QUALITY

“A characteristic or attribute of something” The American Heritage Dictionary defines quality. As an attribute of an item quality refers to measurable characteristics thing we are able to compare to known standards like as length, electrical properties, colour, malleability, and various.  Moreover, software, hugely an intellectual entity which is more challenging to characterize than physical objects.

Never the less the measures of a program’s characteristics do exist.  These properties include cohesion, number of function points, cyclomatic complexity, lines of code and several others discussed in the lecture coming.  When we examine an item based on its measurable characteristics 2 types of quality may be encountered quality of conformance and quality of design.

Quality of design provides the characteristics which designers specify for an item. The grade of tolerances, materials, and performance specifications all contribute to the quality of design. The higher-graded materials are used and tighter tolerances and greater stages of performance are specified by the design quality of a product increases if the product is manufactured according to specifications.

Quality of conformance is the degree that the design specifications are followed during manufacturing again the greater the degree of conformance the higher the level of quality of conformance.

In software development quality of design encompasses specifications, requirements, and the design of the   system. The Quality   of   conformance is   an   issue   focused   primarily on   implementation if   the implementation follows the design and the resulting system meets its needs and performance motive, conformance quality is became high.
