Management Decision Making Management decision making is a complex mix of
knowledge, experience, creative thinking, and risk taking. It is often a rapid-fire, fragmented process
More and more companies are pushing critical decision making down to the level of the organization most affected by the decision
A decision can be defined as a conscious choice among alternatives followed by action to implement the decision
Decision-making process is a series of steps that is followed, either consciously or unconsciously, to make a choice and undertake action

Management Decision Making (cont.)
Managers must learn how to deal with a decision-making environment that emphasizes communicating, working with others, and working with incomplete information
Decisions are often based on impressions, estimates, and personal experience
Management researchers have developed a set of useful concepts to understand the phenomenon
Individual decision making differs from group decision making

Types of Managerial Decisions
Programmed and Non-Programmed Decisions
Proactive and Reactive Decisions
Intuitive and Systematic Decisions

6/42
Programmed and Non-Programmed Decisions Programmed Decisions
One that would be made if a particular situation occurs and a routine procedure or policy has been established to handle it
Repetitive and routine A large number in daily operations Although they should be made with care and
concern about effectiveness, they should be made efficiently without needlessly tying up organizational resources

Programmed and Non-Programmed Decisions (cont.)
Non-Programmed Decisions No pre-existing structure or decision-
making procedure in place Have significant implications for the future
of the organization and must be made only after careful analysis

Proactive and Reactive Decisions
Proactive Decision Made in anticipation of an external change
or other conditions Can prevent many common problems
Reactive Decision Made in response to changes that have
already occurred

Intuitive and Systematic Decisions Intuitive Decision Making
Use of estimates, guesses, or hunches to decide among alternative courses of action
“Voice of experience” that speaks to managers when faced with a decision situation
Don’t rely on intuition alone; supplement intuition with systematic information gathering and analysis
Systematic Decision Making Organized, exacting, data-driven process Requires a clear set of objectives, a relevant
information base, and a sharing of ideas among key managers and other employees

The Decision-Making Process
Clarify the problem or opportunity
Develop alternative courses of action
Evaluate and select a course of action
Implement the decision
Monitor its effectiveness
Copyright Atomic Dog Publishing, 2003
12/42
Step 1: Clarify the Problem or Opportunity
Problems are defined as the realization that a discrepancy exists between a desired state and current reality
Several common biases or mistakes managers make when identifying and clarifying a problem: Perceptual inaccuracies Defining problems in terms of solutions Identifying symptoms as problems
Consider an issue from a variety of perspectives
Consult various perspectives before making decisions

Step 2: Develop Alternative Courses of Action
Examine the organization’s internal and external environments for information and ideas that may lead to creative solutions to a problem
A popular approach to this is known as benchmarking (identify and study firms who are leaders in a given area of business)
Managers should encourage creativity and innovation among employees
Encourage a diversity of approaches to problem solving can lead to better solutions and courses of action

14/42
Step 3: Evaluate Alternatives and Select a Course of Action Select the alternatives that will produce the most
favorable outcomes and the least unfavorable outcomes
Two cautions should be kept in mind Keep this step distinct from the previous step—especially in a
group context Be wary of solutions that are evaluated as being “perfect”
Rather than being an optimizer, the decision maker is said to be a “satisficer” —a person who accepts a reasonable alternative course of action that isn’t necessarily the optimum course of action

15/42
Step 4: Implement the Selected Alternative Course of Action A decision is an abstraction if it isn’t implemented
Actions must be implemented effectively if it is to achieve an objective
Implementing decisions involves delegating responsibilities to people
Here are six steps to effective delegation: Define the task clearly Give guidelines to begin to follow Give authority to accomplish the task Monitor the tasks, but don’t hover Give feedback along the way Reward and recognize effort as well as results
Copyright Atomic Dog Publishing, 2003
16/42
Step 5: Control and Assess the Consequences of the Action
Periodic assessment of the results of the chosen course of action
If actual results aren’t meeting planned results, changes must be made
Two types of feedback that managers use to gather the necessary information: Formative Summative

Influences on Individual Decision Making
Copyright Atomic Dog Publishing, 2003
18/42
Influences on Individual Decision Making
Importance of the decision
Time pressures
Manager’s values
Manager’s propensity for risk
Copyright Atomic Dog Publishing, 2003
19/42
The Importance of the Decision
Numerous yardsticks for measuring the importance of a decision exist, including the amount of resources involved, the number of people influenced by the decision, and the time required to make the decision
Managers must allot more time and attention to significant problems
Copyright Atomic Dog Publishing, 2003
20/42
Time Pressures
Managers must make the most of their decisions in others’ time frames
When time pressures are significant, managers may be unable to gather enough information
Time management is a priority
Managers who effectively manage their time feel less stress and tend to make better decisions than their stress-filled counterparts
Copyright Atomic Dog Publishing, 2003
21/42
The Manager’s Values An individual’s values become guidelines when s/he
confronts a choice
Values are one of the most important influences on human behavior
Values are the likes, dislikes, shoulds, oughts, judgments, and prejudices that determine how the world is viewed
Value-based decision making is methodical and ensures that organizational values enter into all major decisions
Although people don’t think consciously about their values and rarely arrange them in any kind of order, managers should be very aware of their values
Serious conflicts can occur among values

