Readiness level guides

A product is ready when the technology works, it can be made, the parts work together, there is a market, and people can use it safely. Each of these has its own scale.

• TRLTechnology readiness levels (TRL 1–9)Does the technology work, and where has that been shown?
• MRLManufacturing readiness levels (MRL 1–10)What each manufacturing readiness level means, the nine MRL threads, how supply chain readiness is built into MRL, and how to assess MRL with evidence.
• IRLIntegration readiness levels (IRL 1–9)What each integration readiness level means, how IRL combines with TRL into a system readiness level, and how to assess the interfaces in your product.
• CRLCommercial readiness index (CRI 1–6) and adoption readiness levels (ARL)What each commercial readiness index level means, how the US DOE's adoption readiness levels work, and how to assess commercial readiness alongside TRL.
• HRLHuman readiness levels (HRL 1–9)What each human readiness level means, how HRL tracks alongside TRL, and how to evidence that people can use, operate and maintain your product safely.
• ALLBalanced readiness: keep your readiness levels in stepWhy retiring one type of risk faster than the others is a trap, and how to keep every scale aligned.
