Statement

This lightweight procedure applies to individual low risk/impact change and provides steps for service updates and releases of the centrally-provided production services.

Overview

This procedure is meant to cover releases for which it's not necessary to go through a complete planning/testing/deployment phase, typically some low risk and low impact changes.

A Jira ticket coming from CHM is used to orchestrate the complete release and deployment.

Once the release will have been deployed feedback will be added to the Jira ticket and re-assigned to CHM so that they can review it.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", “MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
