This paper explores and maps the strategizing process of family businesses in the state of chaos. The aim is to establish a model that can help all stakeholders to better understand and manage issues arising during change. The model is built around the patterns of five attributes that were identified as ‘most informative’ for strategizing of family businesses in state of chaos. Studies from all over the world suggest that family firms account for the majority of businesses and contribute strongly to the growth of national economies. In every small and medium sized family firm succession is a common phenomenon and it is considered to be one of the most critical issues commonly faced by these firms. In this paper we developed a conceptual model for family business strategizing in the state of chaos. The study was conducted with a Knowledge Based Expert System, the Doctus KBS. We have identified five informative attributes by using the KBS algorithms to map strategy elements in chaotic domains. Patterns can then be built using ‘if, then’ rules, which become a model for Family Business strategy in Chaotic Ecosystems. The most informative attributes describe the new knowledge and experience that has been identified as relevant from strategic perspectives. Family businesses can be thought of as complex systems. Chaos theory ‘proposes a broad set of loosely related theoretical and meta-theoretical orientations to the behaviour of complex (non-linear) systems’. Rejecting the view that systems can be understood in terms of, or reduced to, their constituent elements and the predictable, linear relationships between those elements, chaos theory recognises the complex, unpredictable and dynamic nature of systems. Many researchers come to the conclusion that succession planning can result in significantly improved chances for a business’s continuation. However, based on complexity theory and emergent strategizing, we question this conclusion, and whether planning is really the only option for a successful family business succession. The outcomes of the tentative model demonstrate that identified attributes, in this case (1) Content of succession, (2) Successor is capable of handling assets in the future, (3) Preparation of successor, (4) Preparation of succession strategy and (5) Adequate successor, are to be recognized as patterns for strategy making in the state of chaos. The paper provides a tentative model of strategizing applicable to one specific family business, but based on our experience, we believe that this model could be built for other family businesses as well, as we have noticed similar characteristics in our observation of many family businesses.
