Production calculators

Enter your figures to get a quick result. Use consistent units.

Takt time calculator

Takt time = net available production time ÷ customer demand.

Result3.50 minutes per unitAvailable net time: 420 minutes.

OEE calculator

OEE = Availability × Performance × Quality. Enter each percentage from 0 to 100.

Result83.8% OEEBased on the values entered above.

OEE benchmarks depend on equipment, process, and operating conditions; use your site's target and baseline for context.

5S workplace audit

Check each item that is currently in place in the work area.

Audit score: 0 of 10 items (0%)

This checklist is a starter template. Adapt it to your site's safety, quality, and operating standards.

Waste walk checklist

Observe the process, describe what you see, and record the impact.

No observations added yet.

Kaizen idea tracker

Start small: define the problem, test a countermeasure, and check the result.

No ideas added yet. Entries stay in this page while it is open; download a CSV to keep a copy.

Value stream mapping: quick start

See the whole flow before optimizing individual steps.

1. Choose a product family

Follow one representative product or service through the process from request to delivery.

2. Walk the actual process

Capture process steps, cycle time, changeover time, uptime, WIP, and information flow at the workplace.

3. Identify the gap

Compare lead time and processing time. Mark queues, rework loops, bottlenecks, and unclear handoffs.

4. Design a future state

Set a clear improvement goal and consider flow, pull, smaller batches, and reliable standard work.

5. Build an action plan

Assign owners, due dates, and measurable outcomes for each improvement experiment.

6. Review and learn

Check results at the gemba, update the map, and make successful changes part of standard work.

Lean tools support structured problem-solving; always follow your organization's safety, quality, and regulatory requirements.
