Beyond Statistics : A mindset shift in RCA and DMAIC
Benchmark X360’s Green Belt didn’t just teach statistics—it changed how I approach problems in meetings. The course reframed issues as “variation + process entitlement gaps,” making RCAs more data-driven and less about blame.
The trainer’s use of everyday examples from FMCG, IT, and healthcare made concepts stick far better than traditional case studies. I especially valued the AI-in-DMAIC segment, as it connected Lean Six Sigma with tools I already use, such as ChatGPT and Excel.
