1588 - Adopting Continuous Delivery at a Large Telco: A Practical Maturity Model Mirco Hering

slides from other deck

There are plenty CD maturity models

2

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

Continuous Delivery is

at the very far right!

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

Feature Toggles

Key Challenge: How do you toggle across the enterprise?

Dependant on everything being in SourceControl

*Depending on each application’s needs, the team involved will chose from the following coverage criteria: function,

statement, branch or condition coverage. Details of what each of these mean can be found in the Definitions and Metrics

document.
