This presentation was given by Daniel Deogun and Daniel Sawano at the JDays conference, Gothenburg, 2015. The concepts and techniques on how to implement continuous delivery have been around for quite a while and is moving away from the exclusive club of early adopters. The tooling and technology around CD have evolved and allows us to fairly easy implement delivery pipelines and the necessary infrastructure. But why is it that many organizations still seem to struggle? As it turns out, the technical solutions of CD is not where the challenges lie. Instead, the hard part is to transform business processes and workflows to a mindset of continuously delivering value. It also puts new challenges on the individual to adopt a new view on how to develop software. In this presentation, we will look at common pitfalls and challenges in implementing CD, and share our experiences from the trenches.

3. Continuous Integration
“Continuous Integration is a software development
practice where members of a team integrate their
work frequently, usually each person integrates at
least daily - leading to multiple integrations per day.
Each integration is verified by an automated build
(including test) to detect integration errors as quickly
as possible.“
- Martin Fowler, ThoughtWorks

4. Continuous Delivery
“…continuous delivery means making sure your
software is always production ready throughout its
entire lifecycle – that any build could potentially be
released to users at the touch of a button using a fully
automated process in a matter of seconds or
minutes.”
- Jez Humble, ThoughtWorks

5. Continuous Delivery or
Continuous Deployment?
“I see the difference as a business decision about frequency of
deployment into production. Continuous Deployment is
actually deploying every change into production, every day
or more frequently.”
“…continuous deployment implies continuous delivery the
converse is not true. Continuous delivery is about putting
the release schedule in the hands of the business, not in the
hands of IT… any build could potentially be released to
users at the touch of a button using a fully automated
process in a matter of seconds or minutes”
- Martin Fowler, ThoughtWorks

20. Conway’s Law
“organizations which design systems … are constrained to produce designs
which are copies of the communication structures of these organizations”
- M. Conway, 1967

21. Conway’s Law Applied
to Business Value
“Organizations which design IT products are constrained to
produce business value at a rate limited by the organizational
structure”

28. Process
• The only way to know if an idea that
looks good on paper will generate
revenue is to test it on customers
• Release, measure, improve/abort

Hmm… ok, are
they prioritzed?

43. The Risk Reduction -

Business IT
Ehh… sure.
We want them
all!

44. The Risk Reduction -

Business IT
No really, we
need them to
be prioritzed?

45. The Risk Reduction -
Release Dilemma
Business IT
It’s only must
haves. Do em’ all!

46. The Risk Reduction -

Business IT
Ok… then we’ll
do a lot of small
releases

47. The Risk Reduction -

Business IT
What?!? No way!
Last time you did
that…

48. The Risk Reduction -

all systems went
banana and we
lost ££$$€€kr

But…

50. The Risk Reduction -
Release Dilemma
Business IT
No buts … we
need to REDUCE
risk

51. The Risk Reduction -
Release Dilemma
Business IT
and release LESS
often with MORE
features!

52. The Risk Reduction -
Release Dilemma
Business IT
Ehh… wouldn’t
that INCREASE
risk?

53. The Risk Reduction -
Release Dilemma
Business IT
What? No, of
course not. Let’s get
this project started.
Time is money

54. Why is Business Acting
this way?
Big feature sets
Less frequent
releases
