Introduction
You make countless choices every day, yet few schools teach you how to make them effectively. Poor decisions often lead to regret, lost money, and missed opportunities. You might rely on gut feeling or simple intuition when facing complex personal and professional challenges. This approach frequently fails because human brains struggle with overwhelming information and hidden psychological traps.
John S. Hammond, Ralph L. Keeney, and Howard Raiffa argue that decision making is a skill you can learn and master. The authors introduce the PrOACT framework, a practical system that breaks any decision down into eight core elements. You will learn how to frame the problem correctly, state your objectives, and create imaginative alternatives.
The book guides you through evaluating consequences, making tough tradeoffs, and managing uncertainty. You will also discover how to navigate linked decisions and avoid common psychological traps that sabotage your best intentions.
As you read, you will find answers to several critical questions:
- How do you define the real decision problem instead of a symptom?
- What separates fundamental objectives from mere means objectives?
- How can you handle risks and uncertainty without guessing?
- Why do psychological traps distort your judgment without your knowledge?
1. Framing the Problem
Complex decisions can be successfully managed by breaking them down into eight core elements using the PrOACT approach. The acronym stands for Problem, Objectives, Alternatives, Consequences, and Tradeoffs. Three additional elements, Uncertainty, Risk Tolerance, and Linked Decisions, help clarify choices in volatile environments.
The way a decision problem is stated frames the entire choice, determining which alternatives are considered and how they are evaluated.
Starting from the wrong problem definition leads to poor solutions even if executed well. You often fall into the trap of laziness by stating problems in the obvious way or letting external triggers bias your perspective without questioning underlying constraints.
Bob Hamonski lost his job in Portland when his company was acquired and accepted an analyst position in Seattle to stay with the employer. This created a nightmare for childcare because he failed to frame his problem around getting a job in Portland.
The PrOACT Approach
To work through major dilemmas, you must apply a reliable set of steps:
- Work on the right decision problem
- Specify your objectives
- Create imaginative alternatives
- Understand the consequences
- Grapple with your tradeoffs
- Clarify your uncertainties
- Think hard about your risk tolerance
- Consider linked decisions
Defining the Problem
Every decision problem has a trigger which is the initiating force behind it, often originating from outside circumstances. To evaluate a trigger properly, you must follow specific actions:
- State your assumption of what the decision problem is
- Identify the triggering occasion
- Establish the connection between the trigger and the problem
Creative problem definition allows you to transform difficult circumstances and compliance mandates into valuable opportunities. By looking beyond the obvious form of a problem and asking what can be gained, you unlock innovative alternatives and operational breakthroughs.
Challenging Constraints
Problem definitions usually include assumptions and constraints that narrow the range of alternatives. While some constraints help focus choices, others restrict creative thinking and hide superior paths until actively challenged.
A snowboard manufacturer planning a northeastern United States market strategy struggled to schedule a three-day in-person meeting in Berkeley. By questioning the constraints, they substituted e-mail updates and three two-hour conference calls to complete the strategy in three weeks.
2. Specifying Objectives and Alternatives
Decision makers must distinguish fundamental objectives from means objectives and generate imaginative alternatives before evaluating them.
Fundamental and Means Objectives
You need to separate fundamental objectives, which are valued for their own sake, from means objectives, which are merely steps to achieve those ends. Asking why repeatedly like peeling an onion uncovers what truly matters. Means objectives help generate alternatives and deepen problem understanding, but only fundamental objectives should be used to evaluate and compare alternatives to avoid overweighting particular factors.
The US Environmental Protection Agency uses minimize emissions as an objective, but asking why reveals the sequence: reduce pollutant concentrations, limit exposure, and ultimately protect human health, which is the fundamental objective.
Identifying objectives is an art that can be practiced systematically through a structured five-step procedure. The procedure prevents you from taking too narrow a focus and ignoring intangible, subjective, or long-term concerns.
