Comparison of Investment Analysis Models
Conclusion: There are several established models which have been used to evaluate technology investments. Some models are applied to assess the value of technology in use within an organisation.
Organisations can select a model for a particular need; however it is fundamental that the assumptions and the factors that construct the model are realistic and clearly understood. Furthermore, the models should be comprehended by other departments within an organisation, such as finance. A model that is only applied within, and solely has merit for IT is generally not an altogether useful tool. The outputs and the inferences drawn from these outputs may not convince other parties if the tool is not compatible to cross-department interpretation.
