Technology Investment Models and Methodologies
Conclusion: There is no single perfect financial analytical method. There are some models which are in common use but their longevity is due to their lack of rigour, or that they can be used for any occasion.
The best way to avoid the obvious gaps is to combine techniques, not in one model, but for comparison purposes. By bringing together parts of the stronger methodologies users can obtain better insights. How this type of optimised composite model will work is shown in the next paper.
