The Human Factors Model

The model presented in this module is adapted from David Meister's, Human Factors: Theory and Practice, 1971, and is one depiction of how humans and systems interact. Environmental influences on that interaction have been added.  The model illustrates a typical information flow between the "human" and "machine" components of a system.   This model will be used to introduce all of the other course modules.
