Lean is rapidly gaining ground in Denmark. Three out of five industrial enterprises have introduced lean techniques, and the lean wave is now reaching other areas such as finance, health, construction and education sectors as well as the entire public sector. The first pioneer enterprises in the administration and service sector are well on their way to reaping the benefits of working with lean. These enterprises have shown that using lean as a management tool can bring down case processing times, improve customer service, reduce employee stress and increase efficiency – using fewer resources. Lean is about streamlining the areas of an organization or company that create customer value and eliminating everything without value for the customer. The entire organization takes part in this process which aims at creating a corporate culture that spurs everyone to do even better all the time. LEAN MANAGEMENT in the administration and service sector offers an introduction to working with lean, suggesting ways in which leaders can reflect on their organization and explaining how to handle the process of introducing lean techniques.
