In addition to computers, smartphones, laptops and tablets are increasingly integrated into everyday work in the office. They are both media and tools that shape the communicative work activities of the companies. Socio-cultural changes in turn generate new media. The concept of mediatization describes these changes, which are subject to constant change. This article is an excerpt from my dissertation, where I am researching the design of mediatized office work. I asked managers about their corporate culture, their working media and their communicative way of working. In order to classify different design aspects of companies, I use Rogers' "adopter"-types, in which different degrees of mediatization can be seen.
