The starter checklist

Tick each one when it is real, not when it is planned.

DoneItemNotes
Done?1. Baseline the book of work so invisible demand stops running the show.
Done?2. Draft intake rules before you accept another hallway yes.
Done?3. Run one scored prioritization pass on a limited set, and make a real fund, pause, or kill call.
Done?4. Pilot one portfolio review that is not a status dump.
Done?5. Calendar the cadence and keep a decision log.
Done?6. Let AI draft the templates and scenario packs. You own every tradeoff.

The 90-day map

Steal the milestones. Adapt the language. Don't paste someone else's org into it.

Days 1-30

Baseline the system

  • One view of the book of work: initiatives that consume real capacity, named, owned, roughly sized.
  • Draft intake rules: who can submit, minimum info, and what “accepted into the queue” means versus “approved to start.”
  • Pick a scoring model stub: the four lenses you will actually score.
  • Name who owns the portfolio review. One accountable human.

AI drafts: inventory templates, first-pass intake criteria, demand themes from a messy backlog. You decide: what counts as in the portfolio, who holds the intake gate, what done means for month one.

Days 31-60

Force the first tradeoffs

  • Run a scored prioritization pass on a limited set you can finish.
  • Stand up a lightweight capacity view. People-weeks or team-slots by month.
  • Pilot one portfolio review: mix, capacity, decisions. Time-boxed. End with written decisions.

AI drafts: scenario packs, scoring sheet drafts, cross-item risk and dependency summaries. You decide: what funds, pauses, or is killed, and which capacity assumptions you defend out loud.

Days 61-90

Make it stick

  • Harden cadence. Calendar it. Keep a decision log.
  • Tighten intake so a yes visibly costs capacity.
  • Publish a one-page portfolio operating rhythm.

AI drafts: cadence checklists, “what changed since last review” briefs, decision log cleanup. You decide: the operating model you keep, what you refuse to automate, next quarter's rules.

Ninety days won't finish the rebuild. It gives you a spine: visible demand, a scoring pass you've actually run, and a cadence that reviews the portfolio instead of replaying project status.

Worked example (fictional)

A fictional mid-size delivery organization: solid project managers, a backlog that never shrinks, and leadership asking for “more portfolio thinking.” No special tools. A shared list and a standing review.

DoneItemNotes
Done1. BaselineSingle list of named, owned, roughly sized initiatives. Found shadow work and two “small” asks that were not small.
Done2. Intake rulesRules drafted. Accepted into the queue does not mean approved to start.
Done3. Scored passScored a limited slice. One fund, one pause, one kill, all written down.
Done4. Review pilotTime-boxed to mix, capacity, and decisions. Ended with written decisions, one of them “defer.”
Done5. Cadence and logMonthly review on the calendar. Decision log started.
Done6. AI drafts, you decideAI drafted the inventory template and intake criteria. The review owner edited and signed off.

If month three still feels messy, that's normal. The win is that tradeoffs are visible and somebody owns the gate.
