Does the platform actually work for people?

Usability and learning effectiveness get conflated constantly, and the conflation always runs the same direction: people liked it, therefore it worked. It does not follow. A training tool can be pleasant to use and teach nothing, or be awkward and teach a great deal. Keeping these studies in a series of their own is how we stop one kind of evidence from quietly standing in for the other. What the platform does to competence is a different question, answered by different work - the Digital Twin series covers how that assessment is built, and the validation study will report on whether it holds up.
