The first part of this post is over at Culture Hacker.
The diagram below shows provides an overview of the workflow for delivering a transmedia project. You can view a better quality version here.
Many of my earlier posts have looked at the development phase where we're trying to define the entertainment we hope to provide. This diagram looks at the full spectrum of activity from scoping your idea to delivering it.
The process has been developed with brand clients in mind but it's easily adapted for filmmakers creating transmedia for themselves. What's nice about this workflow is that there's a tollgate at each phase - allowing the client to sign off on the project before moving to the next level of detail (and hence cost).
If you right-click this link and "save as" you can download a project reference template (the "bible") that's already structured with this workflow.
Please let me know if you think you've found anything in delivering working transmedia entertainment that's not covered.
