This chapter discusses several topics related to evaluating IT investments and assessing productivity impacts, including:
1) The productivity paradox where measured IT investments do not always correlate with measured increases in outputs.
2) Approaches to evaluate IT investments including traditional cost-benefit analysis using NPV and ROI, as well as considering both tangible and intangible benefits.
3) Challenges in accurately assessing costs of IT investments given fixed costs and life cycle costs that accumulate over many years.
