Towards a Reference Model of Software Resources Quality

International standards for software product quality classify software resources as a non-functional requirement for software product. Resources requirements based-standards describe required resources requirements related to software and hardware requirements, in which hardware resources requirements specify requirements relevant to hardware environment in which the software will operate. Whereas, software resources requirements specify sizing and timing requirements required by software product. This paper propose a reference model to identify and measure resources requirements of software product quality based on ISO international standards. The proposed reference model is experimented to present its applicability using the software specifications of an ATM machine to identify and measure the functional size of resources requirements independently from development technology. This measure take place at an early phase of the software development life cycle and used by software project managers as one of the primary inputs for the effort estimation process of software products.
