O giro de estoque emerge como uma métrica vital, refletindo a eficiência na gestão de inventário ao longo de um período específico. A frequência com que o estoque é vendido ou utilizado é fundamental para compreender a eficácia na conversão desse recurso em vendas ou produtos finais. A elevação do giro de estoque não apenas reduz os custos associados à retenção de estoque, mas também melhora o fluxo de caixa, evitando obsolescência e deterioração. A fórmula que relaciona o custo das mercadorias vendidas ao valor médio do estoque permite uma avaliação precisa. A comparação do giro de estoque com metas, dados históricos ou benchmarks setoriais fornece insights valiosos para otimizar a gestão de estoque e manter a competitividade no mercado.

Inventory management plays a crucial role by -Reducing Waste: Maintaining optimal inventory levels minimizes excess and obsolete stock, aligning with lean principles to eliminate waste. -Enhancing Responsiveness: Keeping the right amount of inventory facilitates quick response to customer demands, aligning with the lean concept of customer focus. -Preventing Overproduction: Controlling inventory helps prevent excessive production, reducing the risk of producing goods that may not be immediately needed. -Minimizing Lead Times: Well-managed inventory contributes to shorter lead times, promoting agility and responsiveness to market changes.

#2 Here are more applications of Little's Law: * Calculate the queue length at any station. First calculate the TH (UPH of the station). Then measure its CT. Plug the two numbers into WIP = TH * CT, and you can determine how many units are queued inside that machine. * Calculate your product's inventory time. You might want to know this if you have items with shelf life, such as a discharging battery. Measure your storage facility's actual usage capacity, WIP. Using a stop watch, measure the rate at which units are put into and taken out of the facility, TH. Plug the two numbers into CT = WIP/TH, and that is your inventory turnover time at the facility.

O giro de estoque é a frequência com que os produtos são vendidos ou renovados em um período. Um alto giro é bom, pois indica vendas rápidas, reduzindo custos de armazenamento. Porém, um giro excessivamente alto pode gerar problemas de falta de estoque. Equilibrar o giro é essencial para ajustar compras, maximizar lucros e satisfazer clientes. É crucial monitorar regularmente para tomar decisões estratégicas eficazes.

Lean manufacturing effectiveness with Inventory Turnover is gauged by tracking how quickly inventory is used and replenished. Calculate Inventory Turnover ratio by dividing the cost of goods sold (COGS) by the average inventory. Higher turnover indicates efficient use of resources, reduced holding costs, and improved responsiveness to demand. Regularly monitoring and optimizing Inventory Turnover aligns with lean principles, emphasizing minimal waste and efficient production flow. Continuous improvement, accurate demand forecasting, and streamlined processes contribute to enhancing Inventory Turnover in a lean manufacturing context.

When tracking yield, it is important to maintain an yield bridge. An yield bridge tracks the failure rate (FR) and failure mode at all test or inspection stations, including stations which both assemble and test. The yield bridge aids you in determining the criticality of each issue, so that your team can prioritize which issues to chase. During new product introduction stages, the most critical issue is not necessarily the failure mode with the highest FR. For example, the line may catch a 0.1% walking wounded issue which results in a catastrophic reliability failure in the future, like an improperly formed wireform inside a MEMs device. Even though the FPY is high, at 1000DPPM this is an unacceptable failure.

O rendimento de primeira passagem surge como uma métrica crucial na avaliação do controle de qualidade, representando a porcentagem de unidades que atendem aos padrões sem retrabalho, sucata ou defeitos. A eficácia nessa medida não apenas reduz o desperdício, economiza tempo e materiais, mas também eleva a satisfação do cliente ao garantir a entrega de produtos livres de falhas. A fórmula que compara as unidades aprovadas na inspeção de qualidade com o total produzido fornece uma visão clara do desempenho. A comparação do rendimento de primeira passagem com metas, dados históricos ou benchmarks do setor é fundamental para impulsionar melhorias contínuas na qualidade e eficiência do processo de produção.

