Requirement engineering (RE) process is becoming a key factor for the success of complex one-of-a-kind products. The RE process is commonly viewed as an early system engineering phase with a major bearing on response time, quality, and cost. This study reports on the knowledge acquisition and sharing for requirement engineering (KARE), approach for requirement specification of one-of-a-kind complex systems. The approach provides a generic view of key RE processes clustered into three groups of activities - requirements elicitation, analysis, and negotiation. The process is supported by a set of knowledge functions aimed at facilitating the requirement engineers in matching customer requirements to product characteristics. At the analysis stage, the customer requirements are transformed into product requirements, which can be compared to existing company knowledge, for example, previous products, technology platforms, and production capabilities. The specified product requirements are then interactively evaluated and negotiated against customer and supplier performance indicators.
