"The Speed of Human and Task Integration in Mergers and Acquisitions" by Carolin Proft offers a comprehensive analysis of integration in M&A processes. The book highlights the crucial role of integration speed and its impact on the success of mergers and acquisitions. Proft develops a research model that considers the speeds of task and human integration as independent variables influencing M&A performance. By evaluating data from 101 German-speaking companies, the author demonstrates that the speed of task integration negatively affects M&A performance, while the speed of human integration promotes M&A success. This study is unique as it quantitatively proves that both types of integration occur at different speed levels. Consequently, the chronology of these integration types has a significant impact on M&A success.
