This conceptual paper focuses a methodology for the analysis of performances of enterprises operating in production networks. In order to derive adequate results exclusively the operative perspective of performance analysis is investigated. Operative performance analysis implies the analysis of performances of network members considering a special value-adding-process. The introduced approach is divided into two segments: the value adding process-neutral phases and the value adding process-specific phases. In that context special methodologies for the determination of performance indicators, corresponding parameters, evaluation functions and weightings are focussed. Additionally possible consequences are discussed.
