Certified Lean Six Sigma White Belt Exam Prep

Explore lean six sigma white belt basics, including lean's evolution, the lean framework, eight wastes, just-in-time, standard work, and belt levels.

Master the lean six sigma improvement model by applying seven principles, mapping value streams, eliminating non-value-added waste, and reducing variation with data-driven, customer-focused improvements.

Identify eight types of waste in lean production, including defects, overproduction, waiting, non-utilizing talent, transportation, inventory, motion, and processing.

Identify the eight lean waste types—defects, overproduction, waiting, non utilized talent, transportation, inventory, motion, and extra processing. Learn how training, communication, and process design reduce downtime and maximize value.

Explore how variation affects process performance in lean six sigma, using statistics and histograms to compare routes, reduce noise, and blend lean efficiency with sigma effectiveness.

Learn to solve problems using the PDCA cycle: plan, do, check, and act, driving organizational learning through root-cause analysis, standardization, and daily improvement.

Standardisation through 5S builds a disciplined, high-performance workplace by sorting, setting in order, shine, standardize, and sustain continuous improvement with lean culture and teamwork.

Adopt 5S and standard work to eliminate waste and streamline production for improved efficiency. Build a lean culture through teamwork, discipline, and standardized practices that support continuous improvement.

Explore just in time production, standard work, and pull systems that meet customer demand with minimal inventory, single piece flow, and ergonomic, efficient processes.

Apply the takt time formula by comparing total daily available time to daily customer demand, and work through examples to calculate time per unit.

Explains single piece flow as a continuous, low-inventory production where a unit moves through stations a–e, contrasting push with pull and highlighting lean benefits: faster delivery, lower costs, higher quality.

Embed quality into every product and process, monitor variances, and trigger timely containment and preventive actions to support just-in-time delivery and improvements.

Builds in quality through automation and lean thinking, enabling defect detection without human intervention and immediate stop when issues arise, with a five eyes model guiding root-cause improvements.

Learners will understand how management involvement on the shop floor enables daily improvement through go see and act, gemba walks, and MDI dashboards that track defects and trigger corrective actions.

Apply the dmaic define phase within the lean six sigma white belt framework, focusing on voice of the customer, the project charter, and process mapping to drive measurable improvements.

Learn process mapping, including the sidewalk and functional deployment map, to identify inputs, outputs, and non-value-added activities, and measure performance with baselines and why analysis for root causes.

Learn to use the five whys to probe root causes from a simple speeding scenario to production and software issues, with problem statements, probing why questions, and countermeasures.

Apply Pareto analysis and potato charts to stratify defect data, compare day and night shifts, and identify top error categories—missing data, incorrect data, and mis processed items, with trend insights.

Explore the DMAIC improve phase by applying error-proofing (IOK model) principles to prevent and detect defects, using practical tools such as spell check, formula verification, and dropdown controls.

Master error-proofing with a solution selection matrix that ranks options by weighted criteria, then implement a control plan with action plans and a smooth transition to process owners.

Explore lean Japanese terms such as kaizen (incremental change), continuous improvement, and error proofing, and learn how to identify value, map flow, and pursue perfection toward zero waste.

Explore five lean six sigma belts—white, yellow, green, black, master black—and how each level drives value, reveals waste in the value stream, and enables continuous improvement for customers.
