Inhaltsangabe:Abstract: Near the beginning in Homer?s Odyssey, the son of Odysseus, young Telemachus, had been advised by the goddess of wisdom, Athena, to ask old King Nestor about an important issue, relating to the residence of his father. Telemachus hesitated, explaining his doubts by introversion and insecurity. Telemachus? behaviour lives on in the contemporary context of Mergers &Acquisitions where still the most inexperienced, unskilled professionals supposed and expected to know everything long before the process starts. ?Developing rules and principles for preparing and implementing acquisition projects? attempts to provide a general idea about one of the most difficult, vast, complicated, and sometimes immeasurable growth strategies in management, M&A. While M&A activity had been an Anglo-American occurrence during the first merger wave, the process of concentration had changed to a global phenomenon. Financially driven acquisitions and corporate raiders had been popular during the 1980s, the 1990s and the present is faced with strategic M&A.

As a result, point four (Valuation techniques and financing methods) is only explained incredibly superficial. The final part of the present research - Part three - combines all the various aspects that had been evaluated during the study by providing some guiding principles for M&A success. Furthermore, the terms ?Mergers? and ?Acquisitions? are used interchangeably in the text because in many instances it is not clear whether one or the other is occurring. However, for certain purposes, it is necessary to distinguish the [¿]
