Many companies must undergo organizational changes to achieve a more efficient business. This essay has focused on studying a small company, its development as well as its need for change. The company, Pärlans Konfektyr AB, is a manufacturing company located in Stockholm that has been operating since 2010. The company has in recent years, firmly increased its sales and is facing a number of changes as the company has grown.   The need for changes was mainly identified as technical, because of the need to implement a new business system. Understanding how a change takes place and how an organization can accomplish an implementation effectively is important as it requires a lot of time and resources. This has been investigated by studying theories and models for successful change and implementation work in previous research. The purpose of the study is to create an understanding of what kind of organizational changes a small company stands in front of and how these can be implemented in a successful way. The survey is a qualitative study and in order to be able to answer the study's research question, an interview survey has been applied, where the data has been analyzed and compared with previous research in the field. The conclusion of this study is that Pärlans Konfektyr AB is in a stage of ‘’growing pains’’ which leads to different challenges for companies that have strong growth in a short time. In combination with this growth, there is a need for new structures and routines in the business, for which several models from previous research can serve as auxiliary tools.
