Until I started working with M&A integration, I did not fully understand the importance of culture in good business. I now completely understand just how important culture is because I have seen a lack of merged culture tear apart a few integration efforts. In the end, everything comes down to the fact that integrations are the joining of groups of people. Whether you are trying to integrate finance functions, HR functions, or any other function, the joining together of people to make this integration is what delivers results. If people do not merge to see that they share a culture and are working together to mutually benefit I that shared culture, they will not work to make it happen.
