Lean production: (1) eliminate all waste, reduce cost, (2) shorten process cycle and enhance reaction ability.

Six Sigma: (1) eliminating variables and increasing value; (2) Optimize the process and improve the quality.

Second, the focus of attention.

Lean production: value flow, problems, tools and methods, 5S field management, just-in-time production, rapid mold changing, kanban, basic IE, concurrent engineering, visual management, automation, leveling, TPM, constraint theory, continuous improvement, manufacturability/assemblability-oriented design, value engineering and standardization.

Six Sigma: Analytic Hierarchy Process, Scatter Diagram, pareto chart, Causality Diagram, Correlation Diagram, System Diagram, Affinity Diagram, Matrix Diagram, Short Array Data Analysis Method, Process Decision Procedure Diagram, SIPOC Diagram, QFD, FMEA, DOE, SPC, Measurement System Analysis, Variance Analysis, Balanced Scorecard.

Third, * * * similarities.

(1) Focus on customer satisfaction, customer-driven, (2) Focus on financial results, (3) Focus on continuous overall system improvement, (4) Focus on changing concepts and behaviors (Note: Lean requires changing the concepts of "department" and "queuing in batches" into the concepts of "team" and "continuous flow", and (5) Full participation.

Fourth, characteristics

Lean production: (1) The tool is soft but effective; (2) Emphasis on flexibility and agility; (3) Emphasize throttling.

Six Sigma: (1) excellent tools and powerful functions, (2) emphasis on systematization and standardization, and (3) emphasis on open source.

Verb (short for verb) working method

Lean Production: Top-down Promotion and Off-line Control

Six sigma: top-down propulsion, combination of off-line and on-line control

Sixth, the main effect

Lean production: (1) Reduce all waste (including inventory, defects, etc. ), (2) optimize the process, shorten the delivery time, (3) improve productivity, (4) reduce costs and increase capital investment.

Six Sigma: (1) reduce variation, unify output, (2) eliminate defects, improve quality, (3) increase customer value and profit, (4) customer satisfaction and loyalty.

Seven. superiority

Lean production: (1) continuous comprehensive innovation and change, (2) emphasis on continuous flow and pull, (3) comprehensive cooperation with relevant stakeholders, (4) overall optimization, pursuit of perfection, and (5) quick results.

Six Sigma: (1) apply a large number of statistical tools to accurately define the problem, (2) comprehensively improve and design the process, and (3) pursue perfection and Excellence (continuous improvement).

Eight. insufficient

Lean production: (1) relies too much on empirical management and lacks quantitative analysis; (2) The fluctuation is not handled well, so it is difficult to be "lean"; (3) Lack of personnel training and integration of systematic methods; (4) Lack of quick success and instant benefit leads to "non-lean" rebound.

Six Sigma: (1) can't improve the process turnover speed, (2) does not encourage innovation and change.

There are many consulting companies in Shenzhen, but few consulting companies do lean production management training. I suggest you pay attention to Shenzhen Huatianmou enterprise management consultants, who are the top 50 lean production management consultants in China.
