This chapter details the imperative to become and remain productive as a constant quest in the lives of mobile knowledge workers. These workers’ accounts highlight three key features of this quest: capturing the elusive knowledge product; crafting and monitoring productivity narratives; and working on the self to become and remain a productive subject. While the achievement of productivity and product creation are central to MKW, it is the all-encompassing effects of ‘the productivity imperative’ that generates the corollary work of narrating productivity that we address in this chapter.
