Software Quality – Explanation and management

Software Quality Concept

Software quality is concerned with ensuring that the required level of quality is achieved in a software product.

  • Involves defining appropriate quality standards and procedures and ensuring that these are followed.
  • Quality management is particularly important for large, complex systems.
  • The quality documentation is a record of progress and supports continuity of development as the development team changes.
  • For smaller systems, quality management needs less documentation and should focus on establishing a quality culture.Software quality
