IT Investment Models
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 them may not convince other parties if the tool is not compatible with cross-department interpretation.
