Christina LeimerExternal pressures on higher education are pushing it toward systemic changes that increasingly necessitate collaboration. Federal grants that call for interdisciplinary research, public-private partnerships, assessment, accreditation expectations for a culture of evidence and continuous improvement, and budget deficits all require individuals and organizations to collaborate, yet traditional higher education structures do not foster this style of working (Alfred and Rosevear, 2000;Kezar, 2005;Duke, 2002;Keeling, Underhile, and Wall, 2007). Many describe the organization of colleges and universities as loosely connected vertical structures. Discipline-based academic departments, bureaucratic and hierarchical administrative units, segmented business operations, functional divisions such as academic affairs and student affairs, foundations, athletics programs, and unions operate in parallel with one another, all pursuing their own goals with varying degrees of awareness or support of larger organizational goals and issues. This vertical structuring results in loosely connected silos that inhibit crossdisciplinary and cross-functional collaboration, narrow people's view of their role and its potential impact on the larger organization, and breed allegiance to their smaller organizational units over the institution as a whole. Without horizontal processes that bring people and functions together, institution-wide changes are extremely difficult to accomplish.
