Release and Deployment Management Maturity

Level 1 Level 2 Level 3 Level 4 Level 5Manual Packaged Scripted Complex On DemandBespoke, unpractised process. Authorization and sign off incidental. Roll back via back up copy or scripts.

Some packages (e.g. MSIs) and scripts. Release authorization considered.

Multiple scripts allowing automation. Can deploy to multiple parts of route to live. Possible roll back through redeployment. Some version control.

Can deploy composite applications. Role based security available. Multiple platforms services through single interface.

Push button deployments when code is ready – continuous delivery and deployment achieved. Full auditability and compliance.

CONSISTENCY & VISIBILITY• Create a consistent process across all environments• Validate through development and QA• Obtain ‘license’ to deploy to production

CONTROL & GOVERNANCE• Implement an audited process for deployment• Make all environments visible, but control who can do what

INTEGRATION ACROSS THE LIFECYCLE• Linked data – no more spreadsheets of links and references• Track changes and deploy what is needed at the right time• Create an executable plan and track delivery progress

SHIFT LEFT• Earlier testing• More risk mitigated • Defects cost significantly less to find and fix

REDUCED TEST ENVIRONMENT COSTS• Reduced overhead on physical resources and support• Reduced overhead building test environments

INCREASED QUALITY• More defects fixed; fewer production defects• Integration defects carry the most risk in modern software

solutions. Validate the integration well before end to end testing is possible.

Requirements Management Maturity

Level 1 Level 2 Level 3 Level 4 Level 5Written Requirements

Organized Structured Traced Integrated

Documented and shared, regular collaboration between teams, backup and restore enabled

Formatted consistently, stored and secured. Version tracked and easily accessible to those with rights

Types (e.g. functional/non-functional) are specified. Attributes and prioritization is applied. Querying and filtering is possible.

Determine and track requirements relationships, has a hierachy of requirements: user needs, features and use cases. Coverage analysis reports implemented.

Requirements management fully integrated with software development environment: used directly in design, development, change tracking, testing and PM.

Top Practices Correlated with Deployment Frequency

Continuous DeliveryContinuous delivery ensures that your software is always in a releasable state, turning deployment into a non-event that can be performed on demand.

Use of version control for all production artifactsWhen it’s easy to recreate environments for testing and troubleshooting, throughput goes up.

Top Practices Correlated with Lead Time for Changes

Use of version control for all production artifactsThe ability to get changes into production repeatedly in a reliable, low-risk way depends on the comprehensive use of version control.

Automated testingWith a reliable and comprehensive set of automated tests, you can quickly gain confidence that your code is releasable without lengthy integrations and manual regression testing cycles.

Top Practices Correlated with Mean Time to Recover (MTTR)

Use of version control for all production artifactsWhen an error is identified in production, you can quickly either redeploy the last good state or fix the problem and roll forward, reducing the time to recover.

Monitoring system and application healthLogging and monitoring systems make it easy to detect failures and identify the events that contributed to them. Proactive monitoring of system health based on threshold and rate-of-change warnings enables us to preemptively detect and mitigate problems.
