Data-driven planning or evidence-based decision making represents nothing new in its concept. For years, business leaders have claimed they have implemented planning informed by data that have been strategically and systematically gathered. Within higher education and student affairs, there may be less evidence of the actual practice of systematically and strategically gathering data to inform planning. Data-driven planning is often referred to in higher education as outcomes-based program review. The Western Association of Schools and Colleges (WASC) defines outcomes-based program review as a cyclical process for evaluating and continuously strengthening the quality and currency of programs. The evaluation is conducted through a combination of self-evaluation and peer evaluation by reviewers external to the program or department and, usually, external to the organization. The results of this process inform strategic planning. Adopting the practice of systematically and strategically gathering data to inform the development and implementation of a strategic plan will ensure its achievement. This chapter presents a combination of techniques for student affairs professionals to conduct data-driven planning.
