    AC drive manufacturers promise product support for their products for decades. In AC drives there are components which are installed with software and providing product support includes being able to supply these components as spare parts. To ensure that these operations are efficient, we apply the lean principles to them. Because the range of product variants in this case is extremely vast, it is not reasonable to focus on improving the process of all products equally. The goal of this thesis is to find out, on which products the improvement efforts should be focused, how the lean principles can be applied to the process and what kind of effect applying lean principles to this process has. As a result, suggestions for the case company are given in order to improve their performance. The products are divided into four product groups that are prioritized according to their sales volumes. By using 80/20-principle, we decide to focus on two product groups which account for 77\% of total sales volume. In the order-to-delivery process customer values short delivery time and high product quality. During the process there are interruptions caused by insufficient order information. As there is no continuous improvement process in place for this process, these problems keep on recurring. We form a picture of perfection which describes the future state of the process. In this picture we ensure that high quality products are delivered to the customers with no interruptions in the process flow by applying poka-yoke to the software installation process, practicing 5S, implementing continuous improvement process to the order-to-delivery process and maintaining and improving standards.
