Culture & Organization

Silo’d OrganizationFunction-based teams organized by skill setWaterfall-style or lack of development methodologyLow cooperation or power-oriented

Agile AdoptionProduct-based teamsMinimize team boundariesOne backlog per teamAdopt agile methodologiesModest cooperation between team members

Scaled Agile Approach (SAFe or other)Extended team collaborationRemove boundary between dev and opsTeam-driven process decisions and accountability

Cross-team Continuous ImprovementProduct-based teams ownership of application and environmentReliable story pointing and sprint planning

Cross-functional TeamsHigh cooperation and performance-orientedSAFe nirvana

Configuration Management

Manual & Untraceable ConfigurationsConfiguration changes not stored anywhereChanges made manually in most environments

Partially Automated & Traceable ChangesConfiguration changes stored centrally, but not version controlledSome configuration changes done through scripts and templates

Automated & Maintained ConfigurationsConfiguration changes version controlled and templates packaged with the applicationAutomated scripts to make configuration changes on deployment

ContainerizationAll configurations are bundled within the container(s)Application and environment properties are immutableSingle image built and tested in all environments

Container OrchestrationApplications containerized and container orchestration utilized to manage environment-specific propertiesUtilize DRY principles (don’t repeat yourself)

Build, Release, & Deploy

Manual Integration & DeploymentCentralized version controlAutomated scripts for building softwareNightly buildsLittle to no management of artifactsManual deploymentInfrequent and unreliable releases

Continuous BuildsPolling or triggered builds (commit hook)Fail builds if they do not compile and pass unit testsAny build can be re-created from source controlManagement of build artifactsBuilds are not left brokenManual infrequent but reliable releases

Deployment PipelinesBuilds fail if quality standards not metAutomated provisioning of environments & deploymentsStandardized environment templatesStandard deployment process for all environmentsInfrequent but fully automated and releases in any environment

Automated but not Continuous DeploymentsTeam prioritizes keeping codebase deployable over doing new workOrchestrated deploymentsBlue/green deploymentsSomewhat frequent fully automated and reliable releases in any environment

Continuous, Automated DeploymentsZero touch continuous deploymentsFrequent, reliable releases in any environmentDeployments never rolled back, always roll forward

Testing Limited TestingOnly local testingSome unit testingNo integration or black-box testing

Partially Automated TestingAutomated unit testingSome automated integration testsCode analysis Test coverage analysisTest environments that do not match production

Automated Behavior-Driven DevelopmentFully automated integration testsSome component testingBehavior-driven developmentTest environments match production

Automated Functional, Integration, & Quality TestingAutomated component testsFully automated acceptance testsExploratory testingAutomated performance testsAutomated security tests

Testing of Containerized ApplicationsVerify expected business valueDefects found and fixed immediately (roll forward)Tests performed on containersAbility to test scalability of application

Monitoring & Reporting

Basic Monitoring & ReportingBaseline process metricsManual reportingIndividualized logging by application

Automated but not Real-timeMeasure the processStatic code analysisAutomatic reportingCentralized logging
