I spent the last week trying to convince a group of people to use a cloud based word processor instead of the traditional desktop in order to avoid common problems of email exchange. What I thought would be time-consuming - being online to offer assistance should they find any problem using it - turned out to consume a lot of my time to actually make them use it.
Although they did end up using the cloud based tool, and even liking doing so, it required a couple of Scarlett Johanssonn pictures as - what I like to call - illustrative argument, which was awesome to add some humor to the heavy atmosphere caused by all the arguing.
I don't think I can keep using the same strategy in future attempts with different people, especially with those who fit in the late adopters and laggards in the Everett Rogers diffusion of innovation scale. So what kind of strategies could have been used to convince a group of people to at least try the new system with one project? Assuming, of course, that you didn't have the authority to impose it.
