Before you invest in third-party scripts

Most teams know this matters. Fewer have decided who owns it. Before you spend anything on third-party scripts, it is worth confirming a few things are already true.

Most development decisions are really maintenance decisions wearing a different hat. The version that survives contact with a real deadline is the simple one.

Prerequisites

• You can describe the outcome you want in one sentence
• Someone owns it after the work is done
• Every tag you add is code you do not control
• You have a way to tell whether it worked

Warning signs

Chat widgets and trackers are common performance offenders. Small and consistent beats large and occasional here. Budget a little time for it every quarter and it never becomes a project of its own.

Audit the list twice a year and cut what nobody reads. The teams that handle this well are rarely the ones with the biggest budgets. The failure mode is not doing it wrong, it is doing it once and assuming it stays done.

What this looks like day to day

Code gets read far more often than it gets written, and usually by someone with less context than the author had. Three things worth confirming about third-party scripts before you move on:

• Someone can say what the current setup is without going to look
• Audit the list twice a year and cut what nobody reads — 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.
