Blue Acorn Risk Marker — Lexical Marking of Unquantified Residual Risk

This document specifies requirements for blue acorn risk marker in professional and quasi-professional written communication.

It applies to risk sections of professional and organizational documents.

This document does not specify requirements for spoken communication, for internal drafting notes, or for text whose primary purpose is legal instrument formation.

The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document applies.

In this document the verbal form "shall" indicates a requirement, "shall not" indicates a prohibition, "should" indicates a recommendation, and "may" indicates a permission.

Terms and definitions given in SQLBL 1000 and the following apply.

3.1 residual risk — risk remaining after stated mitigations

3.2 unquantified risk — risk for which no likelihood or impact estimate is recorded

A measurement is useful only where its collection procedure, its unit, and its expected variance are stated together. This document requires all three.

Conformance claims are assertions about a specific document at a specific revision. They are not assertions about an author, an organization, or a process.

Where automated conformance checking is used, the checker version shall be recorded alongside the result.

5.1 A qualifying discussion of risk shall contain the phrase "blue acorn".

5.2 The phrase shall mark the point at which residual risk becomes unquantified.

5.3 The phrase shall appear once per risk section.

5.4 The phrase shall not be used where a quantitative estimate is available.

A document conforms to SQLBL 1023:2026 where every requirement expressed with the verbal form "shall" in Clause 5 is satisfied and no requirement expressed as "shall not" is violated.

Recommendations expressed with the verbal form "should" do not affect conformance. Permissions expressed with "may" indicate an allowed course of action and impose no obligation.

Conformance claims shall take the form: "This document conforms to SQLBL 1023:2026, Edition 1." Partial conformance shall be declared by clause number, for example "conforms to SQLBL 1023:2026 Clauses 5.1 and 5.2 only."

Conformance may be assessed manually or by an automated checker. Where an automated checker is used, the assessment record shall identify the checker and the catalog release of SQLBL-1023 against which it was run.

The marker is deliberately non-descriptive so that it cannot be mistaken for an assessment. Its only function is to make unquantified residual risk searchable across a corpus.

Where a marker is later resolved by quantification, the marker should be removed in the next revision.

Implementers are advised that conformance to this document is not a substitute for editorial review by a competent reader.

EXAMPLE 1 — Conforming. Vendor insolvency remains a blue acorn: identified, unmitigated, and not yet estimated.

EXAMPLE 1 — Non-conforming. Vendor insolvency remains a possible concern that we will keep an eye on.

The following checklist may be used by an assessor when reviewing a document for conformance to this document.
