Training Decision Making in Organizations:
Dealing with Uncertainty, Complexity, and Conflict
di Scott Middleton
Abstract
Decision making is an employee skill that is critical to the success of all organizations. This paper discusses the relationship between decision making and problem solving, and details many strategies from the research literature that have been shown to enhance decision making for individuals and groups. Training these decision making aids to develop employee's decision making abilities, both individually, and in groups, is a wise investment in any organization's human resources.
Training Decision Making in Organizations Definition
Decision making has been defined as "the processes of thought and action that culminate in choice behavior"(MacCrimmon, 1973). Decision making and problem solving are interrelated topics both involving use of judgment, bridging thought and action. The research literature sometimes describes decision making as a subset of problem solving, dealing with evaluation and choice from a set of alternatives. Problem solving is seen as "the whole process of problem formation, alternative generation, and information processing which culminates in choice"(MacCrimmon & Taylor,1976, p. 1397). Other literature sees problem solving as a subset of decision making, since it deals primarily with "simple solutions that often have correct solutions, while decision making encompasses broader, more important contexts" (MacCrimmon & Taylor,1976, p. 1397). Obviously, decision making abilities of employees play a key role in the performance and success of an organization, so training that improves decision making is highly valuable investment in human resources development. This training can focus on two levels, individual decision making skills and group decision making skills. These are both critical in the modern, learning organization. Because such organizations have the goal of empowering employees by delegating decision making authority to the lowest levels, it would be wise to ensure those employees are well prepared for the task. Also, the ever-increasing use of work groups to make decisions makes the process more complex because of the social, interpersonal factors at play. So you need to educate employees on decision making strategies both on the individual and group level.
Components of the Decision Problem
Information processing theorists such as Reitman (1964) conceptualize decision
problems by a three component vector. The first component is the initial
or current state the decision maker, or the resources he/she has available.
The second is the terminal or desired state he/she would like to achieve,
the target or goal. The third are called transformations, decision alternatives,
or operators, but essentially are the processes or steps that the decision
maker must take to get from the initial condition to the desired condition.
This manner of viewing decision problems shows how they are subjective and
relative to the perceptions of the decision maker. If he/she doesn't perceive
the gap between the two conditions, he doesn't see the need to make a decision.
Even if he/she perceives the gap, he/she must be motivated to resolve it.
Also, the decision maker has to have the abilities or resources available,
or it is futile.
Well-Structured vs. Ill-Structured Decision Problems
To the extent that the decision maker is familiar with the three components
in a decision problem, it is well-structured. Well-structured decision problems
allow the decision maker to apply past experience by using transformations
that have worked for similar situations in the past. Routine decisions have
standard operating procedures (SOPs) that can be used. These standard responses
can be algorithms that are a finite number of logical steps, that like a
computer program, lead to the same output. They also can be heuristics,
or rules of thumb that are procedures or outlines for seeking solutions.
They increase effectiveness, but do not guarantee success. To the extent
to which the components are unfamiliar to the decision maker, the decision
problem is ill-structured. The decision maker will use the component he
is most familiar with as a tool to solve the problem. If he only knows the
current state, he will tend to make incremental moves, testing to see if
it is in the right direction. If he knows the desired state, he will try
to deduce backwards to derive transformations that will lead back to the
initial state. If the decision maker is familiar with a certain set of transformations,
he will try to specify the initial and final state to allow him to use what
he knows.
Conditions Constibuting to Ill-Structuredness
Typically, most critical decisions in organizations tend to
be ill-structured. Decision making strategies can be categorized by the
three environmental conditions that contribute most strongly to ill-structuredness:
uncertainty, complexity, and conflict. (MacCrimmon, 1970).
Uncertainty
The decision maker can try to take account of the uncertainty by trying
to model it. People try to cope with uncertainty by attempting to identify
patterns and fit occurrences that change in systematic ways into a model.
They can plug recent observations into formulas to make time-series forecasts.
They can also attempt to assign subjective probabilities to uncertain events.
There are various biases and various methods for assessing subjective probabilities
that can be taught to decision makers.
Alternative Generation and Testing
There also are strategies for reducing uncertainty by alternative generation
and testing. Brainstorming, a well-known technique created by Osborn (1941),
uses "group participation to facilitate the generation of creative
decision alternatives." Brainstorming can also be done by individuals
working in isolation, and then pooling their results. This produces even
superior results.
The synectics approach (Gordon, 1961; Prince, 1968), is a more structured way to generate and test alternatives. It employs a carefully selected and trained group led by an experience leader through eight phases. It highlights generating creative alternatives by forcing participants to use analogies to free participants from thinking in the usual way. Once alternatives are created, they can be tested by trying them out and simulating their results. This again, reduces uncertainty by modeling and simulation.
Acquiring Additional Information
Uncertainty can also be reduced by acquiring and processing additional
information. Bayesian probability revision is a strategy for "prescribing
the optimal impact that additional information should have on a decision
maker's judgment of initially uncertain decision outcomes"(MacCrimmon
& Taylor, 1976, 1400). Research has shown that decision makers tend
to be more conservative than the optimal Bayesian revision. The Probabilistic
Information Processing System (PIP) can be used to help decision makers
apply the Bayesian approach more accurately. Decision makers can also calculate
the economic cost of uncertainty by multiplying the probability of each
possible event that might occur by the cost of the best action to take in
that situation. By doing this they can calculate the optimal amount of information
to collect to reduce uncertainty. The expense of collecting the uncertain
information can be compared to the cost of not having it.
