How do you identify and eliminate the seven wastes of lean production in your processes?

由人工智能和领英社区提供技术支持

Lean production is a philosophy and a methodology that aims to maximize customer value and minimize waste in any process. By applying lean principles to production engineering, you can improve the quality, efficiency, and profitability of your products and services. In this article, we will show you how to identify and eliminate the seven wastes of lean production in your processes, using practical examples and tools.

1 Waste 1: Overproduction

Overproduction is the most common and costly waste in production engineering. It occurs when you produce more than what the customer needs or wants, or when you produce it too early or too fast. Overproduction leads to excess inventory, storage costs, defects, obsolescence, and reduced flexibility. To eliminate overproduction, you need to align your production with the customer demand, using techniques such as pull systems, kanban, just-in-time, and batch size reduction.

- On time of start in production engineering, overproduction is common. In my experience, it often results from a lack of alignment between production and customer demand. One thing I've found helpful is implementing pull systems like Kanban, which prevent excess inventory buildup by signaling when to start and stop production based on actual demand.

The use of tools such as Kanban cards helps to visualize workflow and control work-in-process, while just-in-time manufacturing closely aligns production schedules with market demand, reducing lead times and increasing responsiveness.

2 Waste 2: Waiting

Waiting is the waste of time and resources that occurs when one process or activity is idle or delayed because of another. Waiting can result from poor planning, scheduling, coordination, communication, or equipment breakdowns. Waiting reduces the throughput, productivity, and responsiveness of your production system. To eliminate waiting, you need to optimize your process flow, eliminate bottlenecks, balance workloads, synchronize activities, and implement preventive maintenance.

3 Waste 3: Transportation

Transportation is the waste of moving materials, parts, or products from one place to another without adding value. Transportation can cause damage, loss, deterioration, or contamination of your inputs or outputs. It can also increase the cycle time, labor costs, and energy consumption of your production process. To eliminate transportation, you need to minimize the distance and frequency of movements, using techniques such as layout optimization, cellular manufacturing, point-of-use storage, and standardization.

4 Waste 4: Overprocessing

Overprocessing is the waste of doing more work than necessary or adding more features than required by the customer. Overprocessing can result from poor design, specifications, or standards, or from using inappropriate or outdated technology or equipment. Overprocessing increases the complexity, cost, and risk of errors or defects in your production process. To eliminate overprocessing, you need to simplify your operations, eliminate redundancies, follow customer requirements, and adopt lean design principles.

5 Waste 5: Inventory

Inventory is the waste of storing excess materials, parts, or products that are not being used or sold. Inventory can result from overproduction, inaccurate forecasting, long lead times, or poor quality control. Inventory ties up capital, space, and resources, and exposes you to the risk of spoilage, obsolescence, or theft. To eliminate inventory, you need to reduce your inventory levels, using techniques such as pull systems, kanban, just-in-time, and cycle counting.

Através da gest?o de estoque, fizemos um trabalho em parceria com o fornecedor trabalhando com embalagens consignadas. Monitorando as reposi??es, conseguimos priorizar tarefas, otimizar a produtividade e reduzir custos (impacto em fluxo de caixa)

6 Waste 6: Motion

Motion is the waste of unnecessary or excessive movements of people or equipment within your production process. Motion can result from poor layout, ergonomics, or organization, or from using inefficient or inappropriate tools or methods. Motion wastes time, energy, and effort, and can cause fatigue, injury, or accidents. To eliminate motion, you need to improve your workplace organization, using techniques such as 5S, visual management, poka-yoke, and kaizen.

7 Waste 7: Defects

Defects are the waste of producing products or services that do not meet the customer expectations or specifications. Defects can result from human errors, machine errors, process variations, or poor quality control. Defects cause rework, scrap, warranty claims, customer dissatisfaction, and reputation damage. To eliminate defects, you need to improve your quality performance, using techniques such as quality at the source, statistical process control, root cause analysis, and six sigma.