Mary and Bill used a two-step procedure to select a primary school for their daughter Kate, combining individual lists of educational priorities and reconciling differences on uniforms by finding underlying requirements. It took them 10 minutes to complete their joint list of primary school objectives.
You should follow these steps to specify objectives:
- Write down all the concerns you hope to address through your decision without worrying about order.
- Convert your concerns into succinct objectives using a short phrase with a verb and an object.
- Separate ends from means to establish your fundamental objectives by asking why.
- Clarify what you mean by each objective by asking what do I really mean by this.
- Test your objectives to see if their capture your interests and evaluate potential alternatives.
You often fail because you take too narrow a focus, favoring tangible short-term concerns over subjective long-term values. You spend too little time specifying objectives because you assume you already know what you want. Real desires are often buried beneath societal expectations and norms, requiring deep soul-searching.
A local school board committee drafted an agenda meeting all specified board objectives, but the board rejected it because a previously unrecognized objective emerged: avoid highly controversial topics.
Generating Better Alternatives
Alternatives represent the raw material of decision making, and a chosen alternative can be no better than the best of the lot. You frequently box yourself in by relying on habit, incrementalizing status quo choices, falling back on default options, or picking the first possible solution without thorough exploration.
A recent college graduate with a degree in marine sciences felt trapped and took a family clothing business job in the Midwest because he did not actively look for alternatives in his preferred field.
Creating a robust set of alternatives requires using objectives to guide the search, challenging constraints, and doing independent thinking first. Real constraints are physical barriers that require creative workarounds, whereas assumed constraints are mental barriers imposed by habit or tradition that should be temporarily ignored during brainstorming.
A utility company assumed its proposed power plant had to be on a waterway, resulting in high costs and environmental damage. Removing this waterway constraint allowed them to find an inland site requiring a 12-mile water pump, saving 300 million dollars. The initial estimated cost of the utility plant when constrained to a waterway was 1.5 billion dollars, while the final cost of the facility after removing the waterway constraint was 1.2 billion dollars.
You can use these steps to generate better alternatives:
- Use your objectives and ask how can I achieve the objectives I've set.
- Challenge real and assumed constraints by assuming a constraint doesn't exist and creating alternatives.
- Set high aspirations to force thinking in entirely new ways rather than tweaking the status quo.
- Do your own thinking first before consulting others to avoid suppressing original ideas.
- Learn from history and experience without limiting alternatives to those previously considered.
- Ask others for suggestions after thinking carefully on your own.
- Give your subconscious time to operate by starting early and taking breaks.
- Create alternatives first and evaluate them later without slowing creativity.
Specific categories of alternatives—process, win-win, information-gathering, and time-buying—are well suited to address particular decision problems. Process alternatives use fairness mechanisms like coin tosses or voting for conflicting interests. Win-win alternatives align someone else's decision problem with your own objectives. Information-gathering alternatives reduce uncertainty, while time-buying alternatives defer full commitment to buy time for analysis.
An engineer at a Harvard Business School top tier who was contractually obligated to return to a rigid chemical company approached them with an alternative to repay tuition while pursuing management consulting, eventually leading the company to offer a better position and release him gracefully. 25 years later, the former Harvard student had become head of European operations for a major international consulting firm.
You can tailor alternatives to problems with these actions:
- List all basic alternatives and determine the right process mechanism like a secret ballot for process alternatives.
- Analyze another decision maker's objectives to create a win-win alternative that benefits both parties.
- List areas of uncertainty and identify possible ways to collect needed information for information-gathering alternatives.
- Question deadlines and evaluate pros and cons of waiting when considering time-buying alternatives.
3. Describing Consequences and Making Tradeoffs
Laying Out Consequences
You need to know how each alternative affects your objectives before you can choose. Describing consequences accurately requires shifting mindset to the future, using free-form descriptions, eliminating inferior options, and building a structured table.
Structured consequences tables and the even swap method allow decision makers to eliminate inferior options and resolve difficult tradeoffs.
