iProspect is a global digital marketing agency and work primarily with search marketing. They were the first search engine marketing agency in the world when the company started up 1996 in Boston, Massachusetts, and the first in Sweden to offer services in search marketing after establishing themselves on the Swedish market the following year. iProspect can be found in the södermalm office in south central Stockholm. They are a comprehensive agency within search and offer everything from search engine optimization and sponsored links to advertising on social media. They’re goal is to lead developments in search marketing and to keep ahead of competition. To do this they must constantly challenge themselves. The market is constantly evolving and new services are offered regularly. This report describes the development of a design document for a mobile application for increased knowledge and for sharing knowledge about a new service from iProspect . The service in question, attribution, is already sold today by iProspect in markets abroad and the ambition is to do so also in Sweden as soon as there are resources in the form of "know-how". The draft design document should evolve to include their employees with increased knowledge of how attribution can be applied as a service. During the execution of this work, interviews, usability tests with prototypes and observations were made and conducted. Based on the methodology and the work process, the results have been analyzed and discussed. Hopefully the application will be of use prior the implementation process of the new service.
