A motivational speaker in Gauteng can challenge you to think about customer groups. The data taken by the sales force from its customers must include clear information on the needs of these customers and other decision makers. They must be able to come up with what customers buy most, in what quantities and how often. This information may give a clue as to how much of the goods must be supplied to the market and how often - a behavior that can be substantiated by a motivational speaker in Gauteng.  It should also inform the quantity of the goods and service. For instance, if customers buy more than 20 of 1 litre bottle of milk in a week, management should try to supply bigger bottles of the milk, say 2 litres or 5 litres, which will obviously come at a lower cost.  At the end of the day the issue here is much bigger than milk, but rather about inspirational purposes like a motivational speaker in Gauteng.
