I am evaluating an existing on premise finance application vs an alternative online based application. This will be done via technical assessment of both applications and decide which meets business requirements and present a better overall business value.
I need your help in adopting a "Scientific" approach in selecting the best fit application. Are there any comparison frameworks I can use? The board wants "evidence" of why chosen solution is better than other one.
How do you go about such exercise in a structured approach?
Your help is much appreciated.
