Phase 5 - Evaluation

The ISD process stresses evaluation and improvement throughout the life cycle of the operating system for which the training was developed. This is accomplished by training evaluation and iterative feedback for instructional program improvement. Trainee on-the-job performance is measured periodically to quantify the positive training transfer and measure instructional program success. A critical element of the evaluation phase is development of appropriate metrics to support this post training evaluation process. Three evaluation categories support the ISD model.

• Formative Evaluation - Consists of the process and product evaluation performed during the analysis and design phases. It also encompasses the development phase validations including individual and small group try-outs, but excluding the final summative evaluation/validation.
• Summative Evaluation - Consists of operational tryouts that are conducted as the last development phase validation of the instructional program.
• Operational Evaluation - Consists of the operational system evaluations that are performed both internally (in classes) and externally (on the job) on a periodic basis during the implementation phase.