First pass yield (FPY) is a vital metric in lean manufacturing, indicating the percentage of units meeting quality standards without rework or defects. It reflects the effectiveness of quality control and error prevention. Improving FPY reduces waste, saves resources, and boosts customer satisfaction. For instance, in an electronics assembly line, a high FPY would mean most circuit boards are assembled correctly the first time, reducing waste and increasing efficiency.

First Pass Yield (FPY) in manufacturing is a critical metric indicating the proportion of defect-free products produced without rework or corrections during the initial manufacturing attempt. It gauges process efficiency, quality control, and waste reduction. A high FPY signifies streamlined processes, minimizing resource utilization for rework. Monitoring and improving FPY align with lean manufacturing principles, focusing on right-first-time production. This metric is vital for enhancing overall product quality, customer satisfaction, and operational effectiveness. Continuous FPY evaluation supports a culture of ongoing improvement, crucial in maintaining competitiveness in the manufacturing landscape

Every employee at a company has their own goal for bettering their own lives. The company's management must align both the company's goal and its people in order to achieve proactive results. Counselling and education for both physical and mental health can be provided. Companies can organise icebreaker events to help employees feel more empowered. Innovative ideas might be encouraged by providing a bonus or a company stake. Based on the shared vision, businesses can invest in training employees in current trends such as AI, data science, and so on, which can be used to improve quality and productivity.

Single most important thing for effective lean manufacturing practice at work. WPO (work place organisation) is a daily basis routine activity which is key to lean implementation, however being a routine work, employees tend to get bored easily and starts skipping, avoiding maintenence of systems and practices. It important to keep them engaged and motivated to adhere to the systems and processes.

Para impulsionar o engajamento dos funcionários: 1- Comunique-se abertamente e promova um ambiente positivo. 2- Ofereça oportunidades de crescimento e reconhecimento. 3- Equilibre a vida pessoal e profissional. 4- Envolva os funcionários nas decisões. 5- Mostre como o trabalho deles se alinha aos objetivos da empresa.

Quando a empresa apresenta um bom nível de engajamento dos colaboradores, seus processos tendem a ser mais produtivos. Além disso, a qualidade das entregas é superior, o que impacta na competitividade e produtividade da empresa. Funcionários bem engajados, que se comprometem com suas tarefas e com a entrega de resultados de alto nível, tornam-se um diferencial para a empresa em um mercado cada vez mais competitivo.

Employee engagement is best way to increase the effectiveness of lean manufacturing,if employee is highly motivated then it's performance converted into productivity rejection reduction,follow the best possible system for zero Defect quality product.

Lean Manufacturing is all about value addition and waste reduction which is a continuous improvement process. Briefly, it is all about the adaptable and applicable systems and robust processes (which ever or what ever; and these vary with new developments and idea generations) which helps the companies to provide a faster and efficient products & services and ultimately creating or adding value to both the companies and customers.

Artisan are also measured on the cost of new parts fitted vs old parts repaired. Older generation can refurbish parts and new generation has become new part fitters.

The effectiveness of lean manufacturing can be measured through key performance indicators (KPIs) such as cycle time reduction, inventory turnover, defect rates, lead time, and overall production efficiency. Regularly monitoring these metrics helps assess the impact of lean practices on operational performance and identify areas for continuous improvement.

Lean is Resource intensive wasteful garbage policy. Throwing 20k in tooling away because you haven’t used it in 6 months is a ridiculously wasteful concept and I cannot support that. Literally worked for people who were ok with doing this.

Well, never throw it away, create an area away from your immediate production area, tag and catalog it electronically as time permits. Tag it out later if that job comes back or you can repurpose. The point is to organize your work area removing clutter and standardizing as much as possible across the shop. Makes training easier and reducing waste like hunting and gathering. The system can be designed around what you need it to be in being more efficient with spindle up time.