Vincent Sahid used a consequences table to compare five different job offers against his objectives of pay, benefits, vacation, work enjoyment, and flexibility. When remodeling a house, imagining a typical weekday, weekend, winter day, or time with house guests helps uncover a decision's true long-term significance.
You can follow these steps to build your table:
- Mentally put yourself into the future as if you have already chosen an alternative.
- Create a free-form description of the consequences of each alternative using words, numbers, and graphics.
- Eliminate any clearly inferior alternatives by comparing them in pairs.
- Organize descriptions of remaining alternatives into a consequences table.
The Even Swap Method
Tradeoffs become difficult when you must give up something you value to gain something else. Alan Miller found that the Lombard office dominated his current Pierpoint site because it outranked Pierpoint on four objectives and tied on the fifth.
The even swap method allows decision makers to eliminate objectives by artificially balancing consequences, rendering an objective irrelevant.
A Brazilian cola company evaluated franchising versus not franchising by assessing that a 15 million dollar drop in profit could be compensated for by a 3 percent increase in market share. In that case, the company had a current market share of 20 percent and earnings of 20 million dollars in the past fiscal year. Projected profits if franchising were 10 million dollars with a 26 percent market share, while not franchising yielded 25 million dollars in profits and a 21 percent market share.
You can apply the even swap process with these actions:
- Determine the change necessary to cancel out an objective.
- Assess what change in another objective would compensate for the needed change.
- Make the even swap in the consequences table.
- Cancel out the now-irrelevant objective.
- Eliminate the dominated alternative.
4. Handling Uncertainty and Risk Profiles
Many people mistakenly judge decisions by how things turn out. A sound process can lead to a bad consequence due to bad luck, while a terrible decision process can accidentally result in a good consequence.
Decisions under uncertainty must be evaluated based on the quality of the decision-making process rather than the final outcome.
Lee Huang carefully weighed risks to build a home addition in December based on normal weather, but suffered the worst winter in 40 years, costing $6,000 extra. Roberta Giles invested without research based on a tip, but unexpectedly made four times her money when a business moved nearby.
Evaluating Uncertainty
Uncertainty adds complexity, but a risk profile captures essential information by defining key uncertainties, possible outcomes, their chances, and consequences. To build an effective risk profile, you must list all potential uncertainties and winnow them down to the few that actually influence consequences.
- What are the key uncertainties.
- What are the possible outcomes of these uncertainties.
- What are the chances of occurrence of each possible outcome.
- What are the consequences of each outcome.
Janet Ellingwood evaluated a company party and found that attendance numbers and costs would not vary enough to change her choice, leaving weather as the only key uncertainty. When an uncertainty involves a large range of potential outcomes, simplify them into ranges or categories. These categories must be mutually exclusive, collectively exhaustive, and unambiguously defined.
Expressing chances quantitatively as probabilities rather than vague qualitative terms reduces miscommunication and sharpens decisions. You can use several methods to assign these chances:
- Use your judgment.
- Consult existing information.
- Collect new data.
- Ask experts.
- Break uncertainties into their components.
Janet Ellingwood consulted a local meteorologist who judged the chance of rain during her summer party to be 30 percent.
Using Decision Trees
A decision tree provides a graphical blueprint that maps out the interrelationships among choices, uncertainties, outcomes, and consequences. Jane Stewart helped Karen Plavonic map out a personal injury lawsuit decision tree containing branches for settling versus going to court, winning or losing, and potential jury award intervals.
The even swap method can convert intangible costs and psychological impacts into monetary values to calculate overall outcome values. Karen worked with Jane and her lawyer Sam Barnes to break an $800,000 jury award range into four equally likely intervals with representative amounts.
5. Managing Risk Tolerance
A person's risk tolerance reflects their willingness to take risks to achieve better consequences, driven primarily by how heavily they weigh potential downsides against potential upsides.
Most people are risk averse, meaning poorer consequences weigh more heavily in their minds than better ones. Risk tolerance depends on the desirability of potential outcomes relative to one another and the probability of those outcomes occurring.
