Cognitive science is becoming increasingly central within human factors and ergonomics (HF&E) and there has long been a call for a more systemic perspective in the area with a somewhat broader unit of analysis. This paper presents a case study applying the theoretical framework of distributed cognition (DCog), which shows how DCog would offer a more complete understanding of manufacturing within its greater context, including the social, cultural, and material surroundings. This paper aims to characterize and analyse dock assembly of forest machines as a complex socio-technical system from a DCog perspective; focusing on the creation of enacted landscapes in this particular setting. The paper also exemplifies benefits of using the DCog framework in the manufacturing domain as a way of grasping the assembly workers' tacit competence and skills.
