What is three-state readiness?
A planning dimension has three states, not two: not assessed, assessed and nothing found, and assessed with items.
Collapsing "assessed, nothing found" into "empty" makes an honest blank indistinguishable from a skipped step, so people invent dependencies and risks to look diligent. Invented entries are worse than blanks: they consume review attention and make the register look trustworthy when it is not.

- Vertical work — A delivery stream owned by a single team or discipline that produces end-to-end value within its own lane — frontend, backend, data, mobile, platform.
- Horizontal work — A cross-cutting concern that pulses into several delivery streams at specific gates — security review, legal, compliance, design, accessibility, privacy.
This definition comes from building DeliverySheet — it takes a vague work request to a clear delivery decision, so the shape, owner, capacity, dependencies and open questions are on the table before anyone commits people or a date.
