A.10 Service Delivery: The Deployment Phase
The goal of the deployment phase is to create a running environment. The deployment
phase creates the service in one or more testing and production environments. This envir-
onment will then be used for testing or for live production services.
Sample Assessment Questions
• How are packages deployed in production?
• How much downtime is required to deploy the service in production?
• Are metrics collected about frequency of deployment, mean time to restore service,
and change success rate?
• How is the decision made to promote a package from testing to production?
• Which kind of testing is done (system, performance, load, user acceptance)?
• How is deployment handled differently for small, medium, and large releases?
• If there is a corporate standard practice for this OR, what is it and how does this
service comply?
Level 1: Initial
• Deployment involves or requires manual steps.
• Deployments into the testing and production environments are different processes,
each with its own tools and procedures.
• Different people on the team perform deployments differently.
• Deployment requires downtime, and sometimes significant downtime.
• How a release is promoted to production is ad hoc or ill defined.
• Testing is manual, ill defined, or not done.
Level 2: Repeatable
• Deployment is performed in a documented, repeatable process.
• If deployment requires downtime, it is a predictable.
• Testing procedures are documented and repeatable.
Level 3: Defined
• Metrics for frequency of deployment, mean time to restore service, and change
success rate are defined.
