What is the relationship of Metrics and Measurement and Quality?

Here are the points to be noted

• Software requirements are the foundation from which quality is measured. Lack of conformance to requirements is lack of quality.
• Specified standards define a set of development criteria that guide the manner in which software is engineered. If the criteria are not followed, lack of quality will almost surely result.
• There is a set of implicit requirements that often goes unmentioned (e.g., the desire for ease of use). If software conforms to its explicit requirements but fails to meet implicit requirements, software quality is suspect.

So there is relationship. As we have measurement correct we will have solid requirements and on that at the quality will be fine

How can achieve high levels of software quality?

High levels of quality are possible by following methods

• Enterprise-wide quality programs
• Quality awareness and training methods
• Quality standards and guidelines
• Quality analysis methods
• Quality measurement methods
• Defect prevention methods
• Testing methods
• User-satisfaction methods
• Post release quality control

Achieving Software Quality

Definition:

“For a software application to achieve high quality levels, it is necessary to begin upstream and ensure that intermediate deliverable s and work products are also of high quality levels. This means that the entire process of software development must itself be focused on quality”
Capers Jones

From above definition we can conclude that
A high quality software only can be achieved when follow software quality assurance .Which says that start from the root and continue all the process till the end of development of a software. Monitor all the activities and fix the issue as it arises.

what is software quality?

There are two definitions by IEEE and ISO.

According to IEEE

• The degree to which a system, component, or process meets specified requirements

• The degree to which a system, component, or process meets customer or user needs or expectations

ISO says:

• The totality of features and characteristics of a product or service that bear on its ability to satisfy specified or implied needs.

What is quality?

Quality

Quality has a lot of definitions. But some famous definitions are


1.It is not the “goodness” or “elegance” but “conformance to requirements".
(Crosby)

2.Fitness for use.
(Juran)
