Assessments - The Practice of Cloud System Administration - page 435

• If there is a corporate standard practice for this OR, what is it and how does this
service comply with the practice?
Level 1: Initial
• The process is undocumented and haphazard. Results are inconsistent.
• The process is defined by who does something, not what is done.
• Requests get delayed due to miscommunication, lack of resources, or other avoid-
able reasons.
• Different people do the tasks differently.
Level 2: Repeatable
• The processes required to deploy or decommission a service are understood and
documented.
• The process for each step is documented and verified.
• Each step has a QA checklist to be completed before handing off to the next step.
• Teams learn of process changes by other teams ahead of time.
• Information or processing needed by multiple steps is created once.
• There is no (or minimal) duplication of effort.
• The ability to turn up new capacity is a repeatable process.
• Equipment erasure and disposal is documented and verified.
Level 3: Defined
• The SLA for how long each step should take is defined.
• For physical deployments, standards for removal of waste material (boxes, wrap-
pers, containers) are based on local environmental standards.
• For physical decommissions, standards for disposing of old hardware are based on
local environmental standards as well as the organization's own standards for data
erasure.
• Tools exist to implement many of the steps and processes.
Level 4: Managed
• The defined SLA for each step is measured.
• There are feedback mechanisms for all steps.
• There is periodic review of defects and reworks.
