This approach is flexible and adaptable, intended to spark and then sustain debate.
It is a very pragmatic approach, taking as a starting point
the observation that the desired data are never available, but
that the issues are pressing and analysis must proceed. It then goes on to point out
that a great deal can be learned from the existing data, so it is worthwhile to start
Another pragmatic feature of this approach is that scenario narratives are created
by a stakeholder group and the client in reaction to a provisional scenario proposed
by a scenario team. This follows from the common experience that people who are not
scenario experts have difficulty talking about the future in a vacuum, but
can easily discuss the future if a concrete example is in front of them.