Robert Goldman faced a 90 percent chance of successful cataract surgery restoring 20/30 vision and a 10 percent chance of failure eroding vision to 20/100, which made his decision hinge entirely on his personal attitude toward the risk of losing his driving ability. His corrected vision was 20/50 before surgery.
You can handle such decisions by following these steps:
- Think hard about the relative desirability of the consequences of the alternatives you are considering.
- Balance the desirability of the consequences with their chances of occurring.
- Choose the most attractive alternative.
Desirability Scoring
When qualitative comparison of risk profiles is insufficient to make a decision, decision-makers can use quantitative desirability scoring to evaluate options precisely.
Quantitative analysis involves ranking consequences from best to worst and assigning scores. You can calculate each outcome's contribution by multiplying its probability by its desirability score, then sum them for an overall score.
Marisa Reyes used desirability scoring to choose between a job at an accounting firm and a consulting firm by assigning 100 to London, 80 to New York, 50 to Buenos Aires, and 0 to Santiago. This yielded a 72 overall desirability score for her accounting firm alternative and a 62.5 overall desirability score for her consulting firm alternative.
Follow these steps for precise evaluation:
- Assign desirability scores to all consequences by ranking them from best to worst, giving 100 to the best and 0 to the worst.
- Calculate each consequence's contribution to overall desirability by multiplying the outcome probability by its desirability score.
- Calculate each alternative's overall desirability score by adding the individual consequence contributions.
- Compare the overall desirability scores associated with the alternatives and choose the highest.
Desirability curves serve as a scoring shortcut when evaluating decisions with numerous possible consequences expressed through a single numerical variable. By plotting desirability scores of a few representative consequences on a graph and connecting them into a curve, you can easily determine the scores for all other possible consequences.
Jim Nance evaluated a $10,000 investment in a private venture yielding between $18,750 and $6,250 compared to a safe certificate of deposit paying 6 percent by constructing a desirability curve for money. His private-venture investment achieved a 68.35 overall desirability score, while the sure return from a certificate of deposit yielded $10,600.
The geometric shape of a desirability curve indicates your overall risk tolerance and attitude toward gains and losses. An upwardly bowed curve indicates a risk-averse attitude, where greater curvature signifies higher risk aversion. A straight line represents a risk-neutral attitude, and a downwardly bowed curve denotes a risk-seeking attitude. Jim Nance's curve showed that avoiding the largest possible loss outweighed obtaining the maximum gain, proving his risk-averse nature.
Managing Risk
When a risk exceeds your comfort level, various risk management techniques can reshape the original risk profile to make it acceptable.
Harry Healy managed the enormous risks of drilling shallow natural gas wells near Zanesville, Ohio, by sharing costs with investors, paying for seismic tests to reduce uncertainty, diversifying his assets, selling gas via fixed-price contracts, and buying insurance. Drilling a natural gas well cost $125,000, while natural gas prices experienced a 300 percent potential fluctuation in a single year. Harry kept 20 percent of a well with a $25,000 personal investment out of his $750,000 net worth, and paid $12,000 for a seismic test.
You can reshape risks using these methods:
- Share the risk with others by involving partners who take a proportional share of costs and earnings.
- Seek risk-reducing information to temper uncertainty and study borderline sites.
- Diversify the risk by avoiding placing all assets into a single basket.
- Hedge the risk by utilizing market contracts or fixed-price agreements to manage price fluctuations.
- Insure against risk whenever a risk consists of a significant but rare downside with no upside.
6. Navigating Linked Decisions
Linked decisions occur when a current choice directly influences future choices, creating a sequence of decisions and learning. Unlike standard decisions whose outcomes simply affect the future, linked decisions create a necessary connection where the alternative selected today shapes the available alternatives tomorrow and their relative desirability. The typical pattern follows a decide-learn sequence.
A juice company marketing director choosing between a thirst quencher or an energy drink concept must consider future options like product reformulation if initial sales are low.
