Technical Rationale for Reliability Standards
The Advisory Group for the Technical Rationale for Reliability Standards project is developing an approach to separate embedded technical rationale and implementation guidance within Reliability Standards (specifically, within the Guidelines and Technical Basis section) into distinct documents.
The current Reliability Standards template includes a Guidelines and Technical Basis (GTB) section to provide standard drafting teams a mechanism to: (i) explain the technical basis for the associated Reliability Standard (and Requirements therein); and (ii) provide technical guidance for the associated Reliability Standard (and Requirements therein). The ERO Enterprise recognizes that these sections help industry to understand the technology and technical elements in the Reliability Standard. The ERO continues to assess compliance based on the language of the Reliability Standard and the facts and circumstances presented.
With the enactment of the Compliance Guidance Policy, it appears helpful to further clarify the distinction between Implementation Guidance and GTB (or Technical Rationale, as explained below). GTB should focus on technical rationale that assists technical understanding of a requirement and/or Reliability Standard. GTB should not include compliance examples or compliance language, as such information, if needed, should be developed as Implementation Guidance under the Compliance Guidance Policy.
Purpose/Industry Need:

The use of the term “guideline” in GTB has created confusion for some stakeholders on the use of information in this section for guidance in developing compliance approaches. To clarify the intended use of information in this section, and to address that confusion, the Reliability Standards template will be revised to eliminate the GTB section and allow for the creation of a separate document containing the Technical Rationale. The purpose of this project is to further clarify the principles, development, and use of GTB (historically) and Technical Rationale. GTB that already exists in Reliability Standards will be reviewed under these principles when a new version of a Reliability Standard is being drafted and during any Periodic Review process.
