The use of DevOps
DevOps is not only for supporting IT, it can also be used to support the business strategy and
to improve business processes.
The intention of DevOps can be to establish the software and IT services supply chain to
support the business and to manage the whole process to maturity.
DevOps 01 Introduction
DevOps Process
M.M. Heegstra

7.
The use of DevOps
The DevOps framework should support business
outcomes directly, not only collaboration with
development and operation for IT services.
The use of DevOps should be evaluated by business
outcome, not by an IT project scope and IT outcome.

DevOps Process
The use of DevOps
DevOps is not a single tools, methodology, skill set or
organization structure.
DevOps is a framework combining all of these for
organizations to establish stream-lined processes to
enable the business to operate faster and react to
changes more quickly.
DevOps can also enable maturity by using the Plan-Do-
Check-Act cycle.

DevOps Culture
DevOps initiatives can create cultural change in
companies by transforming the way Operation,
Developers and Testers collaborate during the
development and delivery processes.
Getting these groups to work cohesively is a critical
challenge in DevOps adoption.

The enterprise system
The enterprise holds both the System of Engagement
(SoE) and the System of Record (SoR).
The SoE is focused on speed and the SoR is focused on
business continuity.
The problem is how the SoR can adapt quickly to
changes to the SoE to maintain business continuity.

Service continuity is an essential part of the warranty

If service continuity cannot be maintained and/or

business, then the business will not experience the
value that has been promised.
Without continuity the utility (fitness for purpose) of
the service cannot be accessed.

The concepts of TPS (Toyota Production
System), which includes JIT and automation, can
help.
JIT means building up a stream-lined supply

And automation means automating as much as
possible and stopping the entire process when a
defect occurs.
