A relative once bought a very expensive camera.
However, she found the number of new features confusing. So she simply used all the default settings. Her photos turned out the same as her old camera.
This happens a lot in communities too.
When you move from an inexpensive to a premium platform, you have a lot of new features and settings to fiddle with. Many (perhaps most?) organisations are nervous about making tweaks and simply use the default settings. Unsurprisingly, they don’t see the results they were expecting.
Some things to consider here:
First, don’t confuse a default setting with the best practice. The default settings aren’t the combined wisdom of the platform’s many years of experience (trust me, I checked). They’re no better than the default settings on a camera or the default ringtone on your phone. They’re simply settings that you’re expected to change to suit your needs.
Second, there isn’t much point upgrading to a new platform if you’re not going to invest time and money learning how to use it properly. You need to set aside time in your calendar to learn how to do this. This is time-intensive but it’s the entire point. When you move to a new platform the slight change in how members can talk to one another pales in comparison with the extra new features you’re paying for.
Third, take the courses offered by the vendor, have a staging site where you can fiddle with the settings, talk to others using the same platform. Take what’s likely to be a big weakness and turn it into your biggest strength.
