What is it?
In a resource-constrained world, time is one commodity that cannot be artificially created or replicated. So how managers organise their day is crucial to their success or failure. It was Henry Minztberg who pointed out four decades ago that a manager's day is in fact a constant series of interruptions - and this was before BlackBerrys, email and other triumphs of new technology. Efficiency and effectiveness: it's about time. Manage your time well and all you have to worry about is the business cycle, customers, colleagues and the competition.
