Risk identifi cation and mitigation
The cost/benefi t analyses will narrow your fi eld of potential solutions. But
before you choose one, run another round of tests. “You’ve based every line
of your spreadsheet on assumptions—which you’ve carefully documented,”
write Sheen and Gallo. “But what if they’re wrong and things don’t go as
planned? What if the worse (or best) case occurs?” This “what if ” process of
analyzing your idea is invaluable.
To answer these questions, reexamine all of the beliefs that under-
write your estimates. What if a construction project runs over? What if
a new competitor enters the market? What if there’s a global economic
slump next year? Estimate out how each alternative scenario affects the
value of your project. You may fi nd that your best plan is actually very vul-
nerable to risk and choose to redevelop your second-best option. Or per-
haps the major threats to success on this project mirror a recent disaster
within the company, and you need to show why your project won’t fail in
the same way.
Don’t be gentle with your model. The decision makers certainly won’t.
They may not be as well versed as your team in the numbers, but they’re
probably experienced—and imaginative—when it comes to evaluating risk.
If they have a fi duciary duty to the organization, they’ll be extra cautious.
Keep their perspectives in mind as you consider the box “Risk factors.”
Generate a long list of potential risks and enter them into a spreadsheet.
To identify the biggest threats and opportunities, Sheen and Gallo suggest
scoring each risk on its probability and its potential impact. (Weather de-
lays in winter: possible, but not likely to hold up a schedule by more than
a few days. Asteroid collision: vastly more devastating, vastly less likely.)
Multiply these two numbers together for each risk, then methodically
comparing the results when you swap in the best- and worse-case values.
Ultimately, says Sheen, “[y]ou’re likely to choose a middle number for most
lines, but you may have reason to be conservative or aggressive on cer-
tain items. If one of your critical stakeholders is risk-averse, for example,
you may go with lower numbers on your benefi t stream. If you face severe
