So you want to invest to make your business more efficient. Well, how are you going to quantify the impact of your brilliant decision? Try 'cost savings' 'revenue acceleration' and 'reduced customer churn'. These are the measurable pounds, euros and dollars compared against the original investment cost to determine whether returns are acceptable.
Efficient businesses don't waste money! They run like well-tuned engines and don't carry 'fat'. They are more valuable because they maximise their profits and minimize costs. If a well-run business is asked to spend money on investment - the first question is 'how much will it save', followed by 'for how long?' and finally by 'will it improve our service to the customers?'
