Programming Portal: SOFTWARE QUALITY ASSURANCE

The quality is defined as “a characteristic or attribute of something”. As an attribute of an item, quality refers to measurable characteristics-things we are able to compare to known standards such as length, color, electrical properties, malleability, and so on. However, software, largely an intellectual entity, is more challenging to characterize than physical objects.

Quality design refers to the characteristic s that designers specify for an item. The grade of materials, tolerance, and performance specifications all contribute to the quality of design.

Quality of conformance is the degree to which the design specification s are followed during manufacturing. Again, the greater the degree of conformance, the higher the level of quality of conformance.

software Quality Assurance encompasses:

A quality management approach

Effective software engineering technology
Formal technical reviews
A multi tiered testing strategy
Control of software documentation and changes made to it
A procedure to assure compliance with software development standards
Measurement and reporting mechanisms

quality is defined as as "a characteristic or attribute of something". As an attribute of an item quality refers to measurable characteristic-things, we are able to compare to known standards such as length, color, electrical properties, and malleability, and so on. However, software, largely an intellectual entity, is more challenging to characterize than physical object.

Nevertheless, measures of a programs characteristic do exist. These properties include

1. Cyclomatic complexity

2. Cohesion

3. Number of function points

4. Lines of code

When we examine an item based on its measurable characteristics, two kinds of quality may be encountered:

· Quality of design

· Quality of conformance
