Lean Management FAQ
What is the major aim of lean management?
Lean management is the process of reducing work wastes in all business processes, techniques, and methods to help manufacturing organizations to reduce lead-time right from order stage to final sale of products to the customer.
Is there any difference from lean management and Toyota Production System (TPS)?
Toyota Production System was later given the name lean management by Womack in 1990. The purchase of TPS is the elimination of all wastes from business processes to reduce lead-time in production.
What is ‘Kaizen’ and what is its significance in lean management?
Kaizen in Japanese language means continuous improvement. In lean management, this Kaizen principle is applied in business processes as small incremental improvements at frequent intervals. In Kaizen application, all process improvements are attained without adding extra spaces or more employees or additional investments for the execution of changes.
Are the benefits of lean management tangible and measurable? If so, how long would it take to achieve results?
The results of lean management are tangible and measureable if applied properly on a weekly basis. Improvement in processes and increase in bottom line through reduction of wastes and costs are significant even in short-term. They are classified as hard savings and soft savings. Hard savings include reductions in inventories, cycle times, lead-times, and defects, with increase in productivity and achievement of zero defects performance. Soft savings consist of space saving and 99% improvement in on-time deliveries, apart from enhancement of employee attitudes and morale.
If lean management leads to employment of lesser people to achieve better results, then would it not lead to job cuts and disillusion among the employees?
The Kaizen principles do result in lesser number of employees but job cuts are not implemented by the management. Hence, managements executing lean management reduce headcounts on a long-term basis through reassignments, promotions, retirements, voluntary resignations, and non-renewal of contracts of temporary or part-time workers.
How could lean management be integrated with Six Sigma?
Lean management emphasizes on waste elimination from activities that do not have value additions, while Six Sigma focuses on reduction of variations or defects from processes. Hence, they are not contradictory and but complementary to each other. Integrating them is very easy.
