DECISION MAKING
Decision
Making a choice from two or more alternatives.
6–2
HOW ARE DECISIONS MADE IN ORGANIZATIONS? Decision environments include: CERTAIN ENVIRONMENTS. RISK ENVIRONMENTS. UNCERTAIN ENVIRONMENTS.
6–3
Certain environments. environments Exist when information is sufficient to predict
the results of each alternative in advance of implementation. Certainty is the ideal problem solving and
decision making environment.
Risk environments. environments Exist when decision makers lack complete certainty regarding the outcomes of various courses of action, but they can assign probabilities of occurrence. Probabilities can be assigned through objective statistical procedures or personal intuition. 6–4
Uncertain environments. Exist when managers have so little information that they cannot even assign probabilities to various alternatives and possible outcomes. Uncertainty forces decision makers to rely on individual and group creativity to succeed in problem solving. Also characterized by rapidly changing: External conditions. Information technology requirements. Personnel influencing problem and
definitions.

STEP 2: IDENTIFYING DECISION CRITERIA Decision criteria are factors that are important (relevant) to
resolving the problem. Costs
that will be incurred (investments required) Risks likely to be encountered (chance of failure) Outcomes that are desired (growth of the firm)
Step 3: Allocating Weights to the Criteria • Decision criteria are not of equal importance: Assigning a weight to each item places the items in the correct priority order of their importance in the decision making process. 6–10

STEP 4: DEVELOPING ALTERNATIVES
Identifying viable alternatives
Alternatives are listed (without evaluation) that can resolve the problem.
STEP 5: ANALYZING ALTERNATIVES • Appraising each alternative’s strengths and weaknesses An alternative’s appraisal is based on its ability to resolve the issues identified in steps 2 and 3.
6–12
STEP 6: SELECTING AN ALTERNATIVE
Choosing the best alternative
The alternative with the highest total weight is chosen.
STEP 7: IMPLEMENTING THE DECISION • Putting the chosen alternative into action. Conveying the decision to and gaining commitment from those who will carry out the decision.

STEP 8: EVALUATING THE DECISION’S EFFECTIVENESS
The soundness of the decision is judged by its outcomes.
How effectively was the problem resolved by outcomes resulting from the chosen alternatives?
If the problem was not resolved, what went wrong?
6–16
MAKING DECISIONS
Rationality
Managers make consistent, valuemaximizing choices with specified constraints.
Assumptions makers:
are
that
decision
Are perfectly rational, fully objective, and logical.
Have carefully defined the problem and identified all viable alternatives.
Have a clear and specific goal
Will select the alternative that maximizes outcomes in the organization’s interests rather than in 6–17 their personal interests.
ASSUMPTIONS OF RATIONALITY
6–18
Managers make decisions rationally, but are limited (bounded) by their ability to process information.
Assumptions are that decision makers:
Will not seek alternatives
out
or
have
knowledge
of
all
Will satisfice—choose the first alternative satisfice encountered that satisfactorily solves the problem— rather than maximize the outcome of their decision by considering all alternatives and choosing the best. 6–19

PROBLEMS AND DECISIONS
Structured Problems
Involve goals that clear.
Are
familiar (have occurred before).
Are
easily and completely defined— information about the problem is available and complete.
Programmed
Decision
A
repetitive decision that can be handled by a routine approach. 6–23
TYPES OF PROGRAMMED DECISIONS
A
Policy
A general guideline for making a decision about a structured problem.
A Procedure A
series of interrelated steps that a manager can use to respond (applying a policy) to a structured problem.
A
Rule
An
explicit statement that limits what a manager or employee can or cannot do in carrying out the steps involved in a procedure. 6–24
Policy
Accept all customer-returned merchandise (Commodities offered for sale).
Procedure Follow
all steps for completing merchandise return documentation.
Rules Managers
$50.00.
No
must approve all refunds over
credit purchases are refunded for cash. 6–25
PROBLEMS AND DECISIONS (CONT’D) Unstructured
Problems
Problems
that are new or unusual and for which information is ambiguous or incomplete.
Problems
that
will
require
custom-made
solutions. Nonprogrammed
Decisions
Decisions
that are unique and nonrecurring.
Decisions
that generate unique responses.

DECISION-MAKING CONDITIONS
Certainty
A ideal situation in which a manager can make an accurate decision because the outcome of every alternative choice is known.
Risk A
situation in which the manager is able to estimate the likelihood (probability) of outcomes that result from the choice of particular alternatives.
6–28
Uncertainty
Limited or information prevents estimation of outcome probabilities for alternatives associated with the problem and may force managers to rely on intuition, hunches, and “gut feelings”.
Maximax: the optimistic manager’s choice to maximize the maximum payoff (income and profit)
Maximin: the pessimistic manager’s choice to maximize the minimum payoff (income and profit)
Minimax: the manager’s maximum regret (loss).

Bias
Selecting and highlighting certain aspects of a situation while ignoring other aspects.

Availability Bias Losing
decision-making objectivity by focusing on the most recent events.
Representation Bias Drawing
analogies and seeing identical situations when none exist.
Randomness Bias Creating
unfounded meaning out of random
events.
Sunk Costs Errors Forgetting
that current actions cannot influence past events and relate only to future consequences.
6–39
Self-Serving Bias Taking
quick credit for successes and blaming outside factors for failures.
Hindsight Bias Mistakenly
believing that an event could have been predicted once the actual outcome is known (after-the-fact).

Guidelines for making effective decisions: Know when it’s time to call it quits. Practice the five “whys”. Be an effective decision maker.
Habits
of highly reliable organizations (HROs)
Are
not tricked (deceived )by their success. Defer to the experts on the front line. Let unexpected circumstances provide the solution. Embrace complexity. Anticipate, but also anticipate their limits.

It focuses on what is important.
It is logical and consistent.
It acknowledges both subjective and objective thinking and blends analytical with intuitive thinking.
It requires only as much information and analysis as is necessary to resolve a particular dilemma.
It encourages and guides the gathering of relevant information and informed opinion.
It is straightforward, reliable, easy to use, and flexible. 6–43

Managers face complex choice processes. Decision making information may not be available. Bounded rationality and cognitive limitations affect the
way people define problems, identify alternatives, and choose preferred solutions. Most decision making in organizations goes beyond stepby-step rational choice. Most decision making in organizations falls somewhere between the highly rational and the highly chaotic. Decisions must be made under risk and uncertainty. Decisions must be made to solve nonroutine problems. Decisions must must be made under time pressures and information limitations. Decisions should be ethical.
