Another decent piece this from Baldur:

Finally, once you have a set of ideas and aspirational projects, you need to whittle them down, or at least prioritise them. That means you need to look at the cost-revenue balance for each one. And to do that you need to figure out the business model, often from scratch because, unlike print, interactive media doesn’t come with a business model attached.
