Besides Ideation and Information, you need some other stuff too.
To maintain the alliteration, but stretch the semantic, then I’d say this is:
  • Itinerary. What are you seeking to accomplish with the review?
  • Implementation. If the idea is good, and the information is valid, what’s the “cost” (in a resource, time, trade-off etc. sense) for approving the itinerary?
  • Indication. How do you know what success looks like? Measures, answered questions etc. all form the scope of success.
So there we have Marc’s 5 Is for the development of exec review material... Ideation, Information, Itinerary, Implementation and Indication.
