This panel will discuss the prominent trend of business consolidations in the enterprise software industry and proffer best practice management techniques for user experience teams following a successfully achieved merger or acquisition. Our panelists are UX managers who have experienced multiple mergers or acquisitions and will represent both the acquiring and acquired companies' perspectives. This panel builds on the success of a SIG organized at CH 2010. It will focus in on the UX management aspect post M&A, since this was most interesting to our audience. We will discuss design and technical challenges such as multiple UI technologies and platforms, navigation paradigms and menu structures, interaction behaviors, visual designs, as well as cultural and organizational challenges such as different maturity levels of UX teams, User Centered Design practices, job titles, talent management, geographical distribution and other cultural differences. Our goal is to explore best practice solutions that could help other UX managers facing similar challenges.
