In an increasingly competitive global market, mergers and acquisitions are a popular strategy for continuous external growth, yet only 40% of such initiatives achieve their ROI targets. That’s because the process of merging two companies—involving significant operational and cultural changes—is a complex challenge for management teams who often have limited experience in the field. We find that the major issues revolve around:

  • Integration strategy and merger process steering
  • Technology integration
  • Change management
