It is difficult to influence a system we do not comprehend. That is why when faced with complexity, we feel as though what worked yes- terday no longer works today, as if our hard-earned knowledge is no longer sufficient and, as a result, our confidence slowly slips away. —We have entered the realm of unknowns.— This book will enable you to develop a whole new vocabulary and set of reference points adapted to the reality of complex environments. As you gain these new bearings, you will be able to fully explore the opportunities offered by these unknowns. Comfortable with Complexity is the essential foundation for any leader or individual wanting not only to survive, but also thrive in this fast-changing world.
