Pick one content-heavy, well-defined group — QA — rework their portal end to end, and come out with two things: a site the team actually lives in, and a design-plus-migration blueprint repeatable across every team. Two principles held it together: every choice had to be scalable, and the new site had to be genuinely easier than the old one. The assumption I was least sure of, I named out loud — that we understood this new way of working well enough to build it. Rather than paper over it, the team found budget to bring on two Microsoft consultants, partly to deepen our grasp of the platform and just as much to make sure everything scaled across the whole company.
