...once the strategic decisions are identified on the DECISION HIERARCHY via an ISSUE RAISING session, and a better picture of how they relate to the UNCERTAINTIES and VALUES are clarified on a DECISION DIAGRAM, we can generate alternatives.
An alternative should be doable while bringing the highest possible value.
Having multiple strategic decisions (to be made now) and having multiple paths available for each decision means that a large number of alternatives are possible. But not all of those alternatives are going to be feasible or will make sense. Furthermore, decision makers usually come up with alternatives that are slightly different from each other. However, in order to unlock more value, it is important to look at the extreme possibilities that would give insight on how to find an alternative that is more valuable.
Documenting each alternative:
While building a strategy table, keep in mind that generating EDGE ALTERNATIVES would help you explore the possibility of creating more value.
