Within this chapter, which is the heart of this book, we now look at some of the key dynamic tools which we can draw on to develop dynamic competitive strategy. I begin with what is called in science and mathematics, “vector analysis,” which enables us to do a “deep-dive” into the outer layers of the “strategic onion” (PEST, growth drivers, Porter’s, to give overall environmental attractiveness). I then take you on a journey through a variety of dynamic curves of different variables over time; for instance the market attractiveness over time, and the competitive advantage over time. There are also some further models that are drawn from systems thinking, such as interdependency models – e.g. for Porter’s Five Competitive Forces and for competences.
