The age old strategy of 'under promise and over deliver' is one that often goes wrong, doesn't it? Have you seen it go wrong in your business? For example - a customer is chasing you for an update on a late order and you give them your best delivery prediction.... only to watch it fall apart and witness your customer getting more and more irritated. Not only are they now angry at you / your business, you're now feeling less than brilliant. So how about these three pointers, should you find yourself in the same position?
