It Is a Discipline **[Medium](https://daily.dev/sources/medium_js)** · 11 min read · 2 upvotes · 0 comments ## Summary Reliability in software systems is not a feature to be built once but a discipline embedded in how teams work. Most production problems stem from poor design and preventable bugs — both process failures, not people failures. The author outlines a practical framework covering: aligning on design before writing code (using ADRs and RFCs), choosing simplicity as a reliability decision, building code quality through reviews and automated tests, treating observability and security as first-class from day one, using feature toggles for safer deployments, planning for load and abuse on exposed services, maintaining runbooks and on-call documentation to avoid single points of knowledge, and addressing technical debt by targeting the biggest pain point one at a time. Post-mortems should be blameless and feed improvements back into the process. The core principle throughout: match the weight of process steps to the weight of risk. ## Full article daily.dev links to this article rather than hosting it.
