    摘要: 承諾升級（Escalation of Commitment）現象是指當決策者面臨一連串的失敗發生且狀況陷入困境時，仍有較高的意願選擇持續這項未完成的事件，此現象在軟體專案執行或軟體開發過程中亦時常發生。其狀態通常面臨困難，但決策者可能因各種因素考量而堅持讓該專案持續進行。本研究以沉沒成本效應與趨避理論中的專案進度的觀點，探討此兩項普遍軟體專案執行狀態對承諾升級決策的影響。研究結果發現，投入成本越多，承諾升級現象發生的可能性越大；專案進度越快，承諾升級現象也越可能發生，但在該專案兩項因素同時考慮的狀態下，專案進度雖然仍會使承諾升級現象發生，但相對地，成本投入越多，決策者繼續該專案的意願卻越低。由此本研究可以推論，在專案發生困難時，若著重於考慮沉沒成本或專案進度單一因素，都可以解釋承諾升級的現象，但若兩者同時考量時，決策者會將沉沒成本與專案進度相互比較，根據該專案未來成功的價值是否大於未來成本投入，來決定是否該繼續此專案。
    Escalation of Commitment is a phenomenon that when a project has been in a serious condition, the decision makers still want to continue the project. This phenomenon can be found in MIS projects and software development projects. The purpose of this research is to investigate why escalation of commitment occurs from the sunk cost and project progress perspectives.
    In this study, we designed and conducted a simulated experiment that includes three different levels of sunk costs and three levels of project completion to ask subjects’ intention to continue the project. We find that the intention to continue the project gets higher, when the sunk cost or project completion is higher. However, the interaction effect exists when both factors are put into consideration. In this condition, the decision maker may judge the benefit of completion as compared with the additional cost that needs to be invested.
    Our results indicated that both of sunk cost and progress of project can be used to interpret the decision behavior of commitment escalation. When both factors exist, the mismatch between cost and project completion may be the main factor. The escalation of commitment is more motivated by the degree of completion than the sunk cost.
