Abstract
In contexts where competition is intense, growth is rapid, innovation is abundant, local conditions are idiosyncratic, and technological options are increasingly complex, the marketing manager needs to understand the dynamic forces that influence the structure of the industry in order to assess the market strategic value. The problems are made even more difficult when much of the information available is qualitative, not quantitative. In order to reduce endless complexities and produce manageable simplicities, the study proposes a workable systems methodology and a holistic frame of reference that allows managers to focus on relevant issues and avoid the endless search for more details, while drowning in proliferating useless information. This paper presents two cases illustrating systems approaches to marketing strategy and decision-making. The purposes are to contrast a qualitative mapping theory building approach and a quantitative group model building approach to help client groups think systemically about marketing dynamics, and to draw out implications for research and practice in marketing strategy.
