Annex B: Annex B: concept of operations guidance

Current editionISO/IEC/IEEE 29148:2018, Annex BEdition 3 at DIS ballotNo public change recorded

Annex B is informative guidance on the concept of operations.

What annex B asks

Annex B is informative guidance on the concept of operations. It explains the organization-level view of the intended operation and how it differs from the system operational concept in Annex A. The ConOps describes how an organization assumes and intends an operation, or a series of operations, to run; the OpsCon describes the operation of a specific system or set of systems. The annex helps a reader decide which document they need and what belongs in each.

Annex B is informative. It explains the concept of operations. It adds no requirement and an assessor cannot cite it as one.

Why it matters

The distinction matters because the two documents are often merged and then neither is complete. The ConOps bounds the operating space and the organizational intent; the OpsCon bounds the system. Annex B is guidance, not a requirement, so an assessor cannot cite it as one.

In the public record

No clause level change is public for this unit; the DIS keeps the title and scope, and the requirement text is not released.

What good looks like

Use Annex B to write the organization-level context, then use Annex A for the system concept. Keep the two documents separate where the organization operates several systems. Cross-reference them so a reader can move between the levels.

Evidence an assessor asks for

The assessor will ask which document holds the organizational intent and which holds the system behaviour. A merged document makes the answer ambiguous.

  • ConOps The organization's assumptions and intent for the operation, including the operating space and the capabilities
  • OpsCon The system-level operational concept, written to the Annex A content
  • Cross-reference The links between the ConOps and the OpsCon sections
  • Boundary note A statement of which document holds which decision

Where it commonly fails

  • The ConOps and OpsCon are the same file with two titles
  • The ConOps describes the system, so the organization-level intent is lost
  • Annex B is cited as a requirement in a conformance claim

What to do before the revision

Write a one-page boundary note before drafting either document. It is easier to separate the levels on paper than after both are written.
