A.15.2:3 - Forces (what the definition balances)

Force	Tension we resolve
Universality vs. domain idioms	One plan concept that fits hospitals, fabs, data centers, and research labs—while honoring local terms.
Commitment vs. flexibility	Plans need enough firmness to coordinate, while remaining easy to update as reality changes.
Intended performer vs. performed-work assignee	Plans may name intended performers; the assignment used for performed work is still checked for the work interval.
Budgets vs. performed resource use	Plans state targets and reservations; A.15.1 and the exact resource-use or ledger pattern govern performed resource-use facts.
Decomposition vs. fulfilment	Plan tasks decompose conveniently; they do not force a shape on performed Work occurrences.
