3.1

application asset

output of a specific application engineering process (e.g. application realization) that may be exploited in other lifecycle processes of application engineering and may be adapted as a domain asset (3.3) based on a product management decision

3.2

commonality index

index that captures the level of commonality of a feature, subsystem, component or a product line

Note 1 to entry: Commonality index is calculated as a formula such as measure (3.4) or combination of measures (function). The formula for calculating the commonality index reflects the relative size, effort, complexity, or importance of features, subsystems, components, or a product line as weights.

Note 2 to entry: Function points is one of the candidate cost estimation methods used to calculate efforts required for establishing core assets or product line development. A commonality index is used in conjunction with a function point.

Note 3 to entry: Annex A elaborates on the meaning of commonality and commonality index of the product line.

3.3

domain asset

output of domain engineering life cycle processes that can be reused in producing products during application engineering

[SOURCE:ISO/IEC 26550:2015, 3.11, modified — The alternative preferred term"core asset" and notes to entry have been removed.]

3.4

measure

variable to which a value is assigned as the result of measurement (3.5)

Note 1 to entry: The term"measures" is used to refer collectively to base measures, derived measures, and indicators.

3.5

measurement

set of operations having the object of determining a value of a measure (3.4)

Note 1 to entry: Measurement can include assigning a qualitative category such as the language of a source program (ADA, C, Java, etc.).

[SOURCE:ISO/IEC 25000:2014, 4.20]

3.6

variability index

index that captures the level of variations across features, subsystems, components, products, or product lines

Note 1 to entry: Variability index is calculated as a formula such as measure (3.4) or combination of measures (function). The formula for calculating the variability index reflects the relative size, effort, complexity, or importance of features, subsystems, components, or product lines as weights.

Note 2 to entry: Function points is one of the candidate cost estimation methods used to calculate the additional efforts required for product development. A variability index is used in conjunction with a function point.

Note 3 to entry: Annex A elaborates on the meaning of variability and variability index of the product line.
