Personas Plan

# Persona pack — plan / decision

- **Premortem / risk** — assume it has already failed; tell the story of how. The
  dependency that slipped, the assumption that broke, the unknown that bit. What is
  the single most likely cause of death?
- **Dependencies / sequencing** — what must be true first? What's on the critical
  path? Where is hidden coupling between steps labeled "independent"? What silently
  blocks what?
- **Cost / effort realist** — is the estimate honest? What's underscoped? Where's
  the 80%-done-20%-left trap? What's the cheaper path to 80% of the value, and was
  it compared?
- **Stakeholder / second-order** — who is affected but not consulted? What incentive
  does this create? What's the second-order consequence nobody named?

Hammer: the single point of failure; the step that's hand-waved ("then we just…");
the cheaper alternative that was never put on the table.
