A quality model links together and defines the various software metrics and measurement techniques that an organisation uses which when measured, the approach taken must be sufficiently general for hybrid hardware and software systems. In this work software quality factors that should be taken into account in very large information systems will be considered. Such systems will require a high degree of parallelism and will involve a large number of processing elements. We start by identifying the metrics and measurement approaches that can be used. Many of the quality factors would be applied in similar way for sequential and paralleldistributed architectures, however a number of factors will be investigated which are relevant to the parallel class. In such a system many elements can fail which can have major impact on the system's performance, and therefore it affects the costbenefit factors. Portability and usability are other major problems that need to be taken into account when considering all the relevant factors that affect quality for such environments.
