Great presentation and such a true story. Had a conversation with a friend of mine a few days ago: His company made the political motivated decision to go Microsoft. Obviously some ROI figures were calculated and a complete migration including the applications was planned in a given timeframe. Now, years after the Notes-Apps are still vital for the business and running. The employees have both clients on their desktop. The company still has both licenses. And of course now nobody is re-calculating and questioning the ROI of a failed migration … Currently we see our friends telling again the story, how easy an migration is, now into their new cloud offerings. Same arguments, same potential to simply fail!
