The math behind overdelivering

Here’s why overdelivering hurts your business. In a math edition.

Paul is about to work on a project for Marie.

In Paul’s head, underpromising and overdelivering will make a sweet deal in Marie’s eyes to:

  • Close the sale
  • Build a good reputation
  • The opportunity to raise prices next time. [Because great work, right?]

It’s the perfect formula… to unprofitability.

→ The promise in Paul’s head: X

BUT

→ The promise in Paul’s mouth: Y

→ Paul tells Marie he’ll deliver Y, which is “10” less of what he expects to deliver (leveraging her ignorance/lack of expertise in the field). He underpromises.
​Y = X – 10

→ Marie’s expectations (the actual promise in Marie’s eyes): Y

→ Paul delivers what he projected at the beginning: Y+10 = X

He underpromised and overdelivered.

Marie is blown away.

But now…

Marie’s normal delivery expectation for further work: X

Marie’s normal price expectation for further work: Y = X – 10

​

She will expect to pay X-10 and will expect deliveries for X.

​

While Paul thinks he’s nailing it, he’s just winning the race to zero.

The way out?

Promise. Deliver. Keep your word. Delight.
