I am working on my paper for JWI 531 Financial Management II at Jack Welch Management Institute. We have to evaluate the strength of Salesforce.com moat in our Moat Analysis paper. I am stuck!

I have to show financial data or a ratios and explanation for the Life cycle Stage of Fading Returns and Competitors Barriers to Entry. Do you know which ones I would look at and what I am looking for to show these? And how to potentially find charts that might demonstrate it (not necessary though).

Thank you!
