The purchasing function has become a strategic position for most companies. Activity in an organization cannot be performed without the presence of the information, which means that communication is important for being able to perform a task or activity. Communication related to the purchasing process has been investigated at Gavlegårdarna, a real estate company located in Gävle. In this work, Gavlegårdarna wanted to examine whether there is an opportunity to improve communication and investigate factors that lead to a lack of communication. The purpose of this study was to get a general image and increase understanding of factors that affect communication. The study is based on a case study, where one interview took place in the purchasing department and a questionnaire sent out to people who work daily with purchasing function.
