I worked for a company that was working on rolling out D365 for 2 years :) I was acquired by a company that was working on Sales Force integration for 3 years, I left before it was fully functional. They had 4 full time devs working on Sales Force, meanwhile we had built the entire company in a year with 4 devs.
