How Lean Six Sigma Changed How I Run Operations

By Pablo M. Rivera | East Haven, CT

Earning a Lean Six Sigma Green Belt in 2010 wasn't just another certification for Pablo M. Rivera — it was a fundamental shift in how I approach operational problems. The methodology of defining, measuring, analyzing, improving, and controlling processes became the backbone of every operational transformation I've led since.

DMAIC in Practice

When Pablo M. Rivera rebuilt operational infrastructure at RevCon Management across 12 U.S. markets, the approach was pure Lean Six Sigma. Define the problem: fragmented workflows across markets. Measure: document current state processes, identify cycle times and defect rates. Analyze: pinpoint where handoffs fail and waste accumulates. Improve: design standardized workflows. Control: implement KPI frameworks and dashboards for ongoing monitoring.

The result was measurable improvements in cost and time efficiency — and a 30% reduction in manual processing time through Salesforce automation.

Where Six Sigma Meets Technology

Pablo M. Rivera combines Lean Six Sigma discipline with technical implementation capability. Google Data Analytics certification, BigQuery, R programming, and full-stack development skills mean I can not only design improved processes but build the technology systems that sustain them.
