Hierarchy & Budget Contracts

Section goal

Block boundaries, top-down budget contracts, integration milestones, and ownership models that prevent late-stage closure chaos.

How to study this section

1. Start with the topic hub to learn the integration contract.

2. Use mechanism and reports pages to connect contract to metrics.

3. Use debug and worked-example pages for war-room readiness.

4. Close with checklist and PPA impact before closure signoff.

Topics

1. block-budget-contracts/ — Block Budget Contracts

2. hierarchy-abstraction-boundaries/ — Hierarchy Abstraction Boundaries

3. integration-milestones/ — Integration Milestones

4. ownership-risk-matrix/ — Ownership & Risk Matrix

Budget and ownership contracts are technical artifacts, not PM slides.

Reports and artifacts

• budget delta dashboard

• ownership matrix

• milestone health report

• risk register

Mini case study

A timing overrun was solved only after budget ownership moved from shared to single-threaded.

Debug branches

• Validate contract revision

• Check owner signatures

• Audit milestone readiness

Senior review question

Ask: what baseline, owner, and artifact prove this topic is truly closed?
