摘要: Non-functional requirements (NFRs) pose unique challenges in estimating the effort it would take to implement them. This is mainly because of their nature; NFRs are subjective, relative, interactive and tending have a broad impact on system as whole. Nevertheless, crucial, when making decisions about scope software by given resources budget, furnish justifying quantitative analysis based both functional (FRs) NFRs. paper presents meta-model which complements FR dimension with another be used estimation approaches. The deployed extend use COSMIC size measurement method measure NFRs, function size. We report case study demonstrate our approach context.
