Point 8 of 9 · The review

What I would not do yet

Restraint is part of the judgment. What I'd deliberately hold off on until measurement and experiments justify it.

No big-bang homepage redesign in production before measurement justifies it. Prototyping a direction offline to de-risk it is encouraged (that's what my prototype is); betting the live homepage on an untested overhaul is not.
No major messaging overhaul before measurement can tell winners from noise.
No new programmatic page types until tracking and templates are clean (avoid scaling fragmentation).
No aggressive multivariate testing before traffic and event quality are validated.
No changes to the assessment app itself. Logged-in territory owned by Product; I focus on web-controlled factors and the handoff.
No compliance-sensitive changes without Legal/Privacy sign-off. Medical claims, disclaimers, consent, and tracking are theirs to approve; I draft and recommend, not ship unilaterally.
