If you want me to adopt a new technology, make the advantages clear. You want me to use a campus-wide events calendar? Show me the stats to demonstrate how visible the central calendar will be and mention the larger number of people who will find out about my event. You want me to use a new CMS? Convince me that new features I’ve been asking for are there and will make web editing easier and more convenient.
If you can’t come up with benefits to persuade your end users, you’ll have an uphill battle. And, perhaps, you’re implementing the wrong technology.
