Decision-Making Techniques and Models in Management

Updated 10 October 2026 · Fact-checked

Decision-making models describe how managers choose: the rational model seeks the best option with full information, bounded rationality accepts a satisfactory option, and the intuitive model relies on experience. Techniques such as decision trees, brainstorming and the Delphi technique support choices. Match each name to its core idea to answer MCQs.

Understand Decision-Making Techniques and Models

A decision-making model explains how a manager moves from a problem to a choice. A technique is a tool that helps you generate ideas or evaluate options. The exam tests whether you can tell them apart and match each one to its key feature.

The rational model assumes the manager knows the problem clearly, can list all alternatives, knows the outcome of each, and picks the one that maximises results. It is an ideal. Real managers rarely have all this information or time.

Bounded rationality, associated with Herbert Simon, says a manager's rationality is limited by incomplete information, limited time and limited mental capacity. So the manager does not search for the best option. They pick the first option that is good enough. This is called satisficing. The intuitive model relies on gut feeling, experience and judgement built over years. It works well when time is short or data is thin, but it is hard to explain or defend.

A decision tree is a diagram that shows choices as branches. It has decision points, chance events with probabilities, and payoffs. You work out the expected value of each branch and choose the best. It suits decisions made under risk, where probabilities are known.

Group techniques bring many minds together. In brainstorming, a group meets and produces as many ideas as possible, and criticism is not allowed during idea generation. Evaluation comes later. In the Delphi technique, a panel of experts answers questionnaires in several rounds without meeting. A coordinator summarises the answers and sends them back until opinions converge. Experts stay anonymous, so no one dominates.

Key formulas to remember

Expected value at a chance node: EV = Σ (probability × payoff); Probabilities at one chance node must add up to 1. Use net payoff if a cost is involved.
Decision tree rule: Choose the branch with the highest expected value (net of cost); If the payoffs are costs, choose the lowest expected cost instead.
Rational model vs bounded rationality: Rational = optimising (best option); Bounded = satisficing (good enough option); This contrast is the most common MCQ pair.
Brainstorming vs Delphi: Brainstorming = face-to-face, ideas, no criticism; Delphi = experts, remote, anonymous, repeated rounds; Use the meeting and anonymity cues to separate them.

How to solve Decision-Making Techniques and Models questions

Most questions on this topic are definition or matching MCQs, with an occasional decision tree calculation. Use this method.

1Read the question stem and underline the clue words, such as best, good enough, gut feeling, experts, anonymous, probability.
2Decide whether the question asks about a model (how a choice is made) or a technique (a tool used).
3Match the clue to the right name: best option means rational, good enough means bounded rationality, experience means intuitive.
4For group questions, check whether people meet face to face. Meeting and free ideas mean brainstorming. Anonymous experts and rounds mean Delphi.
5For a decision tree, work backwards: compute the expected value at each chance node, then subtract any cost.
6Compare the net values of the branches and pick the highest.
7Eliminate options that mix features, for example a Delphi option mentioning a face-to-face meeting.

Quickest way: Clue-word matching

When to use it: Use it for any definition or comparison MCQ. It takes about 20 seconds per question.

Spot the clue word in the stem.
Recall the one-line link: optimise = rational, satisfice = bounded, gut = intuitive, branches = tree, free ideas = brainstorming, anonymous experts = Delphi.
Strike out options that contradict the link.
For tree sums, calculate expected values only for the branches still in contention.

Common mistakes in Decision-Making Techniques and Models

Treating bounded rationality as irrational decision-making.
The word bounded sounds like a flaw in the manager.
Fix: Remember that the manager is still rational, but within limits of information, time and ability. The result is a satisfactory choice.
Mixing up brainstorming and the Delphi technique.
Both are group techniques for gathering ideas or opinions.
Fix: Brainstorming is a live meeting with free ideas. Delphi uses anonymous experts who never meet and answer in rounds.
Allowing criticism during brainstorming.
Students assume a group discussion should judge ideas immediately.
Fix: Criticism is held back during idea generation. Ideas are evaluated afterwards.
Forgetting to subtract the cost in a decision tree.
Students stop once they find the expected payoff.
Fix: Compute net value = expected payoff − cost of that option, then compare.
Calling the rational model realistic.
It is the first model taught, so it seems the standard in practice.
Fix: It is a normative ideal that assumes complete information. Bounded rationality describes real behaviour better.

Worked examples

Example 1

A firm launches a new product. Success has probability 0.6 and gives a profit of ₹10,00,000. Failure has probability 0.4 and gives a loss of ₹2,00,000. What is the expected value of launching, and should the firm launch if not launching gives ₹0?

Show the solution

Expected value = 0.6 × 10,00,000 + 0.4 × (−2,00,000).
0.6 × 10,00,000 = ₹6,00,000.
0.4 × (−2,00,000) = −₹80,000.
EV = 6,00,000 − 80,000 = ₹5,20,000.
Not launching gives ₹0, and 5,20,000 is higher.

Answer: The expected value of launching is ₹5,20,000, so the firm should launch.

Example 2

Which technique involves a panel of experts who give opinions anonymously over several rounds of questionnaires? (a) Brainstorming (b) Delphi technique (c) Intuitive model (d) Satisficing

Show the solution

Clue words: panel of experts, anonymously, several rounds.
Brainstorming is a live meeting, so (a) is out.
The intuitive model is an individual gut-based approach, so (c) is out.
Satisficing means accepting a good enough option, not a group technique, so (d) is out.
The Delphi technique fits all the clues.

Answer: (b) Delphi technique

Exam tips

Learn the one-line contrast for each pair: rational vs bounded, brainstorming vs Delphi.
Watch for words like best, optimal, satisfactory and good enough, because they point directly to the model.
In decision tree sums, keep the numbers simple and always check that the probabilities add up to 1.
There is no negative marking, so attempt every question, and use elimination when unsure.
Read all four options. Examiners often include a statement with one wrong feature attached.

Decision-Making Techniques and Models: frequently asked questions

What is the difference between brainstorming and the Delphi technique?

Brainstorming is a face-to-face group session to produce many ideas, with criticism held back. The Delphi technique collects opinions from anonymous experts through repeated questionnaires without a meeting. Delphi avoids dominance by senior people.

What is the difference between the rational model and bounded rationality?

The rational model assumes complete information and picks the best option. Bounded rationality accepts that information, time and ability are limited, so the manager picks a satisfactory option. This is called satisficing.

What is a decision tree in management?

It is a diagram that maps choices, chance events, probabilities and payoffs as branches. You calculate the expected value of each branch and choose the best one. It is mainly used when outcomes are uncertain but probabilities can be estimated.

Which techniques are used for group decision making?

Common ones are brainstorming and the Delphi technique. Both pool the views of many people, but they differ in whether participants meet and whether they stay anonymous.
