评论了Quinn和Baily关于信息技术提升服务业生产力的研究，指出其控制IT成本的建议无助于解决IT投资评估问题，且量化收益的难度随成本扩大而增加。
The article presents a commentary on the article “Information Technology: Increasing Productivity in Services,” by James Brian Quinn and Martin Neil Baily. The author contends that the suggestions outlined in the research for controlling information technology (IT) costs will do little to ameliorate the problems that surround the evaluation of IT investments. He notes that the difficulty of quantifying the benefits created by investing in improvement programs is heightened as costs expand beyond pure hardware and software expenses.
