Virtually all government and industry information and control systems rely upon computer professionals for systems development and maintenance. With the national workforce growing at only one percent annually and enrollments in computer and information sciences college programs declining, the need exists to obtain a continued contribution of good work from our existing workforce. A multiple-phase, multiple-case study research project was performed to develop an understanding of how technical currency is maintained, not as a discrete phenomenon, but within the setting of the work environment, considering project experiences, organizational relationships, professional preparation and continuing professional education, and individual motivation. Previous research indicated that project experiences contributed to, or provided a vehicle for, maintaining technical currency. Maintaining technical currency was found to require a continuous process involving organizational relationships, the individual's perceived value in the organization, constant assessments and evaluations of current and desired project involvement or position attainment, repeated and varied learning episodes, and actual project experiences. Individuals were motivated to take specific actions, such as participating in training courses, when such action was expected to yield a benefit. Project experiences alone were not sufficient to maintain technical currency, although they were an essential element. While formal education in preparation for a career was critical, formal courses did not contribute as significantly as other forms of continuing professional education to maintaining technical currency. A Technical Currency Model was generated that explains how individuals expend energy in one or more of five focus areas depending on their motivation at the time: (a) technical qualification for a project or position; (b) political qualification for a project or position; (c) performing on a project or in a position; (d) determining that change is appropriate; and (e) seeking the next project or position. / Ph.
