The Handbook stands alone as a rigorous, evidence-based Body of Knowledge under the banner of the International Society for Performance Improvement’s “performance landscape,” and for the first time provides a unified and authoritative compendium of standard principles and best practices for improving productivity and performance in the workplace. Featuring best-in-field researchers, thinkers, and practitioners across several disciplines and geographic boundaries, each volume provides a current review of all information presently available for the three core areas of improving performance in the workplace: Instructional Design and Training Delivery; Intervention Selection and Implementation; and Measurement and Evaluation.
