It is of vital importance never to forget that the world is ever changing. Therefore, it is crucial for organizations not to only alter but also to improve their performance in order to become more competitive on the market. One way of achieving this is to work with continuous improvements. However, this requires that the employees receive the needed training for this purpose. In multinational corporations they must also all receive the same training in order to create a common culture throughout the whole organization. This study therefore aims to investigate how a multinational corporation can organize an Improvement Management Training. Which are the main areas that are desirable to have knowledge in when leading an improvement work? In order to identify the areas of interest, a case study has been performed at Ericsson Supply Site Borås. The investigation was conducted as a combination of a qualitative and a semiquantitative study in order to determinate the empirical data. The results revealed that the following five major areas are essential for an Improvement Management Training: Leadership, Lean¸ Organizational Behavior, Project Management and Strategic Management.
