Free Lean Tools

Visualize manual, auto, walking, and waiting time against takt time. Draw timelines, add work elements, and export print-ready documents.

Map your work area layout, trace the operator walking path, mark quality checks and safety points, and record takt/cycle metrics. Export print-ready charts.

Calculate machine capacity per shift, identify bottleneck processes, and document tool change impacts. The foundation for standardized work analysis.

Record 10 observation cycles per work element, identify the lowest repeatable time, flag outliers, and export print-ready study forms.

Map material and information flow across your value stream. Identify the gap between lead time and processing time. Includes manufacturing, healthcare, and insurance examples.

Ishikawa diagram for root cause analysis. Map causes across Man, Machine, Material, Method, Measurement, and Environment, then drill down with 5-Whys to reach root causes.

Sort problem categories by frequency and overlay a cumulative line to find the "vital few" causes behind most of the effect. Set an 80/20 focus threshold, edit your own counts, and export print-ready charts.

Calculate Overall Equipment Effectiveness from availability, performance, and quality inputs. Identify your biggest loss category and get actionable improvement guidance.

Calculate takt time from available time and customer demand. Add workstations to compare cycle times against takt with a visual bar chart — find bottlenecks and balance your line.

Score your workplace across Sort, Set in Order, Shine, Standardize, and Sustain. 25-item manufacturing checklist with radar chart, action items for low-scoring areas, and print-ready export.

Size a pull-system replenishment loop from daily demand, lead time, container quantity, and safety factor. Shows cards, max WIP, and days of supply.

Estimate setup reduction impact from current and target stopped time. Calculates time saved, capacity gained, and annual value.

Calculate Every Part Every Interval for mixed-model production. Estimate run time, setup capacity, and lot quantities by part family.
