Why version control matters more than it looks

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

Code gets read far more often than it gets written, and usually by someone with less context than the author had. The teams that stay on top of it are the ones who put it on a calendar rather than a wish list.

What it costs to ignore

Small commits with clear messages are a gift to future you. There is a version of this that is over-engineered, and it is worth avoiding. Check it against what you would want a competitor's site to get wrong.

Branch naming conventions cost nothing and prevent confusion. In practice this is a scheduling problem more than a technical one. Write the reasoning down alongside the decision, because the reasoning is what changes first.

The mistakes we see most

If it is not in version control, it does not exist. There is a version of this that is over-engineered, and it is worth avoiding. Assume whoever inherits this will have half your context and none of your patience.

What this looks like day to day

Most development decisions are really maintenance decisions wearing a different hat. Three things worth confirming about version control before you move on:

• Someone can say what the current setup is without going to look
• Small commits with clear messages are a gift to future you — and you know whether that is true here
• There is a way to tell whether the last change to this helped
