DevOps Foundations
- DevOps
- A mindset, culture, and set of technical practices that unite development and operations to deliver value continuously, improving the flow of value from idea to production.
- Business Value of DevOps
- DevOps accelerates time-to-market, improves quality and stability, and enables faster feedback, directly supporting strategic business objectives.
- Culture of Shared Responsibility
- DevOps breaks down silos so development, operations, security, and the business share responsibility for the full spectrum of solution delivery.
- Idea to Cash / Concept to Cash
- The full flow of value from an initial idea through development and delivery to realized business value; DevOps optimizes this end-to-end flow.
CALMR
- CALMR Approach to DevOps
- SAFe's DevOps approach: Culture (shared responsibility), Automation (of the pipeline), Lean flow (small batches, limited WIP), Measurement (of everything), and Recovery (low-risk releases and fast recovery).
- Culture (CALMR)
- Establishing a culture of shared responsibility across development, operations, and the business so people collaborate to deliver and operate solutions.
- Automation (CALMR)
- Automating the continuous delivery pipeline — builds, tests, deployments — to increase speed, repeatability, and quality, while avoiding automating broken processes.
- Lean Flow (CALMR)
- Optimizing flow with small batch sizes, limited work in process, and short queues to reduce lead time and expose bottlenecks.
- Measurement (CALMR)
- Measuring the full pipeline — flow, quality, and business outcomes — to make bottlenecks visible and guide improvement decisions.
- Recovery (CALMR)
- Designing for low-risk releases and fast recovery from failures, so teams can deploy frequently with confidence and minimal blast radius.
Continuous Delivery Pipeline
- Continuous Delivery Pipeline (CDP)
- The workflows, activities, and automation that deliver new functionality: Continuous Exploration, Continuous Integration, Continuous Deployment, and Release on Demand.
- Continuous Exploration (CE)
- The pipeline stage focused on understanding customer needs and defining what to build — hypothesis, research, architecture, and backlog — gaining alignment before development.
- Continuous Integration (CI)
- The pipeline stage where developed changes are frequently integrated, built, and tested to ensure quality and that the system always works.
- Continuous Deployment (CD)
- The pipeline stage that automatically moves validated changes to production-like and production environments, reducing time-to-market and deployment risk.
- Release on Demand
- Releasing value to customers when the business needs it — all at once, staggered, or continuously — decoupled from the development cadence.
Value Stream & Flow
- Value Stream Mapping
- Mapping the steps value takes through the delivery pipeline from idea to cash to measure flow, expose delays and handoffs, and identify bottlenecks to remove.
- Bottleneck Identification
- Finding the constraint that most limits flow in the pipeline and focusing improvement there for the greatest impact.
- Lead Time & Process Time
- Lead time is total elapsed time through a step (including waiting); process time is active work time. Their ratio reveals flow efficiency and waste.
- Percent Complete and Accurate (%C/A)
- A flow measure of how often work passed downstream is usable without rework, highlighting quality problems that disrupt flow.
- Deployment vs. Release
- Deployment moves code to production; release exposes features to users. Separating them (e.g., with feature toggles) enables safe, on-demand release.
Quality & Security
- Continuous Testing
- Building automated testing into every stage of the pipeline so quality is verified continuously rather than inspected at the end.
- Continuous Security (DevSecOps)
- Integrating security practices and controls throughout the pipeline so security is built in continuously rather than bolted on late.
- Test Automation
- Automating tests to enable fast, reliable feedback and frequent integration, a prerequisite for continuous delivery.
- Version Control & Trunk-Based Development
- Managing all changes in version control with practices that support frequent integration and small batches, reducing merge risk and improving flow.
Tools & Investment
- Selecting DevOps Tools Strategically
- Choosing skills and tools based on where they most improve flow and outcomes, rather than adopting technology for its own sake.
- Prioritizing for Economic Benefit
- Sequencing DevOps investments and solutions to deliver the greatest economic benefit first, using flow and value as the guide.
- Automating the Toolchain
- Connecting build, test, deploy, and monitoring tools into an automated pipeline to reduce manual effort, errors, and delay.
Implementation
- DevOps Transformation Plan
- A multi-phased, tailored plan to improve the delivery pipeline, sequencing changes to people, process, and technology for measurable results.
- Implementation Plan (Taking Action)
- The concrete set of next steps attendees leave with to improve their delivery pipeline and the knowledge needed to support and sustain the plan.
- Working Across Roles and Levels
- Engaging all roles and organizational levels to continually optimize the value stream, since DevOps improvement is a shared, cross-functional effort.
- Avoiding Automating Broken Processes
- Improving and simplifying a process before automating it, so automation amplifies value rather than locking in waste.
- Relentless Improvement of the Pipeline
- Continuously measuring and improving the delivery pipeline so flow, quality, and time-to-market keep getting better over time.
