Requirements Engineering (RE) is a commencing phase in the systems development life cycle and concerned with understanding and specifying the customer's requirements. RE has been recognized as a complex cognitive problem solving process which takes place in an unstructured and poorly understood problem .context. A recent understanding describes the RE process as inherently creative, involving cycles of incremental building followed by insight-driven econceptualization .of the problem space. This chapter relates this new understanding to various creative process models described in the creativity and psychology of problem solving literature.
A review of current attempts to support problem solving in RE using various design rationale approaches suggests., that their common major wealmess lies in the lack of support for the creative and insight-driven problem solving process in RE. In addressing this weakness, the chapter suggests a new approach to promoting and supporting RE creativity using design rationale. The suggested approach involves the ad hoc recording of rationale to support the creative exploration complemented by a post hoc conceptual characterization of the problem space to support insight driven reconceptualization.
