I'm not sure if you've seen this meme but I've come across it in several books both about online and offline communities:
Interactions in communities -->
Creates Understanding --------->
Develops Trust ----------------->
Allows Exploration & Entreprenuership ->
Sets stage for Innovation
The most recent place I saw this meme again, in a slightly varied form was near the last chapters of The World is Flat (ok, maybe I make references to this too often these days :)
Now these are "grand" notions that often follow in a sequence like this above. You need to have one stage happening before you can really reach the next stage. Thus you don't really jump ahead and ask "How do we innovate?" but need to ask "What are we doing to set up an environment such that innovation can happen?"
It's important to realize that the arrows in the diagram above are not trivial. In other words, when you have one stage, you need to do something to progress it to the next stage. That something could take a whole lot of effort. But in terms of managed innovation, it gives points where you can measure how your population is doing and how you can recognize if you've reach that stage.
There are many books out there describing how to innovate and get others to innovate, and I certainly have not read nearly enough of them. I still wonder if some of them consider going through that meme sequence above.
The somethings are also where the opportunities lie. Many innovation and leadership management trends have come and gone, and still many exist in parallel. I'm no certified expert at it and there are likely some really good sources out there too. (Okay, maybe people like Steven Covey)
Right now, I'm just trying to develop an idea for the early stages of this meme, those focused on the developing the community. Hopefully more smart people will come along to explain what to do next.
From communities to encouraging innovation
