A service catalog entry should tell a reader what a service does, who is accountable for it, and where operational questions go. Include lifecycle status, dependencies, support boundaries, and links to the authoritative runbook and interface contract. Record a review date so a useful directory does not become a misleading address book.

## Separate ownership from familiarity

A person who last edited a file is not necessarily the service owner. Confirm responsibility with the team and name a role or maintained group instead of relying on one individual's availability. Describe who owns the service's behavior, who operates its infrastructure, and who handles support when these differ. Google's on-call guidance provides context for operational responsibility, but your catalog must reflect your organization's actual arrangement. Include a route for unknown ownership so readers do not circulate an urgent issue indefinitely between plausible teams.

## Fill an entry around a real question

An illustrative entry for a report renderer could say: Purpose: transform approved report requests into downloadable files. Owner: reporting platform team. Support boundary: rendering failures, not authorization policy or upstream source accuracy. Dependencies: request queue and artifact storage. Lifecycle: supported internal service. Runbook: the team's recovery document. This example is fictional; replace every role and dependency with verified information. Avoid publishing internal phone numbers, private incident channels, or access tokens in a publicly accessible copy of the catalog.

1. Identify the owner and the scope of that ownership.
2. Provide a current escalation route appropriate to the document's audience.
3. Link the interface contract, runbook, and architecture overview by descriptive names.

## Review the directory as an operational tool

Test whether an unfamiliar teammate can locate the right contact for a failure spanning two services. If both entries claim the other owns the boundary, resolve that ambiguity before treating the catalog as complete. Add maintenance triggers for team changes, service retirement, and transferred responsibilities. In HTML, make each service heading meaningful and keep crucial details outside wide tables that require horizontal scrolling. A static copy is a snapshot: show its verified date and identify the live source of ownership when a later incident requires current information.
