Terry Leahy was chief executive of Tesco. His autobiography was called 'Management in 10 words' and the most important word for him is 'Truth'. Face the truth, face the facts. This is a really important lesson for us. We work in organisations, and all organisations (or at least all the ones I know well) are truth averse - don't admit to any problems in case the newspapers maul you. But without truth there can be no success.
Sometimes, of course, it can be really difficult to discern the truth - the evidence may be sparse, conflicting or obscure. But sometimes the truth is deliberately hidden, with awful and far reaching consequences.
