Project OS

Project plan, Gantt, WBS, RACI, and a weekly status report. The four fundamentals of project management, rollup-connected on Notion.

What Project OS is

Project OS holds plans, milestones, blockers, and a weekly status report on one Notion page. The exec reads the report on Friday without asking the PM. The team reads the plan on Monday without asking the lead.

You get the four fundamentals of project management, plan, timeline, responsibilities, status, linked by rollups instead of sitting in four different tools.

Why this architecture

Projects fail at the seam between the plan and the status. The plan lives in a Gantt tool, the status lives in a Friday email, and the tasks live in Asana. Three places, three versions of the truth, and every exec asks the PM what changed this week because the plan doesn't update itself.

Project OS makes the plan, the tasks, and the status the same data. When a task shifts, the plan updates. When the plan updates, the status report rewrites itself. The exec opens one page on Friday and sees what changed.

What lives inside

Four databases. Projects holds the top-level project with owner, budget, and due date. Milestones holds the phase breakdown, linked to the project. Tasks holds the work, linked to the milestone and an owner. Status holds the weekly snapshot, auto-written from the task changes that week.

Views: This week, Next week, Blocked 2+ days, Shipped, Friday review. The exec opens the last one. The team opens the first three.

How the week runs

Monday, the team opens This week and sees every task due by Friday. Stuck tasks get flagged on day two, not day seven. Tuesday to Thursday, meetings feed tasks into the database, Claude extracts decisions from the transcripts. Friday, the Status database row auto-writes from the week's changes. The exec reads it.

Week 4, the review page surfaces what shipped, what slipped, and what compounded. Patterns tag into the Playbook for the next project.

What breaks, and how to avoid it

The first failure is tasks without owners. The list grows, nobody finishes, and the Friday status is a wishlist. Fix: every task requires an owner. No owner, no row.

The second failure is status reports nobody reads. Fix: the status page auto-writes from the week's task changes. The exec reads the diff, not a paragraph.

The third failure is scope creep buried in the task list. New tasks keep appearing, old tasks never close. Fix: every task links to a milestone. Tasks without a milestone sit in a triage view the PM clears weekly.
