Diploma Thesis from the year 2006 in the subject Business economics - Business Management, Corporate Governance, grade: 1,0, Euro-Business-College Jena, language: English, abstract: Some things are as they are and they have worked well all the time. People are used to them. Sometimes they know, that things could work better, sometimes they don't. One important thing in small and medium sized enterprises is communication and the flow of information. This sometimes can be crucial to the surviving of such firms. Although, some organisations know that they have a deficit in the communication or information process, they are not able to initiate any change. This diploma has the aim to point out this critical issue and to show how practices of communication and data flow can be improved. Firstly, the author gives an overview about theoretical approaches and than she will analyse the dataflow for a commercial organisation of the middle class. Here, it is important to say, that the measurement of the effects of such an optimisation is hard to realise, as effects can't be measured on numerical or monetary scale. The main concern of this diploma is not the theoretical explanation of types of data banks or the programming of such a data bank, which common literature describes. It is rather the establishing of more efficient methods to deal with the daily business and at least not to loose the basis of business, namely, the delivering of value to customers. Therefore, this diploma will present a probably total different perspective of this theme in practice, because of the individual tailoring, adaptation and transformation of theory to a practical solution.
