Quality assurance:
All those planned and systematic actions necessary to provide adequate confidence that a product or service will satisfy given requirement for quality is called quality assurance.
Quality control:
The quality of product at every stages of manufacturing can therefore, be ensured by introducing some sort of controlling and monitoring mechanism in the production process. This controlling and monitoring mechanism is regarded as quality control system.
The word quality has multiple meanings. Two of those meanings are critical, namely, product performance and freedom from deficiencies '.
Product performance: Product Satisfaction
In the sense of performance, quality refers to the performance features of a product. Such features are decisive as to product performance and as to product satisfaction. Such features compete with each other in the market place. External customers, especially ultimate users, compare the competing performances. Their comparisons then become a factor in deciding whose product will be bought. Because of the competition in the market place, a primary goal for product performance is to be equal or superior to the quality of competing products.
Freedom from deficiencies: Product Dissatisfaction
The word quality also refers to freedom from deficiencies, which take many forms as late deliveries, customer claims and returns, high rate of rework and even cancellation of sales. These collectively are forms of product dissatisfaction.
Some deficiencies impact external customers and hence are a threat to future sales as well as a source of higher costs. Other deficiency impact internal customers only and hence are mainly a source of higher costs.
For quality in the sense of freedom from deficiencies, the long-range goal is perfection.
