Scope and Non-Scope

HRF is intentionally narrow. Its authority comes from what it refuses to cover.

What HRF Covers

HRF addresses decisions made before:

• RFQs are issued
• suppliers are selected
• designs are frozen
• pilots are approved
• timelines are committed

Specifically, HRF focuses on:

• decision readiness
• assumption exposure
• translation gaps between design intent and physical behavior
• upstream failure injection points

HRF operates at the level of:

• language
• models
• decision structure

What HRF Does Not Cover

HRF does not provide:

• manufacturing instructions
• DFM optimization techniques
• supplier catalogs or rankings
• project management guidance
• execution playbooks
• troubleshooting or root-cause repair guides

HRF does not replace engineering judgment. It makes the conditions around that judgment explicit.

If a problem can only be solved by "working harder," HRF is not the right tool.
