It is hard to deny James and Tensibai's sentiments that we are hard to define. I've probably offended a few job interviewers by pointing out DevOps means whatever you want it to mean at the time. Vendors and the press in computing are not very motivated by correctness or conformity so any popular term will get muddied in a similar fashion.
There is ITIL
But that doesn't mean some people aren't trying to create a common language for us to talk about operations and processes. While I haven't seen anyone applying it in the real world, there is ITIL. As Wikipedia tells us:
ITIL, formally an acronym for Information Technology Infrastructure Library, is a set of detailed practices for IT service management (ITSM) that focuses on aligning IT services with the needs of business. In its current form (known as ITIL 2011), ITIL is published as a series of five core volumes, each of which covers a different ITSM lifecycle stage. Although ITIL underpins ISO/IEC 20000 (previously BS 15000), the International Service Management Standard for IT service management, there are some differences between the ISO 20000 standard and the ITIL framework.
ITIL describes processes, procedures, tasks, and checklists which are not organization-specific, but can be applied by an organization for establishing integration with the organization's strategy, delivering value, and maintaining a minimum level of competency. It allows the organization to establish a baseline from which it can plan, implement, and measure. It is used to demonstrate compliance and to measure improvement.
Since July 2013, ITIL has been owned by AXELOS, a joint venture between Capita and the Cabinet Office. AXELOS licenses organisations to use the ITIL intellectual property, accredits licensed examination institutes, and manages updates to the framework. Organizations that wish to implement ITIL internally do not require this license.
All of that sounds really exciting, but because of the licensing there's no way for me to build open source software based on this. If you search for ITIL in github the results are very sparse. Until the licensing model changes I think we're stuck with this state of affairs. Unless W3C or the IETF takes up this sort of challenge there won't be a standard which is available to the community.
