3. There are plenty CD maturity models

4. Why we needed yet another maturity model
3
• Maturity Models are usually really high level – we wanted to enable
teams to go on the journey themselves
• Maturity models usually don’t really tell you about dependencies, which
we wanted to address to avoid “we do CI, but don’t have automated
tests”
• Maturity models usually don’t tell when you need to coordinate
something centrally and what applications can do on their own
• We didn’t like that the models had reportable levels, we wanted to see
progress not gaining levels

We were inspired by something close to our heart

•CD team have defined a
set of technical
dependencies
(capabilities) required on
the path to achieving
Continuous Delivery
•Foundation capabilities
are at the left. These are
the minimum required.
•The most mature
capabilities are at the
right.
•Yellow are enterprise
dependencies
• Each box comes with
definition and metrics

7. Continuous Delivery is
at the very far right!

8. Continuous Delivery is at
the very far right!
It is a multi-year journey to
achieve this across the
organisation with many
enabling technical
capability pre-requisites.

Telstra CD Technical Capabilities – Current Focus
Focus is on getting
applications to establish
foundation capabilities in:
- Automated Unit
Testing
- Auto Packaging
- Auto Deployments
and collecting baseline
metrics

Key Challenge: How do
you toggle across the
enterprise?

the team involved willchosefrom the
following coverage criteria: function,
statement, branch or condition coverage.