Analyzing complex linked decisions requires a structured six-step process that simplifies options by focusing on critical uncertainties and future consequences.
Linked decisions create a necessary connection where the alternative selected today shapes the available alternatives tomorrow.
The process reduces thousands of combinations by isolating key uncertainties, identifying information-gathering strategies and future linked decisions, mapping them on a decision tree, and working backward from the end points to solve the basic decision.
- Step 1: Understand the basic decision problem by defining the problem, specifying objectives, generating alternatives, and selecting the few critical uncertainties that most influence consequences.
- Step 2: Identify ways to reduce critical uncertainties by listing information that would help, determining how it changes your view, and deciding how to obtain it.
- Step 3: Identify future decisions linked to the basic decision by asking what follows naturally from each alternative, keeping the time horizon short.
- Step 4: Understand relationships in linked decisions by constructing a timeline and a decision tree to sequence choices, information, and consequences.
- Step 5: Decide what to do in the basic decision by working backward from the right side of the decision tree and estimating costs and benefits of information gathering.
- Step 6: Treat later decisions as new decision problems when you actually reach subsequent points, taking advantage of new knowledge and passage of time.
Analyzing Linked Choices
Information-gathering alternatives should only be pursued if the cost of obtaining the information is lower than its value in changing the decision. New information is only beneficial if it alters your chosen path. If you would make the exact same basic decision regardless of what you learn, the information is not worth gathering.
- List the kinds of information that could reduce your critical uncertainties.
- Determine how your view of the decision might change if you encountered that new information.
- Estimate the costs and benefits of gathering the information, factoring in money, effort, time, discomfort, and delay.
- Ask what you would pay to completely resolve the uncertainty; if gathering the information costs more, discard the alternative.
Dan Morgan, a 52-year-old software salesperson at a struggling company named Omega Software, must decide whether to stay or accept an offer from DotCom Communications in Amherst, Massachusetts, 100 miles away. Dan and Doris evaluated staying in Arlington versus moving, and even devised an Explore alternative involving a six-month unpaid leave from Omega to trial the DotCom job.
Flexible Planning
When environmental uncertainty is too high to plan future decisions with confidence, decision makers should use flexible plans to keep options open. Flexible plans help individuals and organizations adapt to fast-developing, volatile situations without locking themselves into rigid long-term paths.
A computer manufacturer purchasing 90 percent of its chips from a regular supplier and 5 percent from each of two new sources to guard against supply interruptions.
- Develop all-weather plans as compromise strategies that work well across most situations when the risk of outright failure is high.
- Use short-cycle plans by making an initial choice and reassessing it frequently, such as updating a one-year business plan quarterly.
- Act as option wideners to implement choices that expand your set of future alternatives.
- Create be prepared plans that act as backup preparedness responses for most contingencies.
7. Avoiding Psychological Traps
In addition to process errors, decisions are heavily undermined by invisible psychological traps that arise from mental heuristics and biases hard-wired into human thinking. While heuristic routines help people cope with daily complexity, they can distort judgment and lead to errors. Because these traps are invisible and ingrained, awareness and deliberate counter-disciplines are required to avoid falling into them.
Using the clarity heuristic to judge distance by how clearly an object appears can cause errors on hazy days, creating a distortion that is minor for most people but potentially catastrophic for an airline pilot.
The anchoring trap occurs when the mind gives disproportionate weight to the first piece of information received, using initial ideas or estimates as an anchor for subsequent thoughts.
Anchors establish the terms of a decision and can skew forecasts, negotiations, and estimates. When researchers asked groups whether the population of Turkey was greater than 35 million before asking for their population estimate, answers increased significantly compared to groups first asked using a 100 million figure.
- Always view a decision problem from different perspectives by using alternative starting points.
- Think about the decision problem on your own before consulting others to avoid becoming anchored.
- Seek information and opinions from a variety of people to widen your frame of reference.
- Be careful to avoid anchoring other people by telling them as little as possible about your own tentative decisions.
