“Any good strategy involves risk. If you think your strategy is foolproof, the fool may well be you. Execution, too, is uncertain – what works in one company with one workforce may have different results elsewhere. Chance often plays a greater role than we think, or than successful managers usually like to admit. The link between inputs and outcomes is tenuous. Bad outcomes don’t always mean that managers made mistakes; and good outcomes don’t always mean they acted brilliantly.”
