Continuous Delivery maturity model
Agile defies phases
Waterfall
Agile
Watergile? Agilefall?
Is this a problem?
Unachieved goals:
● Unpredictable deliveries
● No visibility into the progress
● Cannot deliver fast
● Building up technical debt
● Quality is put on as an afterthought
Measure working software
● If the software doesn't have to work, you can
always meet any other requirement (Gerald
Weinberg)
● Working software is the primary measure of
progress (Agile manifesto)
Additional benefits with CD?

Errors / problems found earlier
‘Automatic’ traceability
Documentation & visibility into the process
‘Automatic’ historic development
‘Forced’ focus on things you should have done anyway:
automation, testability, DevOps,...

DevOps
● Because the wall between Dev & Operations was a bad
idea in the first place
● When we implement CD, we do a lot of operations work
- that should be reused
● CD can help creating trust between Dev & Operations
● Dev needs the cooperation of Operations to really do

Signs of Continuous Delivery Maturity
Technical debt
Henrik Kniberg: The Solution to Technical Debt http://blog.crisp.

Technical debt
Anything about your code & development environment that slows you down. For example:
●
Unclear, unreadable code
●
Lack of test automation, build automation, deployment automation, and anything else that
could be automated that you do manually today
●
Duplicate code
●
Tangled architecture & unnecessarily complex dependencies
●
Slow, ineffective tools
●
Uncommitted code & long-lived branches (hides problems that will slow you down later)
●
Important technical documentation that is missing or out-of-date
●
Unnecessary technical documentation that is being maintained and kept up-to-date
●
Lack of test environments
●
Long build-test cycle & lack of continuous integration
Why do we have technical debt?
Things are the way they are because they got
that way (Gerald Weinberg)
Well - start changing things!
Self assessment
● Where are we?

Assessment - Maturity Model
Workflow model
3 pains + 3 prouds
Place pains + prouds in workflow + Maturity Model
● Where would we like to be?
○ Workflow model / how-we-work
○ Maturity Model
○ Roles - who takes responsibility for the different
areas?
The end - thank you!
