Continuous Delivery (CD) is the next step in the evolution of
the software development process. It draws on Agile methodologies,
but surpasses it. CD is changing the way software is delivered and
opening up a whole range of benefits, ranging from greater
adaptability to more reliable products to improved customer
experiences.
But what if CD means sacrificing quality for speed? Does it
really CD lead to both higher responsiveness and higher
reliability? Lets find out if it really enables you to get better
products to your customers more often.Slide-3

What is it?
CD is a methodology that focuses on smaller releases more often
to avoid the issues and bugs that come with large, slow releases.
CD can actually make your software development more agile and more
able to react to changes. CD comes with quicker reaction times,
less risk and more flexible release options. It also identifies
inefficiencies and hidden costs.
Considering the rapid pace of technological innovation, and
consumers rising expectations for quality products, it makes sense
to evaluate and modernize software delivery processes to keep pace
with these developments.Slide-4
scmGalaxy.comHow it works ?
CD, which relies on automated testing in production
environments, integrates Continuous Integration (CI) practices. CI
is an essential component and first step in the CD pipeline. CI has
every developer continually integrate with all other
developers.
A CD methodology continuously tests, analyzes and improves
software quality. Importantly, this happens during all phases of
the development lifecycle, instead of Agiles approach of waiting
until the end. Similarly, it also involves testing and Quality
Assurance throughout the process.
When CD is well executed, it gives organization a vast number of
benefits.Slide-5

releases and higher quality productsShorter time-to-marketSaves
time and moneyImproved ability to react to changing customer needs
and to meet rising expectationsGet faster and more frequent
feedback from usersMore effective troubleshooting and fewer bugs,
since there is less change in each releaseSlide-6

wide impacts, including enhanced collaboration and
communicationEnables quicker responses to changes in markets and

scmGalaxy.comDevOps/BizDevOps and Continuous Delivery
Much more than just combining development and operations, DevOps
is a set of practices aimed at breaking down silos. BizDevOps is
the next phase: it adds in business teams for further integration.
CD therefore is a natural complement to BizDevOps.
One of the benefits of DevOps is its use of CD. But for CD to be
effective, it needs to be adopted beyond just the development and
operations teams. High-performing companies adopt CD practices
across all products and services.Slide-8
scmGalaxy.comContinuous Deployment vs. CDUnlike continuous
deployment, which deploys each change into production on a very
frequent schedule, CD ensures that the software is deployable at
any point during its lifecycle.
You can deploy to users with the push of a button. CD aims to
automate the software delivery lifecycle until right before
production; continuous deployment automatically deploys every code
that passes the tests to production.Slide-9
scmGalaxy.comHow to implement CDIt goes without saying, but the
basics are important when you are first setting up a transition to
CD.You need to evaluate what it will take, as well as review
overall strategies and stakeholders goals.Next, draw up a schedule
of builds and maintenance release cycles; review builds dependency
management; and identify any gaps in technologies, tools and
processes.The next major phase involves CI and further defining the
process. Develop a CI workflow and document the design flow. It
should contain branching strategies, merging strategies,
dependencies and multi-site coordination.Slide-10
scmGalaxy.comHow to implement CDChoose CI technologies and
tools.Determine and document the timing for automation; with test
automation, release cycles are shortened.
Youre almost there! Now its on to the deployment. Key steps
include: breaking down the CI workflow into steps, automating the
software builds, using a CI framework or building an automation
tool to develop the packaging deployment scripts, and consistent
reporting and tracking so as to facilitate troubleshooting.

scmGalaxy.comWhen is Agile a better option than CD?There are
some circumstances where Agile may be more appropriate than CD.
Those circumstances include:
There is no time, ability or budget for automating testingYour
company needs a specific plan and timeframe, as well as clarity on
release dateYour customers value seeing a long-term plan more than
they value regular updatesCompany executives have not yet bought
into scaling up DevOpsYour company is not set up to make the
cultural and technical shifts to CD quite yetProjects that expect
few changesSlide-12
