Maintenance
- MTBF / MTTR / AvailabilityEnter operating hours, failures and repair hours. It returns the three indicators and an automatic reliability vs. maintainability diagnosis.Calculator
- 6:1 preventive / corrective ratioChecks whether your preventive intervals are short, long or well calibrated according to how many corrective jobs they generate.Calculator
- OEE calculatorAvailability × Performance × Quality and the shift minutes lost in each factor.Calculator
- Equipment criticality matrixFailure frequency times consequence: the list sorts itself into zones A, B and C.Interactive template
- Life cycle cost (LCC) comparisonTwo pieces of equipment compared by their total cost over their useful life: purchase, operation, maintenance and downtime.Calculator
- RPN calculator (FMEA)Severity × Occurrence × Detection (1 to 10 each) and risk priority at once.Calculator
Problem solving
- 5 WhysChain the 5 questions down to the root cause and note the corrective action. Your progress is saved in the browser.Interactive template
- Ishikawa builder (6M)Enter hypotheses in the 6 categories (Machine, Material, Method, Manpower, Measurement, Environment) for a specific problem.Interactive template
- SMART goal checkWrite your goal and tick which criteria (Specific, Measurable, Achievable, Relevant, Time-bound) it meets.Interactive template
- Pareto builder (80/20)Enter causes with their frequency or cost: it sorts them, calculates the cumulative % and marks the “vital few” that explain 80%.Calculator
- A3 report templateThe seven boxes of the A3 to solve a problem on one sheet. Your progress is saved in the browser.Interactive template
Time and processes
- Takt time calculatorAvailable time ÷ demand = the pace you need. It compares it with the measured cycle time of your process.Calculator
- Standard time calculatorObserved time, performance rating and allowances: normal time, standard time and pieces per hour.Calculator
- Cycles to timeDepending on the cycle time, how many repetitions to observe (General Electric guide).Calculator
- Rest allowance for effort calculatorEnergy expenditure of the job and the fraction of the shift that must go to recovery.Calculator
- Line balancing calculatorEnter tasks and times: theoretical minimum number of stations and balancing efficiency.Calculator
- Layout type selectorA few yes/no questions about your production and guidance on the type of plant layout.Interactive template
- Capacity and utilization calculatorBottleneck capacity against demand: whether the line can keep up and with what margin.Calculator
- Learning curve calculatorHow long each unit takes as the work is repeated, or what learning rate you have from two measurements.Calculator
Lean, quality and strategy
- Kanban card calculatorDemand, replenishment time and safety: how many cards are needed between two stations.Calculator
- Leveling (Heijunka) calculatorOrders for the period and production days: daily quantity and a repeating cycle with the mix interleaved.Calculator
- Sigma level (DPMO) calculatorDefects, units and opportunities per unit: DPMO, yield and sigma level with the 1.5 shift.Calculator
- SWOT matrix builderStrengths, weaknesses, opportunities and threats, with a strategy box for each cross.Interactive template
