Norros, Leena, Norros, Ilkka, Liinasuo, Marja and Seppänen, Kari (2011): Impact of human operators on communication network dependability. In: Proceedings of the 2011 Annual European Conference on Cognitive Ergonomics 2011. pp. 35-42.

“Motivation -- To shed light on the context and content of the human operators' work in maintaining the dependability of telecommunication networks. Research approach -- A case study was accomplished in a large telecommunication company. The research focused on clarifying the impact of human operators on the dependability of telecommunication network. Findings/Design -- Interviews confirmed earlier assumption among members of the Communication Network Operations (CNO) community that the human operator has an important impact on the network dependability. Specific sources of errors in daily work were identified and strategies of avoiding erroneous action were described. Moreover we defined generic control demands of the CNO work domain, and operators' ways of coping with these demands. Research limitations/Implications -- The study was restricted to one Finnish telecommunication company. This limits possible empirical generalisation of the findings. Originality/Value -- There is a scarcity of scientific literature about the characteristics of the control work and its demands in this critical domain. Take away message -- Regarding human dependability of communication network operations, a combination of resilient and proactive ways of acting is needed. Due to daily changes in the network and the continuous increase of its complexity, specifically change management on both organisational and work practice levels is required.”
