“…These improvement ideas ease negotiations by helping people to strengthen their existing ideas and make them ready for implementation. To facilitate the divergent and convergent production from the evaluation knowledge, a range of appropriate creativity techniques (Castellano, Davidson, & Khelladi, 2017; Couger, 1996; Couger, Higgins, & McIntyre, 1993; Isaksen & Treffinger, 1985) can be deployed directly. For example, combined hierarchical listing of ideas (e.g., Belkin et al, 1993; Müller‐Wienbergen, Müller, Seidel, & Becker, 2011), text and image stimuli based on qualitative evaluations, and force field analysis (e.g., Couger, 1996; Couger et al, 1993) can be used to facilitate an iterative process of idea evaluation and creative production (e.g., Ulrich, 2018).…”
