Criteria (to build): They describe the internal view of the software, as seen by the developer. Notations and procedures provide the ability to trace and assess the impact of proposed changes. SQA is an ongoing process within the Software Development Life Cycle (SDLC) that routinely checks the developed software to ensure it meets the desired quality measures. software quality means measure how well software is designed and how well the software conforms to that design. The requirements to change may occur due to poor understanding of the problem, changes in hardware or software environment, or external economic or political factors.

The notion of divide and conquer approach has been implemented as a standard approach to measuring software quality. But, due to its immature nature, very few frameworks for the evaluation of quality exist. Standard of development also described explicitly and expected or proposed benefit from the software that became developed. Information available from foss projects in three information spaces are presented, and a quality model suitable for use in a foss context is constructed.
