The purpose of this Master Thesis is to evaluate the possible influence of religion and its underlying beliefs on the management of a corporation. Various aspects such as business objectives, strategic management tools like the value chain and the five forces analysis, human resources management and different business etiquettes will be taken under consideration. The analysis will be conducted with the inclusion of the world religions Christianity and Islam. Since Max Weber studied the coherence of religion and economics many years before during which differences between Catholics and Protestants have been examined, this Master Thesis will also differ between those two confessions in order to find out more outcomes in view of the different exercise of religion. Religion takes in an important role in economics due to globalization. People from different cultures work together and get in business contact more easily than a few years ago. To avoid misunderstandings and issues with employees, customers or partners managers should have basic understandings of the underlying values and beliefs that shape religions and cultures. Considering, for example, the Ten Commandments of Christianity, a religious influence in the daily life of a company can easily be constructed. That Sunday is the day off and people do not work on that day of the week can be attributed to this religion and the commandment “Remember the sabbath day”. A fair and corruptionfree partnership might be affiliated to the commandment “You shall not steal”. “You shall not bear false witness against your neighbor” should be as important in business life as in private relationships. The analysis of religious contents in management will be conducted based on literature, the scriptures of Christianity and Islam and expert interviews. A recurring difficulty is the relation and segregation of religion and culture.
