Could be better

How can you tell if you're not getting the full benefit from your efforts?

Existence doesn't equal effectiveness.

Just because money is being spent on the existence of something, it does not mean that its existence is delivering all that it could.

Marketing is a good example of this; ticking the box is not proof of getting bang for your buck.

How can you tell if it could be better?

There are two ways to tell.

  1. Stop doing it and see what happens when it's not there.
  2. Do it differently and measure the result.

In both cases, simply continuing t0 do what has always been done will mask any attempt to understand if it's working or not, and will hide the fact that opportunity is being sadly wasted.

Could be better? - yes, almost certainly.
