Start with the business performance problems, not a course catalogue.
Then build reusable standards: templates, accessibility baselines, review workflows, publishing pipelines, so every project after the first one gets cheaper and faster.
Measure from day one, so the function can prove its value.
And plan for AI-assisted production early, because it changes the economics of what a small team can deliver.
That is how I built it at Apple, from a standing start to more than a hundred learning experiences in under three years. The architecture outlived any single course.
