Process Harmonization Phase Model in Post Merger Integration

Post merger integration (PMI) has received much attention in recent years due to an increasing number of merger and acquisitions (M&As). Process harmonization plays an important role during the PMI. The objective of this article is to define the milestones of process harmonization and develop a phase model. Nine approaches are illuminated and concluded to a process harmonization phase model. BPM implementation or optimization literature has been scanned for suitable approaches. Further expert interviews have been conducted and evaluated with qualitative content analysis. A combination of the different approaches is regarded as the optimum. This article provides two central results: First, process harmonization phases are divided into management system level and process level. Second, process harmonization phases exist of analysis phase, conception phase, realization phase and verification phase. A general overview of suitable methods for each phase is provided.
