Why defining success metrics matters more than it looks

This is one of those topics that looks small until it costs you something. Defining success metrics is easy to treat as a detail, and that is exactly why it is worth a few minutes of attention.

The projects that go badly are rarely the ones with the hardest technical problems. Most teams find the first pass takes an afternoon and the maintenance takes minutes a month.

Why it matters

Agree the numbers before the work starts. The teams that handle this well are rarely the ones with the biggest budgets. The practical test is whether someone new to the project could tell, in a minute, that it had been handled.

Traffic is not a business outcome. This is the sort of thing that compounds, quietly, in both directions. Anything you cannot measure here, you are deciding by taste, which is fine as long as everyone knows it.

Where it usually goes wrong

Pick metrics you can actually influence. It is worth being explicit about, because assumptions differ quietly. It is the sort of thing that looks like polish right up until it costs you an enquiry.

The short version

Clear scope protects the client at least as much as it protects the agency. Three things worth confirming about defining success metrics before you move on:

• Someone can say what the current setup is without going to look
• Pick metrics you can actually influence — and you know whether that is true here
• There is a way to tell whether the last change to this helped

Most of the value here comes from doing the first two things, not all of them.
