What is lean manufacturing?Lean is defined as a set of management practices to improve efficiency and effectiveness by eliminating non-value adding activities and waste. Lean manufacturing is a methodology that focuses on minimizing waste within manufacturing systems while simultaneously maximizing productivity. This approach is based on the Toyota Production System. It was a practical solution developed by a medium-sized manufacturer to address its cash flow problems. Many manufacturers may be daunted by the size of automotive assembly plants and see them as a unique working environment that has little in common with their business. However, the reality is that the underlying principles of lean manufacturing can be applied in every manufacturing business, no matter how small. The truth is that the principles can be universally applied in other industries. A lot of companies use lean manufacturing principles to eliminate waste, optimize processes, cut costs, boost innovation, and reduce time. As a result, companies that implement lean manufacturing principles become more effective and competitive in the fast-paced, ever-changing global marketplace. What are the lean principles?A widely referenced book, Lean Thinking: Banish Waste and Create Wealth in Your Corporation, which was published in 1996, laid out five principles of lean: 1. ValueValue is created by the producer, but it is defined by the customer. Companies need to understand the value the customer places on their products and services, which, in turn, can help them determine how much money the customer is willing to pay. 2. The Value StreamThere are specific steps that need to be done in order to create a product or service from raw materials into a functional product through to disposal. Analyze the flow of product's entire lifecycle and examine if there is any step that is that does not add value and must be eliminated. Analyzing inefficiencies and taking steps to eliminate them is the first step toward becoming leaner. 3. FlowEliminate functional barriers and identify ways to improve lead time. This aids in ensuring the processes are smooth from the time an order is received through to delivery. Flow is critical to the elimination of waste. Lean manufacturing relies on preventing interruptions in the production process and enabling a harmonized and integrated set of processes in which activities move in a constant stream. 4. PullThis means you only start new work when there is demand for it. Lean manufacturing uses a pull system instead of a push system. Push systems are used in manufacturing resource planning (MRP) systems. With a push system, inventory needs are determined in advance, and the product is manufactured to meet that forecast. However, forecasts are typically inaccurate, which can result in swings between too much inventory and not enough. In contrast to MRP, lean manufacturing is based on a pull system in which nothing is bought or made until there is demand. 5. PerfectionLean manufacturing rests on the concept of continually striving for perfection, so that the number of steps and the amount of time needed to serve the customer continually falls. This entails targeting the root causes of quality issues and eliminating waste across the value stream. What is the purpose of lean manufacturing & why is it important?As the world speeds up and customers want more and more customization in shorter and shorter times, then the need to reduce time in every steps we take to deliver a product or service becomes even more important. Here are the main purpose of implementing lean manufacturing:

This means lower costs, lower working capital, better use of factory space, and greater flexibility and agility to respond to customer needs. What are the eight types of waste in lean manufacturing?Lean manufacturing defines waste as anything that doesn’t add value to the customer. This can be a process, activity, product, or service; anything that requires an investment of time, money, and talent that does not create value for the customer is waste. The eight lean manufacturing waste can be remembered using the acronym DOWNTIME:
Implementing lean manufacturing1. Have a Clear Strategic GoalLean is not a strategy nor an outcome. Lean is a method to deliver your business’ strategic goal. Start with a clear goal and communicate this to your team. Make them understand the importance of implementing lean manufacturing. You can start with the 4 purposes we discussed above. 2. Leadership “Walks the Talk”Just like in digital transformation process, leaders who aim to implement lean principles need to demonstrate lean leadership behaviors themselves. Remember as a leader “the standard you walk by is the standard you set” and this truism definitely applies to lean. 3. Map your Value StreamsWe have discussed how mapping the end to end flow of your production can help you identify loopholes. See whether there is any step you can improve or eliminate in your operations in order to reduce cost and shorten production time. 4. Set Clear StandardsProvide clear SOP for your employees and make sure they complies to the standard by conducting routine inspection. Having solid standard will stabilize your production process and help you deliver more consistent results, which in turn supports the lean principle continually striving for perfection. A digital inspection software like Nimbly can help you on this. 5. Develop Your Front-Line LeadersYour front-line leaders are the supervisors, team leaders and junior managers that your front-line staff directly report to. Front-line staff usually trust and listen to their immediate supervisor more than any other person in the business. Provide training for your front-line leaders on lean practices and let them lead their team to achieve the goal hand in hand. 6. Set Simple and Clear Measures that Can Be Improved Every DayIn order to know if your strategy is working and the lean principles are implemented successfully, you need to develop simple measures for safety, quality, and cost that can be measured every day. Make sure they can be easily understood and assessed by front line teams. Address issues that come up immediately rather than finding them has grown into significant problem in the monthly report. You can use an operational audit software like Nimbly to evaluate your manufacturing process. SummaryIdentify your production value stream through operational audit and eliminate any process that doesn't add value to the customer. This way, you can cut cost, reduce working capital, as well as bring greater flexibility and agility to respond to customer needs. Consult how your business can start implementing operational audit with the Nimbly team free of charge. Sources:
