Extended viable system model

Abstract

Viable System Model (VSM) is a well-known and widely used concept when working with enterprise as a viable system. However, research shows that VSM does not include all the required elements to correctly model enterprise as a viable system. This paper proposes extensions to VSM which help to model enterprise in a more complete way. The proposal is illustrated using case study of a real company. Authors propose to tie extended VSM to the notion of Enterprise Operating System in future research.
