TL;DR
Every project has a date and every plan looks solid on its own. Even so, the same few people, systems, and approval forums turn up in all of them. Each plan is fine. The sum is fiction.
What the paper develops
A portfolio calendar shows when activity is planned. It does not show whether the organization has the scarce roles, skills, attention, and dependency capacity to deliver it. This paper puts the EPMO's attention on active demand and the capacity that constrains it, and gives leaders a way to expose overload, compare tradeoffs, and decide which commitments move, change scope, or wait.
What to do next
Govern real demand against the people and systems you actually have, by role, skill, and dependency. The calendar shows what everyone intends to do. The decision is which work gets the scarce capacity and which work waits.
Inside the white paper
- Why every plan can be sound on its own and the sum still impossible
- How to model the roles, skills, and approval forums that actually constrain delivery
- How to present choices about what waits, instead of one plan that cannot hold
