The objective of this paper is to highlight vertical information transfer in relation to operator involvement in development work and to analyze the information channels utilized. A special focus is put on product, production, organisation and information system development. Data were collected in 14 Swedish companies through interviews with operators, production support, and production management. The study indicated a need of strategies for vertical information distribution. Verbal information channels are mostly used. However, formalized information transfer is needed to better utilize the operators’ knowledge and experience for development work as well as to provide personnel with relevant knowledge required for their work. Information flow may be simplified through IT-systems, intranet, documents and instructions, but it implies strong support from management and adapted working methods.
