As the rate of change in the operational environment outpaces the development of doctrine and schoolhouse instruction, Army leaders must direct their own development in order to adaptively and professionally meet the challenges brought on by Army transformation. Army Structured Professional Forums (SPFs), powered by advances in collaborative toolsets and multimedia presentation software, provide a means for self-development and professional growth. Systematic assessment of the functioning and impact of SPFs is critical for ensuring that SPF activity is aligned with organizational goals and producing return on investment. Assessing the impact of an SPF requires identification of those performances that activity in the forum can reasonably be expected to influence. In this paper, we present an approach for evaluating the functioning of SPFs and identify several candidate metrics for assessing the impact of SPFs. These serve as a foundation for organizing an effectiveness analysis of SPFs, and provide a general method for assessing SPF impact at the individual, unit, and organizational level.
