DIEGO NAVARRA, DR. diego.navarra@euruni.edu
‘In time of rapid change, strategic failure is often caused by a crisis of perception (that is, the inability to see an emergent novel reality by being locked inside obsolete assumptions), particularly in large, well-run companies’
Pierre Wack

Assumptions of scenario planning 1. Managers are not able to make valid
assessments of probabilities of unique future events
2. Best guesses of the future may be wrong
3. Minority opinions should be allowed "airtime " .

What are scenarios?
• A scenario is not a forecast of the future -multiple scenarios are pen pictures encompassing a range of plausible futures
• Each scenario has an infinitesimal probability of occurrence, but the range of the set of scenarios is constructed to BOUND uncertainties seen to be inherent in the future
• Unlike probability judgments, scenarios highlight the reasoning underlying judgments about the future

More on scenarios
• A major focus is how the future can evolve from now to the horizon year
• Relationship between critical uncertainties, predetermined trends and behavior of actors are thought through.
• Decisions are then tested for robustness in the 'wind tunnel' of the set of scenarios.

Scenario construction: the extreme world method
1. Identify the issue of concern & horizon year 2. Identify current trends that have an impact on the issue of
concern 3. Identify critical uncertainties 4. Identify whether trends & uncertainties have a negative or
positive impact on issue of concern 5. Create extreme worlds 6. Add predetermined trends to both scenarios 7. Check for internal consistency 8. Add in actions of individuals & organizations
Examples of predetermined trends
Demographic: population growth, birth rates Technology: growth rates, production
capacity Political: power shifts, budget deficits Cultural: changing values, spending
patterns Economic: disposable incomes, investment
levels

When should a company use scenario planning?
1. When uncertainty is high 2. Too many costly surprises have occurred in
the past 3. Insufficient new opportunities are perceived
or generated 4. The industry has experienced significant
change, or is about to 5. Strong differences of opinion exist, each of
which has its merits

Typical outcomes of scenario planning
• “This is what we have to do” (developing new business opportunities)
• “We better think again” (understanding outcomes of plans better)
• “ We better watch those dots on the horizon” (perceiving weak signals of new
developments) • “We are in the right track”
(moving forward with more confidence)
