本研究以系統的觀點探討軟體公司在成長時所面臨的管理挑戰。系統觀點主要著重於公司成長歷程中政策、行動與條件之間的相互影響關係，以及因而所產生的成長循環與破壞性循環。基於對個案公司ERP事業部門成長歷程的研究，發現軟體公司的成長循環會不經意地引發長、短期成長之間的衝突，使公司陷入獲利下降、工作負荷過高與研究發展延遲的破壞性循環，形成所謂單發式成長(one-shot growth)的現象。我們建立了個案公司ERP事業成長的系統動力學模型，深入了解與解釋成長循環與破壞性循環的歷程。我們也進一步探討深植於軟體公司的一些基本假設，並進行不同成長政策的測試。然後提出能平衡長、短期成長、以及避免破壞性循環產生的成長政策建議，以改善單發式成長的行為形態。文中亦對單發式成長行為的關鍵結構及其管理意涵進行更進一步的延伸討論。

The purpose of this paper is to study the one-shot growth problem of software company. A major ERP software house in Taiwan, Company Wei-Yuan, has been chosen as the target. With more than ten individual interviews with company Wei-Yuan's CEO, head of ERP department, ERP marketing manager, and several staffs including programmers, system designers, and system analysts in four months, a system dynamics model of the Company Wei-Yuan's one-shot growth was built. The model structure has been recognized and accepted by interviewees using both qualitative and quantitative diagrams during and after the modeling process. Suggestions to improve the one-shot growth problem are proposed. We propose a mechanism to balance the conflicting short-term and long-term growth forces by designing an index to guide human resource allocations. Simulation has shown that the problem of one-shot growth can be eliminated with the simple mechanism. The paper further suggests the existence of a generic one-shot growth model and calls for future research along this research direction.
