MANAGEMENT
SPECIAL How to confront uncertainty in your strategy
Lack of
certainty about the future is the very reason you need a strategy. Instead,
embrace probability.
“Predictions are difficult, especially
about the future,” quipped Yogi Berra (and, before him, physicist Niels Bohr).
This rings especially true for those trying to run a strategy process.
Uncertainty is not only everywhere in and around strategy—it is the very reason
we need strategy. Without uncertainty, we would just need a plan to go from A
to B.
In running a business,
there are many elements that you just can’t control—the fate of the economy,
political events, your competitors’ actions. Yet uncertainty is rarely
accounted for in a clear and robust way in the strategy room. Even proper
planning for different eventualities is often missing from the discussion.
Instead, we typically prepare for one version of the future, often without
understanding how likely that version is to become reality.
Strategy requires
confronting uncertainty head-on by embracing the notion of probability. In our
new book, Strategy Beyond the Hockey Stick: People, Probabilities, and Big Moves to
Beat the Odds (John Wiley &
Sons, February 2018), we focus on the importance of calibrating the odds of a
strategy succeeding, by building in explicit trigger points to reexamine decisions
as we learn more and by applying the probabilistic approach to how we evaluate
performance afterward. By understanding the chances your strategy has of
succeeding before you start to execute it, and knowing how those odds change
based on specific actions you take, you can tackle uncertainty with hard
empirics, not guesswork or wishful thinking.
Why do we shy away from
dealing with uncertainty? The root of the problem is our tendency to view
strategy as a purely intellectual exercise—a sort of corporate game of chess,
perhaps even played in three dimensions by its best practitioners. However,
strategy poses the kind of low-frequency, high-uncertainty problems for which
the human brain is least adapted. People are prone to many
well-documented unconscious cognitive biases—overconfidence, anchoring, loss aversion, confirmation
bias, and attribution errors, among others. These unintentional mental
shortcuts exist to help us filter information for day-to-day decisions, but
they can distort the outcomes when we are forced to make big, consequential
choices, infrequently, and under high uncertainty—exactly what we confront in
the strategy room.
Even the most seasoned
executives have only limited experience and pattern recognition in these
situations. They must make decisions based on limited information, and results
may not show up for years. In the meantime, any number of factors—human,
market, lag, and “noise”—can intrude and overwhelm any strategist’s ability to
predict an outcome. Trying to improve your strategic decision making is like
trying to improve your golf game by practicing blindfolded, and not finding out
if your ball went into the hole for three years.
How we (fail to) deal with uncertainty
Spreadsheets aren’t
built for odds and ranges. They are built for specific numbers, so it’s hard to
deal with a 75 percent chance that a value will be between X and Y—multiplied
by the thousands of cells in a corporate budget. US president Harry Truman
famously said he wanted a one-handed economist so he would no longer have to
hear his advisers saying, “On the one hand this, on the other hand that.”
Over our time working
with hundreds of clients, we have seen many tactics that executives use to
acknowledge the issue of uncertainty without really dealing with its
implications. Here are some of our favorites:
We ignore uncertainty.
Many strategy
presentations start with an analyst-based projection of the market. Not a
scenario, not a range of outcomes, but the “most likely version of the future.”
And that’s the last thing you hear about uncertainty in the presentation. From
then on, you get single-point estimates for the plan. “I can’t handle multiple realities,”
one CEO told us. “I’d rather pick the world I live in.”
We treat uncertainty as
an afterthought.
The strategy room is a
harsh place for most, and, quite frankly, failure on that stage is not an
option for most managers. Execution problems? OK. A strategy that has gaps? We
can fix that. But a strategy conversation about probabilities? You must be
kidding! What you get instead is a slide about risk on page 149 of a 150-page
deck, titled something like “Potential risk issues and how to mitigate them.”
It’s there just so the presenter can say the issue is covered should the
question about risk pop up.
We pretend to deal with
uncertainty.
In some cases,
uncertainty is actually discussed in the strategy room. Say, geopolitical
upheaval is threatening sales growth in an emerging market, or there are signs
that a competitor may make an industry-consolidating move. A few scenarios may
be presented, followed by a discussion about which of them is more or less
likely to occur. Then one scenario is selected as the “base case,” and that’s
probably the last thing you hear about uncertainty. Strategy clear, job done.
There are, of course,
businesses that could not survive without dealing with uncertainty. For
example, in asset management and other financial businesses, risk-weighted
metrics are normal. The difference is that these professionals are moving money
around. In more tangible businesses, you move around not just money but also
people, along with the careers and reputations of business leaders. While the
calculator loses reputation by wrongly calculating risk, the manager loses
reputation by giving up resources.
All these common
practices and related errors can lay the foundation for setting the wrong
ambition levels and, consequently, creating flawed strategies. There is nothing
wrong with having bold targets, but those ambitions
need to be anchored in the realities of the business and the evolving context
in which it operates.
Understanding the reasons for outcomes
At some level, it is
easy for the CEO to deal with uncertainty by playing the portfolio game of
spreading investment like peanut butter around numerous businesses, knowing
that not every bet has to pay off for the total plan to work. The problem is
that a portfolio game on the corporate level becomes a matter of all-in
commitment for an individual-business-unit leader. We have all heard the
saying, “You are your numbers.” The saying isn’t, “Well, that project only had
a 50 percent chance of success, so I won’t hold failure against you until
you’ve had another similar failure or two.”
Assessing the reasons
for a given outcome isn’t always easy. We may not be able to tell if a poor
result was a noble failure, just as we can’t tell if the great result was blind
luck. Was it a case of best efforts on a good bet that were foiled by a bad
roll of the dice? Was it a more pernicious failure of planning or execution?
