About this app

Ninth Principle is a professional assessment platform for Continuous Improvement managers and Lean practitioners. Evaluate your operational capabilities with structured, evidence-based assessments, anytime, anywhere, even without an internet connection.

WHAT YOU CAN ASSESS

▸ CI Manager Assessment
A rigorous evaluation of your capability to lead enterprise-wide Continuous Improvement. Covers capability building, strategic integration, change leadership, performance measurement, and embedding CI as a permanent management discipline. Rated Advanced (~25 minutes).

▸ Lean Practitioner Assessment
Assess your proficiency across core Lean disciplines: daily accountability, problem solving, visual management, change management, and stakeholder influencing.

Each assessment uses a calibrated Likert scale (1–5 per question). You receive an overall percentage score, category-level breakdowns, and a risk classification (Low / Moderate / High / Critical) so you know exactly where to direct development effort.

INSIGHTS AND PROGRESS TRACKING

Results are never just a number. The Insights screen tracks your performance across multiple sessions, surfacing trend lines and comparative charts so you can demonstrate professional growth over time. Share results with coaches, managers, or leadership to evidence your development journey.
