Theory of constraints
https://en.wikipedia.org/wiki/Theory_of_constraints

Four types of work:
Business projects: backed by dev project, tracked
Internal IT projects: infra, operations, automation, not visible
Operational change: distanced from business projects
Unplanned work: generated from failures, audits, tracked by problem tickets
