Drawing on Deweyan pragmatism and the Science-Technology-Society approach, this ethnographic research aims at understanding the role of experience and ends-in-view when handling a product development activity. The research focuses on doings conceptualised as engineer-artefact reciprocity and contributes to practice-based learning and product development studies. The analysis demonstrates that past activities embodied in experience and materialised in artefacts and, likewise, future activities embodied in ends-in-view influence the handling of an activity differently, resulting in either a derailment of handling the activity, habitual completion or reflective completion of the activity. Derailment occurs when experienced engineers are incapable of achieving a common end-in-view; habitual completion is when engineers form a vague end-in-view and no one challenges this; and past experience combined with the formation of a common end-in-view paves the way for reflective completion of the activity. Only the lastmentioned facilitates engineers to gain new experience and create usable artefacts.
