Question

According to the ISO-9125 standard quality model, match the attributes given in List-I with their definitions in List-II:

List I List II
(a) Functionality (i) Relationship between the level of performance and the amount of resources
(b) Reliability (ii) Characteristics related to the achievement of purpose
(c) Efficiency (iii) Effort needed for improvement
(d) Maintainability (iv) Capability of software to maintain performance

Choose the correct option from the ones given below:

a. (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
b. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
c. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
d. (a)-(i), (b)-(ii), (c)-(iv), (d)-(iii)

Answer 1

The correct answer is option b, where functionality, reliability, efficiency, and maintainability are matched with their respective definitions according to the ISO-9126 standard quality model.

Step-by-step explanation:

Criteria and constraints play a pivotal role in evaluating design quality. The correct answer is option b. Matching the attributes in List I with their definitions in List II according to the ISO-9126 standard quality model:

• (a) Functionality - (ii) Characteristics related to the achievement of purpose.
• (b) Reliability - (iv) Capability of software to maintain performance under defined conditions for a defined period of time.
• (c) Efficiency - (i) Relationship between the level of performance and the amount of resources used under stated conditions.
• (d) Maintainability - (iii) Effort needed to make specified modifications.

Criteria and constraints are key concepts used to evaluate the quality of a design. A criterion is a measurable standard or attribute of a design used to compare different designs and determine which better solve the problem. A constraint is a limitation or condition that must be satisfied by the design.

By matching the attributes given in List-I with their definitions in List-II, we find that:

(a) Functionality matches with (i) Characteristics related to the achievement of purpose

(b) Reliability matches with (ii) Capability of software to maintain performance

(c) Efficiency matches with (iii) Relationship between the level of performance and the amount of resources

(d) Maintainability matches with (iv) Effort needed for improvement
