Question
Question 2 (b) · 9 marksWhat is meant by Bounded Rationality in decision-making? Explain in what way it differs from Perfect Rationality in managerial decisions.
Reworded from the university paper; the task is the same. The original paper belongs to the University of Delhi. See DU's question bank.

What the paper leaves open
The cover prints the course as B.Com. (Hons) CBCS with maximum marks 75. This is read as a misprint: the paper carries the UGCF code for this course (2412081101) and five questions of 18 marks each (90), so it is treated as the December 2025 UGCF paper.

Perfect (complete) rationality
The classical, or economic, model of decision making assumes that the decision maker is perfectly rational. Such a person:
1Files to the ceiling, a queue at the door: no manager can read every option.
Complete rationalityThe decision maker has clear goals, knows all alternatives and their consequences.
2The clock is running, so he shakes hands with the first candidate who clears the bar.
SatisficingChoose the first one that meets their minimum acceptable standards.
- has a clear, single objective and knows it fully;
- knows every possible alternative;
- knows the consequences of each alternative with certainty;
- can rank all alternatives consistently; and
- always chooses the one that gives the maximum result.
The decision maker is thus an economic man who maximises: the alternative chosen is the one that gives the greatest result in the given conditions. The model is useful as a logical standard, but real decisions rarely meet its conditions.
Herbert Simon argued that human rationality is bounded, or limited. Managers try to be rational, but their rationality is limited by incomplete information, limited time, and the limited capacity of the human mind to process information. As a result they do not search for the best possible solution; they search until they find one that is good enough to meet their minimum standards, and they accept it. Simon called this satisficing (a blend of satisfy and suffice), and the decision maker an administrative man.
- Incomplete information: not all alternatives or consequences can be known.
- Limited time and cost: searching further takes time and money.
- Cognitive limits: people cannot process every factor at once.
- Uncertainty: the future is unknown, so outcomes cannot be predicted exactly.
- Conflicting goals: organisations pursue several goals at once.
- Personal values, biases and emotions affect judgement.
- Organisational constraints: policies, politics and past commitments limit choice.
Differences between bounded and perfect rationality
| Basis | Perfect rationality | Bounded rationality |
|---|---|---|
| Model of the decision maker | Economic man | Administrative man |
| Information | Complete | Incomplete |
| Alternatives | All known and evaluated | Only some identified and evaluated |
| Consequences | Known with certainty | Uncertain |
| Goal | Clear and single | Multiple, sometimes vague |
| Decision rule | Maximising: choose the best | Satisficing: choose the first acceptable |
| Time and cost of search | Ignored | Limit the search |
| Realism | Normative ideal | Describes actual behaviour |
| Influence of values and politics | Ignored | Recognised |
Example. A company looking for a new warehouse cannot inspect every building in the region. It sets conditions, size, rent limit, highway access, and leases the first building that satisfies them. Under perfect rationality it would compare all buildings and choose the best.
Perfect rationality describes how decisions should be made in ideal conditions; bounded rationality describes how they are made. Managers can widen the bounds through better information systems, decision tools, group decision making and experience, but cannot remove them altogether. Recognising the bounds also guards against overconfidence: a manager who knows a decision rests on partial information will review it as new facts arrive.
