Software quality measurement quantifies to what extent a software program or system rates along each of these five dimensions. An aggregated measure of software quality can be computed through a qualitative or a quantitative scoring scheme or a mix of both and then a weighting system reflecting the priorities.
In software engineering and development, a software metric is a standard of measure of a degree to which a software system or process possesses some property. [1] [2] Even if a metric is not a measurement (metrics are functions, while measurements are the numbers obtained by the application of metrics), often the two terms are used as synonyms.
Functionality, usability, reliability, performance and supportability are together referred to as FURPS in relation to software requirements. Agility in working software is an aggregation of seven architecturally sensitive attributes: debuggability, extensibility, portability, scalability, securability, testability and understandability.
In his presentation "Software Quality Metrics to Identify Risk" [8] for the Department of Homeland Security, Tom McCabe introduced the following categorization of cyclomatic complexity: 1 - 10: Simple procedure, little risk; 11 - 20: More complex, moderate risk; 21 - 50: Complex, high risk > 50: Untestable code, very high risk
It is distinct from software quality assurance which encompasses processes and standards for ongoing maintenance of high quality of products, e.g. software deliverables, documentation and processes - avoiding defects. Whereas software quality control is a validation of artifacts compliance against established criteria - finding defects.
ISO/IEC 9126 Software engineering — Product quality was an international standard for the evaluation of software quality.It has been replaced by ISO/IEC 25010:2011. [1]The quality criteria according to ISO 9126
Software Quality Management (SQM) is a management process that aims to develop and manage the quality of software in such a way so as to best ensure that the product meets the quality standards expected by the customer while also meeting any necessary regulatory and developer requirements, if any.
GQM defines a measurement model on three levels: [7]. 1. Conceptual level (Goal) A goal is defined for an object, for a variety of reasons, with respect to various models of quality, from various points of view and relative to a particular environment.
