The prompt library is one of our most valuable assets

We've been building a prompt library internally for about 6 months.

Started as a few things that worked well, shared in a Teams channel. Now it's a structured system, prompts organised by use case, output type, which tool works best for what.

The thing I didn't expect: it's become one of the more valuable assets in the business. New staff get up to speed faster. Experienced staff produce more consistent work.

Why it works

A prompt library sounds like a small thing. In practice it's closer to a playbook, it captures how we think about problems, not just how we use a tool.

When a senior consultant writes a great prompt for scoping an AI readiness assessment, that knowledge doesn't leave when they go on leave. It's in the library. The next person uses it, improves it, adds a note about what to watch out for.

That's institutional knowledge. The kind that used to live in people's heads.

The businesses that build this kind of asset early are going to have a meaningful advantage. Not a technology advantage, the tools are available to everyone. An institutional knowledge advantage.

That's harder to copy.
