Adaptability

QUINT2 homepage QUINT2 book

Description

Attributes of software that bear on the opportunity for its adaptation to different specified environments without applying other actions or means than those provided for this purpose for the software in question.

Indicators

1. effort for portability

Mean effort needed to adapt a unit volume of the software product to a different specified platform.

Source: QUINT

Scale: ratio

Validity: ***

Protocol:

1. Specify the hardware and system software of the environments to which the software product needs to be adapted;

2. Measure the portability effort: the effort needed for adaptation to the specified environments;

3. Determine the size of the software product;

4. Calculate the portability effort per unit size of the product, i.e. the sum of the portability effort for the environments, divided by the size of the software product, divided by the number of adaptations to different environments.

Note: This indicator can only be measured by actually carrying out the adaptation.

2. applicable ratio of hardware environment

Applicable ratio of hardware environment without changing the software.

Source: ISO

Note: The number of applicable machines is divided by the number of applicable machines to be established. A higher value is preferred.

3. applicable ratio of OS environment

Applicable ratio of operating system environment without changing the software.

Source: ISO

Note: The number of applicable OS is divided by the number of applicable OS to be established. A higher value is preferred.

4. applicable ratio of data environment

Applicable ratio of data environment without changing the software.

Source: ISO

Note: The number of applicable data is divided by the number of applicable data to be established. A higher value is preferred.

5. applicable ratio of operation environment

Applicable ratio of operation manual and procedure without changing the software.

Source: ISO

Note: The number of applicable manuals and procedures is divided by the number of applicable manuals and procedures to be established. A higher value is preferred.
