Structural equation models incorporating unmeasured variables make possible the rigorous testing of theories previously difficult to test adequately because of fallible measures of the theoretic variables. This paper first discusses a simple causal model; incorporating a single unmeasured variable for the purpose of exposition. A substantive…

The retrospective case history is a little-used, but very valuable tool in organizational theory research. It is particularly useful in illuminating variables in an organization's development which, in controlled experimentation, would require prohibitively long periods of time to materialize. Additionally, the technique is useful for generating a…
