Bertelsen, Olav W.Nielsen, Christina2017-04-152017-04-151999978-0-306-47316-6Based on the study of unskilled work in a Danish wastewater treatment plant, the problem of formalisation of work is discussed and extended to technical processes Five symmetrical levels of dynamics in complex technical work arrangements are proposed as a tool for understanding the limits of formalisation and for designing formal constructs in such settings.
