Open your browser
and search for DevOps. Your search result is full of a picture (or its
variations) which essentially lists SDLC steps in an eight shape.
Certainly it is a
great picture, but does is depicts DevOps in its full glory? I think it is not.
We need imagery which can depict business as well as technical aspects of
DevOps. I am using two pictures to depict DevOps in its full glory, one each
for Business and Technical audiences in mind.
Let’s talk about
Business audiences first. These audiences have no appetite to divulge into
technical details though love to keep themselves updated about technology and
its effects on the business.
This picture
focuses on customer experience and Market Demand and mechanism to close this
loop via Market feedback and continuous Delivery. To complete this loop, organization focuses in
Continuous Planning, Continuous Integration,
Continuous Deployment & Release, and Continuous
Operations.
To reduce the rework due to security related requirements, security should be
embedded into each and every step of Software Development & Operation. To
reduce the cognitive load on the Development team, security by design paradigm
can be employed. To reduce cost of development & operation and risk Shift
Left paradigm need to be embraced.
Let’s talk about
technical audiences. These audiences are keen to take deep dive into technical
realm. Here the focus is on practices at Application as well as infrastructure
level, Work Item tracking, Integrated Dashboard, Collaboration among
stakeholders, Knowledge repository, Security, and incident management. In the
picture of DevOps for Technical folks, mapping to Business picture is provided
by incorporating Capabilities over Practices and CICD pipeline.
In business
audience focused picture, there are several feedback loops are depicted to
emphasize the continuous feedback mechanism. In Technical audience focused
picture only one feedback loop is depicted to encompass numerous small ones
which results from practices listed below the Pipe. Delivery is achieved with
various small steps, not necessarily in sequential manner.
