What is Quality?
As per the ISO 9126-1 norm, quality alludes to the accompanying arrangement of framework attributes, i.e., usefulness, dependability, convenience, productivity, viability and portability about the item that customers find important. Quality is essential to satisfying customers and winning their commitment so they continue to buy from you later on. A quality characteristic refers to an element that makes a product/ item fit for use. The quality characteristics are grouped into categories called ‘parameters’ of fitness for use.
Two such parameters are:
- Quality of design: The quality of design is related to customer satisfaction by variation in quality of products generally called “grades”.
- Quality of conformance: It is the extent to which the products/items and services conform to the intent of design.

Concept of Quality
Quality has been an age-old concern. The discerning customer in shops and market places has applied quality techniques, prodding and turning fruits and vegetables testing for firmness, freshness and fitness for the purpose of consumption. If the products were not adequate, the purchase would not take place. It has four chief parts, viz., quality organising, quality affirmation, quality control, and quality improvement. Quality management is based on the thing and organisation quality, yet notwithstanding the fundamental assets to achieve it.
Quality is how much an article or element (e.g., interaction, item or administration) fulfils a predefined set of traits or prerequisites. The quality of something can be dictated by contrasting a bunch of innate attributes and a bunch of necessities. The meaning of quality is a particular trademark or characteristic. An illustration of quality is generosity. Quality is a judgment of how amazing a person or thing is. An illustration of quality is an item that will not break without any problem.
Measurement of Quality
Measuring quality allows an organisation to identify the areas of improvement, assess the performance of employees, set clear targets and improve customer satisfaction. Organisations can measure quality against various aspects
such as:
- Failure or reject rates
- Level of product returns
- Customer complaints
- Customer satisfaction (generally measured using the survey method)
- Customer loyalty (repeat purchases or renewal rates)
Organisations use various methods for measuring quality. For example, service organisations measure service quality using methods, such as post-service feedback, in-app surveys, mystery shopping and so on.
However, the following are important points to remember for an organisation while measuring quality:
- Quality is subjective and is based on personal opinion. For example, a particular level of quality can be acceptable to one individual but not to the other.
- All aspects of quality are not tangible; for example, reputation of the organisation.
- Quality keeps on evolving due to factors like improved technology, better materials, new manufacturing techniques, new competitors and so on.
- Although quality has many advantages to the organisation, it also involves certain costs; thus, it is important that the benefits outweigh the costs in the long term.
Cost of Quality
Cost of quality is a strategy for working out the costs organisations cause guaranteeing that items satisfy quality guidelines, just as the expenses of delivering merchandise that neglect to fulfil quality guidelines. Cost of second rate quality (COPQ) is portrayed as the costs identified with giving awful quality things or organisations.
There are three classes:
- Appraisal expenses are expenses brought about to decide the level of conformance to quality necessities.
- Internal disappointment costs will be expenses related to abandons found before the client gets the item or administration.
- External disappointment costs will be expenses related to absconds found after the client gets the item or administration.
Quality-related exercises that cause expenses might be isolated into counteraction costs, examination costs and inner and outer disappointment costs.
