Hi @rambansx — Good question. There are many reasons that this could be the case including differences in the perception or priorities for the outcomes, internal corporate politics, inexperience of the M&A teams in the development of integration plans, or even the perception that they did cover all basis at the time the integration plan was developed just to name a few. Remember too, regarding that last point, hind sight is always 2020. When you are in the thick of it, with so many moving parts, there is only so much you can plan for. Inevitably there will be unforeseen issues that come up, things you just cannot plan for that, when looking backward, we often are surprised there was not a plan for. In the end, the integration planning team must to the best they can with the information they have, guided by the transaction thesis and a strategic plan for the merged entity, and then still be flexible enough to adjust to the unknowable and unforeseen issues when they arise.
