____ ____ or ____ ____.
“STREIGHT LINE”; LINEAR RELATIONSHIP
When one factor (e.g. resource) used to determine the effort required to produce a unit of work is increased while all other factors remain fixed, a point will eventually be reached at which additions of that one factor start to yield progressively smaller or diminishing increases in output.
LAW OF DIMINISHING RETURNS
Increasing the number of resources to twice the original number does not always reduce the time by half, as it may increase extra duration due to risk, and at some point adding too many resources to the activity may increase duration due to knowledge transfer, learning curve, additional coordination, and other factors involved.
NUMBER OF RESOURCES
This may also play an important role in determining duration estimates. For example, an increase in the output of a manufacturing plant may be achieved by procuring the latest advances in technology, which may impact duration and resource needs.
ADVANCES IN TECHNOLOGY
The project manager also needs to be aware of Student Syndrome - or procrastination - when people start to apply themselves only at the last possible moment before the deadline, and Parkinson’s law where work expands to fill the time available for its completion.

EXPERT JUDGEMENT, ANALOGOUS ESTIMATING, PARAMETRIC ESTIMATING, THREE-PINT ESTIMATING, BOTTOM-UP ESTIMATING, DATA ANALYSIS DECISION MAKING, MEETINGS
A technique for estimating the duration or cost of an activity or a project using historical data from a similar activity or a project.
ANALOGOUS ESTIMATING
Analogous estimating is generally less costly and less time-consuming, but it also ____ ____.
LESS ACCURATE
Parametric estimating uses a ____ ____ between historical data and other variables (e.g., sq. footage in construction) to calculate an estimate for activity parameters, such as ___, ____, and ____.
STATISTICAL RELATIONSHIP; COST, BUDGET, DURATION
Three-Point Estimating helps define an approximate range for an activity’s duration, is used when there is ____ ____ data or when using ____ data.
INSUFICIENT HISTORICAL; JUDGEMENTAL
tE = (tO + tM + tP) / 3. Define Variables in formula:
tE - TRIANGULAR DISTRIBUTION; tO - best-case scenario activity duration; tM - Most likely activity duration; tP - worst-case activity duration
