Prior research in IS project manager decision making used students as surrogates for project managers and manipulated sunk cost and alternatives to examine their influence on project management decisions (Keil and Mixon 1994; Keil, Truex, and Mixon 1995). The research design for this project uses working project managers as experimental subjects, rather than the student subjects used by Keil, Truex, and Mixon (1995). Keil, Truex, and Mixon’s subjects were students who assumed the role of IS project managers. In the design used here, working IS project managers served as subjects in order to ascertain if actual practitioners react differently to the experimental manipulations.
