VNSG Executive Council Dinner
Dirk van der Horst from Philips gave an
interesting presentation about DevOps. He
kicked off with the Philips Business System
as the corporate-wide starting point for all
business activity, defining Philips’ prime
business aims, their core and differentiating
capabilities, how Philips operates and what
value must be delivered. As a ‘path-to-value’
example in this respect, Philips positioned
DevOps as an (IT) approach for delivering
sustainable results along a credible route.
DevOps elaborates on the Agile development
approach of quickly building new functiona-
lities together with the business within a
strict and short time-frame, so-called scripts.
DevOps, as the symbiosis of development
and operations, adds the integration
with support and operations to the Agile
concept. It provides a smooth supply chain
from business requirement to productive
solution through a continuous flow of
small, incremental improvements that go
productive via a highly automated test and
deployment process. This high grade of
automation allocates the IT resource primarily
to developing new functionalities rather than
testing and repairing changes. As the content
of the change is rather small the impact on
existing productive systems is limited as well,
which reduces the risk involved. In addition,
requirements together with continuous
feedback during the short development
cycle and automated testing stimulate a zero
defects delivery. With Agile and DevOps as
a continuum the traditional software release
approach virtually disappears.
DevOps is driven by clear user stories, or
epics, for defining the requirements. The
descripted functionality is valuated in story
points. All these user stories together create
a functionality backlog. Based on ‘poker
planning’ the build teams prioritise and define
the content of the build iterations, scripts,
that will eliminate this. A definition of done
defines the planned outcome for each script.
The quality of user stories as well as the role
of the business representative in the team -
the product owner - become crucial for the
effective results of this concept rather than the
availability of enough IT resources. DevOps
makes innovation adoption a business pull
rather than an IT push process. There will
always be large IT changes that need to be
executed as a traditional IT project with a
transformation and migration plan, however
DevOps will become the mainstream to
provide continuous operations based on
continuous deployment.
