Abstract

The results from the study described in this paper suggest that customer expectations of a project's total cost can have a very large impact on human judgment-based estimates (expert estimates) of the most likely use of software development effort. The information that the customer expectations are not valid estimation information did not remove the impact. Surprisingly, the estimators did not notice this impact or assessed it to be low. An implication of the results is that the provision of realistic project estimate of most likely use of effort may require that the estimators do not know the customer's expectations of the total cost of the project.
