註釋 Diploma Thesis from the year 2010 in the subject Business economics - Business Management, Corporate Governance, grade: 2.0, University of Applied Sciences Essen, language: English, abstract: On the one hand, it is often said that the manufacturing and service companies in the industrialised countries are well organised, the business processes are well managed, so the companies are able to work effectively and efficiently. On the other hand, a lot of companies, even big corporations, have gone bankrupt over the last years, because of their confusing and inefficient business process organisation, which also led the management to take wrong decisions. So how do these two statements match? Hence it has become more important for companies, especially for those which are globally organised, to focus on their business processes to either optimise or eliminate the one which adds no value. In this context it is an important approach to find out, in what way the most important methods of BPM, BPR, and Six Sigma can help organisations to face the challenges of today's turbulent marketplaces.
