ABSTRACT
To properly design an error-management or error-proofing strategy, it is essential to understand the functions of and reason for designing a product, system, or process. Designers strive to eliminate errors when consumers use their products and when workers manufacture and assemble products in a production system. However, in an educational or training system, where people learn by making mistakes, one should error-proof those elements of the process not critical to the learning objectives, and then manage the errors in the process segment associated with the educational objectives so as to facilitate the educational process. However, even in such educational and training settings, it is important to error-proof activities and processes not directly related to the educational objectives. Hence, this discussion focuses on error-proofing strategies and techniques.
