Performance Domain Method - Estimating Methods

Question 1

Affinity grouping

Answer 1

Estimating Methods - involves classifying items into similar categories or collections on the basis of their likeness. Common affinity groupings include T-shirt sizing and Fibonacci numbers.

PLANNING

Question 2

Analogous estimating

Answer 2

Estimating Methods - assesses the duration or cost of an activity
or a project using historical data from a similar activity or project.

PLANNING

Question 3

Function point

Answer 3

Estimating Methods - is an estimate of the amount of business functionality in an information system. Function points are used to calculate a functional size measurement
(FSM) of a software system.

PLANNING

Question 4

Multipoint estimating

Answer 4

Estimating Methods - Multipoint estimating assesses cost or duration by applying an average or weighted average of optimistic, pessimistic, and most likely estimates when there is uncertainty with the individual activity estimates.

PLANNING

Question 5

Parametric estimating

Answer 5

Estimating Methods - uses an algorithm to calculate cost or
duration based on historical data and project parameters.

PLANNING

Question 6

Relative estimating

Answer 6

Estimating Methods - is used to create estimates that are derived from
performing a comparison against a similar body of work, taking effort, complexity, and uncertainty into consideration. Relative estimating is not necessarily based on absolute units of cost or time. Story points are a common unitless measure used in relative estimating.

PLANNING

Question 7

Single-point estimating

Answer 7

Estimating Methods - involves using data to calculate a single
value that reflects a best-guess estimate. A single-point estimate is opposed to a range estimate, which includes the best- and worst-case scenario.

PLANNING

Question 8

Story point estimating

Answer 8

Estimating Methods - involves project team members assigning
abstract, but relative, points of effort required to implement a user story. It tells the project team about the difficulty of the story considering the complexity, risks, and effort involved.

PLANNING

Question 9

Wideband Delphi.

Answer 9

Estimating Methods - is a variation of the Delphi estimating method where subject matter experts complete multiple rounds of producing estimates individually, with a project team discussion after each round, until a consensus is achieved. For Wideband Delphi, those who created the highest and lowest estimates explain their rationale, following which everyone re-estimates. The process repeats until convergence is achieved. Planning poker is a variation of Wideband Delphi.

PLANNING

Question 10

Backlog refinement

Answer 10

Meeting and Event Methods - the backlog is progressively
elaborated and (re)prioritized to identify the work that can be accomplished in an upcoming iteration.
