A career in lean manufacturing
Lean principles have been critical in increasing efficiency across organizations via cost reduction, reducing wastage, and relying on customers’ demands to drive the processes. Although the lean principles started in the manufacturing industry in the 1950s, today they are applicable in different kinds of enterprises and have varied applications.
Despite its roots in the manufacturing industry, lean can work in any organization with a process-driven environment. The primary objective of lean is to detect and modify or remove any part of the process if it is not value-adding. In doing so, lean can improve the response speed to customer demands and ensure better-quality production at lower costs.
Who needs lean manufacturing?
Any company that is in need of lean manufacturing is quite easy to identify. It displays operational deficiencies in any of the following:
- Excess buffer stock inventory
- Poor flow of information
- Production goals and schedules are rarely fulfilled
- Excess overhead costs
- Unnecessarily long cycle times
- Complex operating procedures
- Excess of some inventory, while being short on others
- Shipping containers are empty or products are damaged during shipping
- Long lead times
- Customer service is poor, and clients are unhappy
- Errors in the documentation for inventory, product specification or shipping
These are some of the usual symptoms of companies that are in dire need of lean manufacturing strategies.
Implementing lean processes
Any implementation of lean manufacturing must be supported by the top management as it may require a change in multiple processes. Before execution of a change at a broad scale, it is best to showcase a test implementation on one product.
To implement lean manufacturing, the company will require an individual who will spearhead the lean program. This individual will also engage in planning and educating employees about the changes and new systems. In addition, the person will have to design the new processes, set quantifiable goals, and set up a time scale for implementation of the lean system in the test case. While working out the test case, it is also important to take into account the customer requirements as they can change from time to time.
Once the test case is successfully demonstrated, the company can implement the same practice for all the products.
After the implementation of the lean manufacturing process, its success can only be measured by well-rounded metrics. If insufficient metrics are used, some of the information may be lost. For example, focusing only on production labor efficiency can lead to failure in identifying other performance issues and client satisfaction.
If the implementation is successful, employees will also be able to identify the changes and benefit from working in a lean facility. In a lean organization, workflow processes will be smoother with no information delay, reorganization and removal of unnecessary steps, balancing of schedules, and no time wastage, resulting in increased productivity.
Optimizing lean manufacturing processes will also have an impact on the supply chain. With a lean supply chain, the company will have a lower dependency on forecasting, better chances of accommodating customers’ varying purchase orders, improved relationships with suppliers, and an overall lower wastage.
Although the implementation of lean manufacturing will require capital expenditure, most of the changes can be implemented with existing machines and tools. Investing in going lean works best if the company is oriented to increase revenues, market share, competition and profits. As customer satisfaction is what makes money in a company, going lean will certainly have a financial impact.
What are the benefits of lean manufacturing?
In simple words, lean manufacturing can improve productivity and reduce any wastage. Quality reliance and quick delivery of goods from manufacturers is the new normal when it comes to customers’ expectations. Manufacturers can either meet the requirements by shortening their cycle time or lose the business. Customers can simply change their supplier if they find one that can meet their expectations. To maintain the competitive edge, maintain optimal operations and satisfy customer expectations, manufacturers incorporate the lean systems operation strategy.
Ultimately, the advantages of lean manufacturing depend on the business goals and expectations. Some of the common benefits of lean manufacturing are:
Saves time: One of the main components of lean manufacturing is improving efficiency and reducing cycle time. Any company that implements it can save time in workplace processes, resulting in better output.
Saves money: Reducing the wastage of resources can help companies save money. For example, if the number of defective parts produced decreases, it can reduce the cost of materials required.
Employee motivation: Continuous improvement, adaptability and learning are some of the most important factors of lean manufacturing. Employees can feel motivated if they can contribute to the company by learning from mistakes and solving them using critical thinking.
Environment protection: Minimizing waste will also help in protecting the environment in the long run. For example, less shipping of supplies will be required if the processes are lean, thereby lessening the impact on the environment by saving gas and reducing pollution.
To implement lean strategies successfully, firms will need competent staff and employees familiar with lean manufacturing. A lean manufacturing master’s can help in starting the lean journey in your company or help accelerate your growth in the industry.
Examples of organizations employing lean manufacturing
Toyota was the first company to adopt the principles of lean manufacturing. The company named it the Toyota Production System. This system eliminated waste and allowed the company to master the ability to lower production or discontinue products that were not meeting customer requirements. In addition, several tasks in Toyota are automated, which reduces the human effort and chances of faults. The ‘Just-in-Time’ concept ensures that the process only manufactures what is required for the next step in a continuous flow. This way, there are no extras and productivity is improved.
Nike is another famous company that has adopted lean manufacturing practices. The updating of its processes led to less wastage, higher customer value, and some interesting unforeseen benefits. Lean manufacturing in Nike resulted in reduced poor labor practices in overseas plants by 15%. The lean system, as designed, focused on valuing the worker more than the earlier business practices, as most of its manufacturing plants were overseas. Improving employee value resulted in a higher value to the company as a whole.
Harley-Davidson also adopted lean manufacturing principles to streamline its operations and empower its employees. This led to a continuous improvement in its operations, and the company named its strategy the Continuous Improvement System. This strategy is based on the nine lean tools, which include the usual 5S, total productive maintenance and standard work. The company also focused on improving its employees’ skills as well as training them in the requirements for a lean system. It believes in empowering employees so that they can continuously improve their work and add more value for the customers.
