Practice Build management and CI Environments and deployment

Release management Testing Data management Configuration Management

Level 3 – Optimizing: Focus on process

improvement

Teams regularly meet to discuss integration problems and resolve

them with automation, faster feedback, and better visibility

All environments managed effectively. Provisioning

fully automated. Virtualization used if

applicable.

Operations and delivery teams regularly collaborate to

manage risks and reduce cycle time.

Production rollbacks rare. Defects found and fixed

immediately.

Release to release feedback loop of database performance and

deployment process

Regular validation that CM policy supports effective

collaboration, rapid development, and auditable

change management processes.

Level 2 –Quantitatively

managed: Process measured and

controlled

Build metrics gathered, made visible, and acted on. Build s are

not left broken.

Orchestrated deployments managed. Release and

rollback processes tested.

Environment and application health monitored and

proactively managed. Cycle time monitored.

Quality metrics and trends tracked. Non

functional requirements defined and measured.

Database upgrades and rollbacks tested with every

deployment. Database performance monitored and

optimized.

Developers check in to mainlined at least once a day.

Branching only used for releases.

Level 1 – ConsistentAutomated processes applied across whole application lifecycle

Automated build and test cycle very time a change is committed. Dependencies managed, Re-use

of scripts and tools.

Fully automated, self-service push-button process

for deploying software. Same process to deploy to

every environment.

Change management and approvals processes defined

and enforced. Regulatory and compliance conditions met.

Automated unit and acceptance tests, the

latter written with testers. Testing part of development process.

Database changes performed automatically as part of

deployment process.

Libraries and dependenciesmanaged. Version control

usage policies determined by change management process.

Level 0 – Repeatable: Process documented and partly automated

Regular automated build and testing. Any build can be re-

created from source control using automated process.

Automated deployment to some environments.

Creation of new environments is cheap. All

configuration externalized / versioned

Painful and infrequent, but reliable, releases. Limited

traceability from requirements to release.

Automated tests written as part of story development.

Changes to databases done with automated scripts

versioned with application.

Version control in use for everything required to

recreate software: source code, configuration, build and

deploy scripts, data migrations.

Level -1 – RegressiveProcesses

unrepeatable, poorly controlled, and

reactive

Manual process for building software. No management of

artifacts and reports.

Manual process for deploying software.

Environment-specificbinaries. Environments provisioned manually

Infrequent and unreliable releases.

Manual testing after development.

Data migration unversionedand performed manually.

Version control either not used, or check-in happens

infrequently.
