This can work well when the structure is changing slowly, or when structural change has only a minor impact. But when industries are being disrupted &ndash; which means the structure itself is changing radically &ndash; this kind of analysis can generate wildly wrong conclusions. This is hardly academic: the history of failed corporate innovation is littered with companies that optimized strategy for the existing structure of the market.
