A variety of disciplines contribute to the practice of HPT as we know it today (Stolovich & Keeps, 1999).
By systematically applying knowledge and resources from these fields, practitioners help organizations find practical solutions to performance problems. Many different models exist to assist these professionals in communicating and applying the concepts of HPT in order to reach this goal. The HPT model illustrated below (adapted from Van Tiem, Dessinger, & Moseley, 2000) provides a comprehensive framework for the application of HPT principles. It considers the many complex and interrelated factors of performance through phases of analysis, intervention design and implementation, and ongoing evaluation.
Other models for performance improvement address these phases from slightly different perspectives. However, regardless of the details and differences between models, all share the common first step to performance improvement...analysis.
