To rewind just a bit, my former colleagues at NCRI created a form of scenario planning called Future Mapping that improved upon scenario processes pioneered in the business world by Royal Dutch Shell. After I had departed for Silicon Valley, they continued a series of public workshops on The Future of Information Commerce. The results are available here via Internet Archive's Wayback Machine. An overview of what I call (for trademark reasons) the Scenario Mapping process is provided in this presentation.
Working in teams, workshop participants decide which of 150 plausible Events provided by the facilitators Must or Must Not happen if the team's assigned outcome or Endstate is to be realized. Events that are Common to a majority of scenarios are called Common Events. These are worth added attention because, generally speaking, more industry stakeholders have an interest in these Events. In the 1997 workshop, 12 events appeared in a majority of scenarios. Here they are with my comments.
