Whatever you plan on doing for your customer, never give away your whole strategy.
What is your timeline for service? Double it.
What promises do you make? Make them as generic as possible.
What strategies do you have? Keep them quiet.
When you tell your customer – anything – they expect it. If you don’t deliver, they become unhappy. Yet if your customer has only a vague understanding of what you deliver, your chances of making them happy increase drastically. For example, if you can normally deliver your product in 2 weeks to 90% of your clientele, telling your client 4 weeks will provide you extra time on those few rare exceptions. And it will make those 90% very happy when you deliver 2 weeks early. So happy they will remember you!
