Study Notes
Lean Principles and the McDonald Brothers
- Richard and Maurice McDonald revolutionized the fast-food industry by changing the traditional service process.
- Introduced lean processes led to faster service, reducing lead time and operational costs.
- The old process involved multiple steps by a waiter, while the new process allowed customers to order directly, streamlining operations.
Process and Lead Time in Lean
- A process consists of linked activities directed toward achieving a goal.
- Lead time refers to the total time taken from order placement to delivery; shorter lead times enhance customer satisfaction and reduce costs.
- Examples of processes include cleaning storage, assembling cars, and responding to customer inquiries via email.
Waste in Lean
- Lean focuses on eliminating waste (muda) to reduce lead time.
- Waste is defined as non-value adding activity, whereas value adding activity (VAA) includes tasks that transform products and that customers are willing to pay for.
- Essential Non Value Adding Activities (ENVA) are necessary but do not add direct value, such as regulatory paperwork.
Lean vs. Six Sigma
- Lean targets faster and cheaper delivery by minimizing non-value adding activities.
- Six Sigma, originating from Motorola in the USA in the 1980s, aims to reduce process deviation to improve quality.
- Both methodologies can be applied across different sectors, not just manufacturing.
Poka Yoke and Inspections
- Poka Yoke is a mistake-proofing technique that seeks to reduce defects, minimizing the need for inspections.
- While some inspections are legally required, Lean criticizes unnecessary inspections that could be avoided through improved processes.
Overproduction and Pull Production
- Overproduction occurs when large quantities are produced regardless of current demand, leading to excess inventory and potential financial strain.
- Pull production emphasizes manufacturing based on actual customer demand, allowing for smaller inventories and quicker problem resolution.
- Just-In-Time (JIT) manufacturing aligns inventory closely with production schedules, reducing waste and improving efficiency.
Implementing JIT
- Transitioning to JIT should be gradual, adhering to the kaizen principle to ensure operational stability and effectiveness.
- Advisors recommend spreading JIT implementation over at least three months to lower inventory levels carefully.
