The Sloan Pillars have set the standard for university-wide online learning program assessment for more than a dozen years. In this paper, the authors propose the extension of the Pillars to corporate e-learning, offering an alternative to traditional enterprise learning assessments. Claiming that conventional methods stress individual courses or programs, rather than encompassing a company's learning ecology, a new corporate version of Sloan Pillars is proposed. The authors claim that their holistic approach--assessing employee access, learning and cost effectiveness, and learner and management satisfaction--provides companies with the tools they need to assess the effectiveness of company learning efforts overall.