- Prepare well before negotiating to be less susceptible to anchoring tactics.
Decision makers display a strong bias toward alternatives that perpetuate the current situation, finding comfort in inaction even when better alternatives exist. The magnetic attraction of the status quo grows stronger when multiple alternatives are available because choosing between them requires more mental effort.
In an experiment where people were randomly given either a decorated mug or a large Swiss chocolate bar and told they could easily exchange gifts, only one in ten actually made the trade.
- Always remind yourself of your objectives and examine how they would be served by the status quo.
- Never think of the status quo as your only alternative.
- Ask yourself whether you would choose the status quo alternative if it weren't actually the status quo.
- Avoid exaggerating the effort or cost involved in switching from the status quo.
- Put the status quo to a rigorous test instead of simply comparing how it is with how other alternatives would be.
- If several alternatives are clearly superior to the status quo, force yourself to choose one rather than defaulting.
The sunk-cost trap leads people to justify past, unrecoverable investments of time or money, making choices based on avoiding loss rather than on present economic realities. Fifteen years ago, the authors helped a major U.S. bank recover from foreign bad loans. Bankers who originated problem loans were far more likely to throw good money after bad by advancing additional funds than new bankers taking over the accounts.
- Seek out and listen carefully to the views and arguments of people who weren't involved with earlier decisions.
- Examine why admitting to an earlier mistake distresses you and deal with your wounded self-esteem head-on.
- If you worry about being second-guessed by others, make this consequence an explicit part of your decision process.
- If you fear sunk-cost biases in subordinates, pick someone previously uninvolved to make the new decision.
The confirming-evidence trap drives individuals to seek out information supporting their existing point of view while avoiding and dismissing contradictory evidence. In a study where groups supporting and opposing capital punishment read two reports concluding opposite findings on its effectiveness, members of both groups became even more convinced of their original position.
- Get someone you respect to play devil's advocate or build the counterarguments yourself.
- Be honest with yourself about your motives for gathering information.
- Expose yourself to conflicting information and examine all evidence with equal rigor.
- In seeking advice, avoid asking leading questions that invite confirming evidence.
Wise Decision Making
The framing trap distorts decision making because the way a problem or question is posed influences choices by making different objectives and reference points salient. Neighboring states New Jersey and Pennsylvania altered auto insurance laws to offer a cheaper premium with a limited right to sue. New Jersey framed it as automatic limited rights unless specified otherwise, whereas Pennsylvania framed it as automatic full rights, costing Pennsylvania $200 million in savings.
- Remind yourself of your fundamental objectives and make sure your frame advances them.
- Don't automatically accept the initial frame; always try to reframe the problem in different ways.
- Try posing problems in a neutral, redundant way that combines gains and losses or embraces different reference points.
- Ask yourself how your thinking might change if the framing changed near the end of the process.
- When subordinates recommend decisions, challenge the way they framed the problem.
Decision makers frequently suffer from overconfidence, overweight dramatic events through recallability, and neglect statistical base rates. MIT researchers calculated the actual probability of a fatal jet crash on a major U.S. airline to be about one in 10,000,000, which is vastly underestimated or overestimated by the public due to media attention.
- Consider extreme values first when making forecasts to avoid overconfidence anchoring.
- Actively challenge your own or advisors' extreme figures by imagining alternative circumstances.
- Examine assumptions against memorability distortions and rely on statistics rather than unaided memory.
- Explicitly consider base rates and avoid mixing up conditional probability statements.
Excessive caution, misinterpreting random phenomena as patterns, and treating coincidence as mystical occurrences distort probability and decision quality. An automotive manufacturer experienced severe surplus and deep price cuts because multiple departments independently slanted their sales forecasts just to be safe, cascading into heavily inflated production numbers.
- State probabilities and estimates honestly without adjustments for prudence.
- Document information and reasoning so others understand your estimates.
- Do not try to outguess purely random phenomena or test trading systems with real money.
- Remember that the world presents many potential surprises and rare events are bound to occur by chance.
