In our work we want to concentrate on the management of explicit knowledge, which can be formulated and stored in an IS. One reason for this is that it comes closer to the notion of information and vice versa. Therefore knowledge can be defined “as a justified belief that increases an entity’s capacity for effective action.” (Nonaka 1994). We use a special perspective different to the classical one as we assume for our explanatory approach that “knowledge is an object to be stored and manipulated [and retrieved]” (McQueen 1998; Zack 1999). Knowledge is therefore produced by persons and can be stored in respective IS. In addition, information is defined as “data in a contextual environment which helps give shape, and make sense of the raw numbers and text” (McQueen 1998). Similar to our view of knowledge information is represented by objects and can therefore also be operated in and via IS. Therefore it is not so much important in our approach whether we talk about knowledge or information. For us, it is important what makes either knowledge or information not available or not available in expected quality (Wang and Strong 1996) to users in the way they can and are willing to use it.
