SigmaFlow gives quality managers and operations leaders a structured workspace to run PDCA cycles, map SIPOC, track sigma levels, and eliminate the 8 wastes β all in one place.
Start Free β 3 Projects Included See the ToolsMost teams "do PDCA" in PowerPoint slides and spreadsheets. No structure. No tracking. No sigma scores.
Six months later, the same problem recurs because no one can prove what actually worked.
68%of improvement projects fail to sustain gains beyond 12 months without a formal control system.
SigmaFlow enforces the methodology. Every project has a PDCA wheel, SIPOC map, CTQ tree, 8-waste audit, and sigma score β in one place.
Your team can finally prove that improvements are real, sustained, and measurable.
6Οtarget: 3.4 defects per million opportunities. Track your progress in real-time.
Built around the full DMAIC methodology β not just a checklist app.
Interactive PDCA wheel with cycle phases β Plan, Do, Check, Act. Add tasks per phase, track completion, and run multiple improvement cycles per project.
FreeInput your defect data and SigmaFlow calculates your process sigma level in real time. Visual gauge shows progress toward 6-sigma targets.
FreeDefine Suppliers, Inputs, Process, Outputs, and Customers in a structured 5-column grid. Required for every serious improvement project.
FreeMap customer needs β quality drivers β Critical-to-Quality requirements. Ensures your improvement targets what actually matters to the customer.
FreeAudit your process against all 8 lean wastes: TIMWOODS. Score severity, add examples, track elimination progress across projects.
FreeExport full project data β PDCA tasks, sigma scores, waste findings, CTQ items β to CSV for reporting, audits, or board presentations.
Individual+View all completed PDCA cycles over time per project. Prove continuous improvement with a timestamped audit trail. Required for ISO and QMS audits.
Individual+Programmatic access to the PDCA engine. Build improvement workflows, integrate with Slack or Teams, generate improvement reports automatically.
TeamThe Six Sigma problem-solving framework. Every project in SigmaFlow follows the same structure that Fortune 500 quality teams use.
Problem statement, project scope, customer requirements (CTQ), SIPOC map
Baseline sigma level, data collection plan, process mapping, 8-waste audit
Root cause analysis, PDCA cycle planning, hypothesis-driven improvement
Run PDCA cycles, track actions, measure sigma improvement, iterate
Cycle history log, CSV export for audit, sustained sigma score tracking
Built for teams that take quality seriously.
Quality managers, process engineers, Black Belts running DMAIC on production lines
Clinical process improvement, patient flow, error reduction using lean Six Sigma
COOs and VPs of Ops running formal improvement programs without the consulting fees
Green Belt and Black Belt candidates who need to practice DMAIC on real projects
Engineering and product teams applying Six Sigma to software quality and deployment
Project managers tracking rework rates, safety incidents, and schedule variance
Start free. Upgrade when you need more.
No contracts. Cancel anytime. Data export included on all plans.
I spent 40 years in manufacturing β running plants with 78 industrial robots, $30M Fanuc projects, and 40 vision systems. I hold a Six Sigma Black Belt and Green Belt. SigmaFlow is what I built because every other PDCA tool was either a $50K consulting engagement or a spreadsheet template that nobody actually uses.
Free plan includes 3 full projects β PDCA, SIPOC, CTQ, 8 Wastes, and Sigma tracking. No credit card needed.
