To perform root cause analysis for a flaky checkout flow, you apply structured methods like Five Whys and Fishbone diagrams to trace symptoms to systemic causes. This produces prioritized countermeasures to prevent recurrence.

The best way to document a post-incident investigation for an API returning 500 errors is creating an A3 one-page problem report. It captures the root cause analysis and outlines a PDCA cycle for incremental improvements.

To identify and eliminate process waste in team workflows, you conduct Muda analysis and Value Stream Mapping. These techniques pinpoint inefficiencies and guide small, verifiable improvements that enhance quality over time.

Yes, you can use Five Whys and Fishbone analysis for software architecture decisions. They structure the evaluation of design inefficiencies, helping you trace implementation flaws and produce targeted architectural countermeasures.

You should use a PDCA cycle instead of a standard root cause trace when you need to implement, verify, and monitor incremental fixes over time. It provides a structured plan to measure the impact of applied countermeasures continuously.
