Quality conformance in HCI consist conformance of requirements and conformance for specification with customer needs and expectations. With respect to HCI, quality is something beyond that. Quality is a predictable degree of uniformity and dependability with the low cost and suitable for the market with the totality (ability to full fill the stated needs/requirements).
Let’s see some general definitions of Quality
- Characteristics or attributes of a System/product which are measurable, things we are able to compare to known standards such as color, length, electrical properties and so on.
- Quality is how much the manufacturer fulfilled the specifications given by the user. Quality is proportional to the conformance of specification
- Specifications are the functionalities of System or a product, or simply “what system provides to the user”
- In software development, Quality is the measured by achievement of requirements. Hence the quality is proportional to conformance of requirements.
- Requirements are the compulsory needs of a user, or simply ” what user expects from a System?”
- Requirements can be further divided into Functional Requirements(FR) and Non-Functional Requirements(NFR).
