Find and remove waste

Start by seeing waste. It hides in transport, stock, motion, waiting, overproduction, over-processing and defects, and in unused talent. Map the current state, then remove the largest source first. Organize the workplace so that problems become visible.
Read the wastes guide

Speed up flow and changeovers

Flow is limited by the slowest step and by time lost to changeovers. Match the pace to demand with takt time, pull work with kanban and level the mix. Find the bottleneck, then cut changeovers and unplanned stops.
Read the SMED design guide

Cut defects and variation

Defects come from variation and from errors nobody can see. Use poka-yoke to make errors impossible, statistics to find and stabilize variation, and structured problem solving when something escapes. Verify root causes with data, because a five whys chain can stop at a symptom.
Read the SPC guide

Plan agile and smart production

Agile manufacturing adds the ability to change product and volume quickly. Automation pays off only after the process is stable, so standardize first. These pages cover agile cells, robotics, additive manufacturing and digital twins.

Work with people and workstations

Lean tools spread easily between companies, the behaviors that make them work do not. Improvement ideas come from the people who do the work, so make it safe to report problems. Good workstation ergonomics supports both safety and cycle time.

Lean rules that hold in practice

  1. Start with the value the customer pays for, then look for what blocks it. Do not start with tools.
  2. Map the current state before you improve it. Draw the value stream with times, inventories and defect rates. See वैल्यू स्ट्रीम मैपिंग.
  3. Improve the constraint first. Speeding up a step that is not the bottleneck only builds inventory.
  4. Standardize before you automate. Automating an unstable process makes the instability faster.
  5. Use visual management where flow is the problem and statistics where variation is the problem.
  6. Make errors impossible or visible at once with Poka-योक, and stop the line rather than pass a defect on.
  7. Cut changeovers before you cut batch sizes. Short setups are what make small batches affordable.
  8. Track a few figures, such as OEE, takt time and first-pass yield, and review them at the workplace. Keep the tracking simple, because a system that nobody updates becomes one more waste.
  9. Ask the people who do the work. Most improvement ideas come from operators, so make it safe to report problems.
  10. Check root causes with data. A chain of five whys can stop at a symptom, as the limits of the five whys explains.
  11. Sustain the gains with gemba walks and audits, or 5S and standard work decay.

Train for a belt

The three Lean Sigma courses follow the belt ladder. Yellow Belt teaches you to recognize waste and carry out tactical tasks under guidance. Green Belt prepares you to run improvement projects in your own department while keeping your regular job. Black Belt is for people who work Lean Six Sigma full time. Each course is free and has must-know checklists and a final exam.

Lean manufacturing questions, answered

Lean manufacturing is a system for delivering value to the customer with the least waste of time, material and effort. It comes from the Toyota Production System and rests on continuous improvement and respect for people. Start with the Toyota Production System guide.

Lean attacks waste and delay to speed up flow. Six Sigma attacks variation and defects with statistics, usually in DMAIC projects. They combine as Lean Six Sigma: lean removes steps that add no value, and Six Sigma stabilizes what remains. See सिक्स सिग्मा कार्यप्रणाली और DMAIC.

The seven classic wastes are transport, inventory, motion, waiting, overproduction, over-processing and defects. The eighth is unused human talent. 7+1 Wastes of Lean gives examples and countermeasures.

Takt time is the pace set by customer demand: available production time divided by demand. Cycle time is how long a step actually takes. When the cycle time of a step exceeds takt time, that step cannot keep up. See टैक्ट टाइम और साइकिल टाइम के बीच अंतर.

SMED, Single-Minute Exchange of Die, shortens changeovers by separating internal setup, done while the machine is stopped, from external setup, done while it runs, and then moving work from internal to external. It pays off where frequent changeovers force large batches. See SMED और SMED में आंतरिक बनाम बाहरी सेटअप.

Sort, set in order, shine, standardize and sustain, from the Japanese seiri, seiton, seiso, seiketsu and shitsuke. See The 5S Methodology.

Overall Equipment Effectiveness multiplies availability, performance and quality to show how much of the planned production time makes good parts at full speed. Compare a machine with its own history first, because benchmarks vary by process. See ओईई.

Pick one product family, draw the current-state value stream with times and inventories, and find the constraint. Improve that step first and measure the result. See वैल्यू स्ट्रीम मैपिंग और अड़चन विश्लेषण.