22/42
The Manager’s Propensity for Risk
People vary greatly in their propensity to take risks
The issue for managers is not whether to take risks, but how to take reasonable risks
Copyright Atomic Dog Publishing, 2003
Group Decision Making
Copyright Atomic Dog Publishing, 2003
24/42
Group Decision Making
A great deal of decision making is achieved through committees, teams, task forces, “virtual teams,” etc.
Decisions made on non-programmed problems being made by one individual on a regular basis are unusual
Use of the collective approach to a decision-making process is increasing
Many managers spend as much as 80% of their working time in committee meetings

Individual vs. Group Decision Making
Groups usually take more time to reach a decision
Consensus decisions with five or more participants are superior to individual decision making, majority vote, and leader decisions
Problems with group decision making: Pressure to conform Influence of a dominant personality Status incongruity Attempt of certain participants to influence others
Copyright Atomic Dog Publishing, 2003
26/42
Individual vs. Group Decision Making (cont.)
Non-programmed decisions appear to be better suited to group decision making
As we move from “individual” to “consensus,” the quality of the decision improves
For a complex problem requiring pooled knowledge, the quality of the decision is likely to be higher as the group moves toward achieving consensus

Creativity in Group Decision Making
If groups are better suited to non-programmed decisions than individuals, then it is important that an atmosphere fostering group creativity be created

Techniques for Stimulating Creativity
Brainstorming
The Delphi Technique
The Nominal Group Technique
Copyright Atomic Dog Publishing, 2003
29/42
Brainstorming
Brainstorming promotes the generation of ideas while at the same time avoiding the inhibitions many people feel in group settings
The basic rules are: No idea is too ridiculous Each idea presented belongs to the group, not to
the person stating it No idea can be criticized
Copyright Atomic Dog Publishing, 2003
30/42
The Delphi Technique
The Delphi technique comprises the solicitation and comparison of anonymous judgments on the topic of interest through a set of sequential questionnaires that are interspersed with summarized information and feedback of opinions from earlier responses
Copyright Atomic Dog Publishing, 2003
31/42
The Delphi Technique (cont.) The advantage is having several judges while
removing the biasing effects that might occur during face-to-face interaction Basic approach is to collect anonymous judgments
from group members by mail questionnaire A process administrator then summarizes the
responses as the group consensus, and feeds this summary back along with a second questionnaire for reassessment
Respondents independently evaluate their earlier responses
Underlying belief is that the consensus estimate will result in a better decision after several rounds of anonymous group judgment
Copyright Atomic Dog Publishing, 2003
32/42
The Nominal Group Technique (NGT)
The NGT comprises processes that bring people together but do not allow them to communicate verbally. Thus, the collection of people is a group “nominally,” or “in name only”
Copyright Atomic Dog Publishing, 2003
33/42
The Nominal Group Technique (NGT) (cont.) A structured group meeting proceeds as
follows: A group of individuals (7 to 10) sit around a table
but do not speak to one another Each person writes ideas on a pad of paper A recorder writes the ideas on a flip chart in full
view of the entire group This continues until all of the participants indicate
that they have no further ideas to share Each idea receives attention before a vote is taken Each participant, in private, selects priorities by
ranking or voting The group decision is the mathematically pooled
outcome of the individual votes

Information Technology and Decision Making In decision-making situations, managers can’t
possibly use “all available information”
The challenge for managers is to collect, process, and warehouse the most relevant information to make effective decisions in the present and future
Tools for warehousing and retrieving information for use throughout their firms: Data warehousing Data mining Data marts Search engines Software agents

Attributes of Useful Information
Accessible
Timely relevant
Accurate
Verifiable
Complete
Clear

Information Sharing
Organizations that train people in the value of information and how to use it and share it gain competitive advantage over those who don’t
Copyright Atomic Dog Publishing, 2003
Decision Support Systems (DDS)
Copyright Atomic Dog Publishing, 2003
39/42
Decision Support Systems (DDS)
DDS is an interactive information system that enables managers to gain instant access to information in a less structured format than a traditional management information system or database
Must obtain information about the firm, competitors, and the business environment
May include links to the World Wide Web, and have built-in artificial intelligence that adjusts to group behaviors and needs
DDS is inherently user friendly
Copyright Atomic Dog Publishing, 2003
40/42
Decision Support Systems (cont.)
Supports managerial skills at all levels of decision making by providing instant response to managers’ information needs
An executive information system (EIS) is a user-friendly DDS designed specifically for executives
Consolidate the analysis provided by a DDS, interpret it considering the firm’s strategic goals, and present the results of executives in an easily understandable format

Expert Systems and Artificial Intelligence
Artificial intelligence allows computers to solve problems involving imagination, abstract reasoning, and common sense
Expert systems refers to computer systems that can make decisions without human interaction, by imitating human thinking and offer advice or solutions to complex problems in much the same way as a human expert would
