Opinions vary as to what defines a “classic” business book. My own opinion is that it offers insights and counsel that are of timeless value. To paraphrase Bernard of Chartres, a 12th century monk, their authors are shoulders upon which each new generation of leaders stands. For example:

Value Migration: How to Think Several Moves Ahead of the Competition
Adrian J. Slywotsky
Harvard Business Press (1995)

Twenty years ago renowned consultant Adrian Slywotsky introduced this smart, practical method for CEOs to evaluate their positions in dynamic markets. He divides the business cycle into three phases that trace the movement of value delivered to the customer.

In the first (“inflow”), a company starts to absorb value from other parts of its industry because its business design is better at satisfying customers’ priorities.

In the second (“stability,”) the company is well-matched to customer priorities.

In the third (“outflow”) value starts to move away from the company’s traditional business toward more effective ways of meeting customer needs.

Slywotsky then explains how leaders can win what he calls “business chess” by identifying changing patterns among customers and competitors. If you think you’re getting too comfortable, read this book and regain your edge.