Was it, perhaps, just a bad strategy to start with? Uncertainty doesn’t only
mean we can’t see around the next corner; uncertainty also invades the past.
When deciding
incentives, bonuses, and promotions, uncertainty and probabilities again come
into play. Since we all want to succeed, most of us will vastly prefer a P90
plan (one that we will hit with a 90 percent chance) over a P50 plan (which we
would hit only 50 percent of the times we try). In fact, many business leaders
would quietly admit that they only agree to budget targets that they feel they
can hit them almost for sure (P100), save any completely unexpected
disruptions. Yet, when we ask CEOs what would be fair with respect to misses,
many of them say that every three to four years a leader can be expected to
miss a plan if the plan has been stretched enough—say, P60 to P75. This is a
big difference in perspective.
Accounting for
probabilities can make evaluating performance and outcomes uncomfortably
complex, with key performance indicators much harder to specify. The situation
resembles the FBI office that learns a gang intends to rob one of three banks.
The head of the office dispatches teams to all three banks to catch the
thieves. Obviously, only one team will capture the gang, but the entire unit
should receive the praise and rewards. Yet we know that, most of the time, only
those who are in the right place at the right time will be lauded as heroes.
From certainty to probability
To counter these
predilections and help companies get a grip on uncertainty, we decided to bring empirical analysis to
the assessment of probability in strategy. By examining dozens of variables for
thousands of companies over more than a decade, we identified levers that
explain more than 80 percent of the up-drift and down-drift in corporate
performance. Using these benchmarks, CEOs and boards can dispassionately assess
a strategy’s odds of success before signing off on it.
First, we plotted the
economic profit of almost 2,400 companies on a graph. The resulting power curve
shows that companies in the top quintile capture nearly 90 percent of the
economic profit created—some 30 times as much as those in the middle three quintiles.
We found that your
industry’s performance is responsible for almost half of your position on the
power curve. Industry impact is so substantial, in fact, that you would be
better off as an average company in a great industry than a great company in an
average industry. But here is the kicker: mobility on the curve is possible—but
rare. The odds of a company moving from the middle quintiles to the top over a
ten-year period are just 8 percent.
Additionally, we found
that 10 variables explain nearly 90 percent of a company’s position on the
power curve. They fall into three categories: endowment (what you start with),
trends (the headwinds or tailwinds you face), and moves (five strategic actions
you take). By benchmarking your company’s starting point, the trends it faces,
and the moves you plan to make—against what our research shows is necessary to
move the needle on the power curve—you can gain a precise probability score of
your strategy succeeding. The results allow you to shift the conversation from
single-point projections to probabilities.
Sometimes, even a
simple calibration can stir a discussion on probability. One consumer-goods
client set itself the target of achieving double-digit growth. The company did
a great deal of planning, and the aspiration looked reasonable, but the
client’s actual odds of success hadn’t entered the discussion. The plan was
based on an inside view, built up from the
combined estimates of each business unit.
A simple bit of
research made the company reconsider. Publicly available information showed
that, of industry peers within the same revenue range as our client, only 10
percent generated sustained double-digit growth over ten years. The question
became: Is our strategy actually better than 90 percent of our peers? Really?
What makes us stand out, even though we performed liked an average company over
the prior five years, growing in the mid single digits? Bringing the actual
odds into the strategy room made for a tough moment with the management team,
but it did recalibrate the conversation in important ways.
Embracing this approach
can be difficult for some teams. Companies in the top quintile tend to think
that’s where they belong. After all, they worked hard to get there and have
developed impressive advantages over the competition. Yet roughly 40 percent of
companies at the top of the power curve will slide down over a decade, our
research shows. Likewise, companies in the middle quintiles tend to believe
that they can move up. Is there a chance that they will drop to the bottom
quintile—why bother to even consider that possibility?
So how do you create a
strategy process that embraces probabilities? In any game, as in business, your
goal must be to give yourself the best possible odds. If five companies each
have an 80 percent chance of succeeding, that still means that one will usually
fail. If five companies each have a 20 percent chance of success, one of the
five is still likely to win. Clearly, the superior strategy is the one with an
80 percent chance of success, and this is the one that should be given the
credit, no matter whether you win or lose.
Risk, of course, needs
to be part of the probability discussion. With odds comes the explicit
realization of risk, and loss aversion kicks in. Directly confronting risk can
make people gun-shy, even when we want them to take more risk.
Assessing the risk is
essential to deciding when they are worth taking and in pushing others to take
them. If you have just a slim chance of winning, but a bet costs you little and
the potential win is huge, that may still be an investment worth making. The
converse is true, too. An expensive investment that generates a high probability
of a small success may be a bad idea. Poker players refer to the calculations
as “pot odds.” If a $100 bet gives you a 20 percent chance of winning a $200
pot, you fold. Essentially, you’re paying $100 for $40—that 20 percent of the
$200. But a $100 bet that gives you a 20 percent chance of winning a $2,000 pot
is one you make every time, because you’re paying $100 to get $400—20 percent
of $2,000. So, an assessment of your odds—competitive, market, and regulatory,
among others—needs to be part of your calculation.
It’s also essential to
track assumptions over time. A few short weeks after the plan is developed, the
detailed assumptions go into a fog of memory. The variance to budget gets
tracked very carefully, but the underlying assumptions—such as uptake rates,
market growth, or inflation rates—are not assessed as carefully. Rather, decide
what you can today, with the information you have, and build explicit trigger
points into the strategy to revisit decisions as new information surfaces.
We need to stop
developing strategy as though we know the future. By calculating your chances
of success, you can see if the plan you are asked to approve is based on a
realistic aspiration or distorted wishful thinking. With an objective benchmark
for calibrating your odds, you and your team will understand the strategy’s
probability of success before you leave the room, much less before you begin to
execute it.
