What marketing is about
Many years ago, marketing was supposed to lead to sales by overpromising. Even some brands today still do it. But then, when you underdeliver, you lose. No discussion. It’s much better to manage expectations differently.
If you are realistic about what you can do, and especially, what you can’t do, clients will appreciate it because you know what you are talking about. There is nothing worse in technology teams than sales teams that are not linked to technical teams. Everyone is devoted to the same objective: satisfying client expectations by solving their pains.
So solve a pain. On time. On budget. That’s all.
