We Build in QualityUse Feedback
Avoid Unnecessary WorkLearn what works and what doesn't
Use StandardsConsistency for developersLess Learning Time
Evolve the ProcessDevelop patterns for problem domainsLearn anti-patterns
Use AutomationPick one thing and improve itWork through bottlenecks
Use Standards
Choose standards forNamingStyleCoding practicesDocumentation
Static Code Analysis can catch problemsEnable relevant rulesRemove irrelevant rulesRun this often
Use Version Control
Use Version Control
Use Tests
Test early and oftenMake testing a part of development, not a projectSlowly add testsValidate standardsEnsure specifications metDocument your intentions
Validate with Continuous Integration
Evaluation of code from your VCSEnsures all changes are capturedSpecific versions checked
Independent SystemNo machine dependenciesEnsures repeatable build/release
Consistent ProcessEnsures all steps are completedAvoids human tendencies to skip items
Validate with Continuous Integration
Automated Releases
Automation ensures releases are repeatable and reliableWe can release more often with confidenceReleasing more often means
Release smaller changesLower risk of issuesWe learn to toggle/flag items
Monitoring and Learning
We need feedback on our workIs it being used?Does it perform well?
Gather metrics and measurementsFocus on outcomes not outputsSlowly add new itemsDon't forget to measure the people and the software
Use feedback to drive learningPatternsAnti-patterns
