“…In line with these findings, Horwitz et al (2003) show the strong motivational importance of what they describe as 'job crafting', or the degree of freedom for individuals to adapt the physical and cognitive elements in the task and relationship boundaries of their work. Within the broad spectrum of motivational measures for knowledge work, the class of incentive and reward systems has received special attention (e.g., Amabile, Conti, Coon, Lazenby, & Herron, 1996;Carson, 2001;Despres & Hiltrop, 1996;Hennessey & Amabile, 1998;Krönig, 2001;Kubo & Saka, 2002;McKenzie et al, 2001;Salo, 2001). Prescriptions for knowledge-friendly reward systems, which are partly backed by research, include that reward systems should be perceived as rational by the individual and the team, that they should focus on insights rather than status and hierarchical position, that they put challenge before monetary compensation, that they should involve an appropriate degree of flexibility and adaptability, and that the drafters of such systems should be aware that rewards can also demotivate because of crowding-out effects.…”
