Measuring Performance in Dynamic Decision Making: reliability and validity of the Tailorshop simulation.

The Tailorshop simulation is a computer based dynamic decision making task in which
participants have to lead a fictional company for twelve simulated months. The present study
investigated whether the performance measure in the Tailorshop simulation is reliable and
valid. The participants were 158 employees from different companies. Structural equation
models were used to test tau-equivalent measurement models. The results indicate that the
trends of the company value between the second and the twelfth month are reliable variables.
Furthermore, this measure predicted real-life job performance ratings by supervisors and was
associated with the performance in another dynamic decision making task. Thus, the trend of
the company value provides a reliable and valid performance indicator for the Tailorshop
simulation.
