Different aspect of quality-based SPL cost estimation (qCOPLIMO), a quality-based product line life cycle cost estimation model are discussed. The proposed model include the software quality cost in the SPL business case analysis and it consists of the two cost models, Relative Cost of Writing for Reuse (RCWR) for initial product line development and Realtive Cost for Reuse (RCR) model. RCWR is the added cost of writing software to be most cost-effectively reused across a product line family of applications, relative to the cost of writing a standalone application. RCR is the cost of reusing the software in a new application with the same product line family, relative to developing newly built software for the application. After the initial product is developed using product line engineering practice, the portion or the whole can be used for other products in the same product line. The proposed qCOPLIMO model provides a framework to estimate the effects of software quality cost.
