I've been applying the Business Model Canvas to show how under a rapidly changing business environment the BM of the company I work for needs adjustment. 

There are several options for Canvas-formats, but I didn't find one for the environmental analysis. So, I made one in Google Docs and it helps me to get the message across. 

I hope it works for you too. If it does, please rate it. 

Find the format for the Business Model Environment here.
