Contemporary organizations often deal with a procurements process when purchasing system solutions from different suppliers. Many of these organizations either lack the knowledge, experience, or the time needed to successfully manage procurements processes. This research addresses the role of brokers in such processes, i.e., organizations mediating knowledge between customers and IT suppliers. A main concern for these brokers is managing knowledge flow across boundaries between different stakeholders. The management of knowledge is particularly challenging in requirements engineering processes involving different stakeholders who have distinctive understandings and perspectives of information system development. This thesis presents findings from a single case study in which a consulting firm providing broker services for eliciting and translating client's requirements in procurement processes of system solutions has been investigated. The empirical investigation was conducted through interviews with seven consultants from the firm North Consulting. It focused on formal processes, perceived key challenges, and applied problem solving methods. The contributions of the thesis lie primarily in three important findings: identification of competencies required to successfully broker knowledge in procurement processes, challenges in managing such processes, and, explication of methods, tools, and documents applied to overcome the challenges. / <p>The external partner has choosen to cooperate anonymously. / Den externa samarbetspartnern har valt att delta anonymt.</p>
