The study is based on a data set which has been corrected by the service company and analyzed using Lean Thinking tools. It provides the application of Lean Service into the actual service company. The project is intended to provide a pragmatic view of Lean application. It indicates some of the key practical factors to watch for when considering implementation aspects at each stage of the journey. Both value identification and service quality improvement were applied. The paper explores and clarifies Lean by showing how the process can be supported to add incremental value. The paper demonstrates how Lean methods can be adapted into real-world situations by applying Lean tools to the actual company. So, companies of different service industries can also learn and adapt the Lean approach more effectively.
