What's your quality standard for good software?

“Works as expected or better” which when broken down into high level buckets: 1. Zero blocker bugs found in production 2. Easy to navigate/self-explanatory UI ( caveat: complicated systems’ UI may be difficult to understand without training non SMEs which may be acceptable ) 3. Meets pre-defined necessary requirements including uptime, scalability, reliability & performance metrics 4. Easy to maintain and expand - follows team/org standards for code quality & testing etc

Good software solves a real problem, delivers a great user experience, remains reliable at scale, and is easy for teams to understand, improve, and maintain over time.