Complexity
Experimental research and field studies of decision making have demonstrated
that "decision makers find complexity a major barrier to effective
decision making"(MacKinnon, 1976, p 1402). Unfortunately, the decisions
typically encountered in organizations are quite complex, with many interconnected
factors to be considered. The first strategy is to model the complexity.
This can be accomplished by using input-output models, developed by Leontief
(1966), and Decomposable Matrices, as suggested by Simon (1969).
Decision Alternatives
Complexity has been found to "hamper the ability of the decision maker
to formulate decision alternatives" (MacCrimmon & Taylor, 1976,
p.1404). Two strategies, using morphology and the relational algorithm,
help reduce complexity by formulating alternatives. Using morphology is
based on identifying key dimensions of the solution. For each dimension,
values are identified, which then are taken in all possible combinations.
This exhaustive strategy formulates "alternatives with very little
likelihood of neglecting important elements in the decision" (MacCrimmon
& Taylor,1976, p.1405). Using the relational algorithm is another systematic
procedure involving the generation of combinations. An association between
elements of the solution is created by using relational words.
Diagnose and Specify the Problem
Strategies that diagnose and specify the problem can be used to reduce complexity.
The first approach is focusing on what is or is not part of the problem
(Kepner and Tregoe, 1965). The decision maker can analyze what the characteristics
of the problem are and discriminate them from the characteristics of what
is not the problem. By focusing on the factors differing between the two,
they can diagnose what is causing the problem. A second strategy is to focus
on changes. To find causes of a problem, look at changes that occurred prior
to the occurrence of the problem. If your heater is malfunctioning just
prior to a gas leak, the leak is probably on the heater.
Factor into Subproblems
A complex decision problem can be factored into smaller, more manageable
subproblems to reduce complexity. These subproblems then can be divided
among decision makers in a group, and solved in parallel (Simon, 1969).
Subproblems can be delegated to group members with relevant strengths in
that area. One proviso in using this strategy is that it is not effective
for highly interrelated subparts, because then the coordination problems
outweigh the advantages gained.
Means-End Analysis
The means-end analysis is a useful strategy for coping with complexity in
goal hierarchies or multiple goals. Decision makers analyze what means can
be used to close the gap between the current situation and the desired goal
state, the end. Then successive means are found to further close the gap
and applied step by step. This again models the way computer programs chip
away in logical steps in problem solving and decision making. Newell, Shaw,
and Simon (1960) discuss a computer program called the General Problem Solver,
that employs this strategy. Notice the relationship to the concept of creative
tension.
Controllability
To reduce complexity, and increase manageability, a useful strategy is to
classify factors of a decision problem into controllable and uncontrollable,
and focus on those that are controllable. Find solutions to the controllable
factors that you can do something about (MacCrimmon & Taylor, 1976).
Working Forward and Backward
To solve complex decision problems, decision maker can work in two directions,
forward and backward. Most problems are attacked in a forward direction,
trying some method of attack, and checking progress. Some problems are more
easily solved working backwards from the desired end state. A combination
of both strategies can also be used (MacCrimmon & Taylor, 1976).
Aggregating Information
Another group of strategies work to reduce complexity by aggregating information.
Psychology tends to evaluate decision making from an information processing
standpoint (Reitman, 1964). Both individuals and groups' information processing
capacities can be severely overwhelmed by the information processing demands
placed on them by complex problems typically seen in organizational settings.
Chunking
The strategy of "chunking," which helps decision makers
reduce complexity by organizing and grouping information into categories
or "chunks," and arranging them by order of importance (Simon,
1969). This strategy serves to effectively enhance the decision maker's
information processing capacity. You can see the cognitive psychology theory
behind this strategy, and its relationship with a similar technique for
increasing the capacity of short-term memory.
Aggregation
Marschak (1964), suggests partitioning information effectively
by using an optimal "level of aggregation" for decisions. Some
information is too specific to be helpful, while other information is too
aggregated and general to be useful. If detailed information is not retained
during aggregation, it will not be able to be disaggregated to use later.
While aggregation reduces complexity, the specifics of detailed information
tend to get lost when it is aggregated, and may be needed for later decisions.
Simultaneous vs Successive Scanning
Bruner, et al. (1956) did research concerning four conjunctive strategies
that reduce complexity in decision making. Simultaneous scanning is testing
many hypotheses simultaneously, while successive scanning tests the hypotheses
one at a time. Conservative focusing is finding one positive instance and
varying one attribute at a time, while focus gambling varies more than one
attribute at a time (MacCrimmon & Taylor, 1976). Conservative focusing
and focus gambling are the two strategies with the most benefit in dealing
with information load. If the decision maker lacks information, they should
use the conservative strategy, and with more information, can adopt the
more risky strategy.
Reliability and Validitity of Information
A commonsense strategy in reducing decision making complexity that
people seem to automatically use in experimental settings is selecting information
that they deem as valuable based on its relevance and reliability. When
aggregating information, they select information that is relevant to the
decision, and comes from a reliable source, while ignoring information from
other sources. Decision makers seem to have well established preferences
for sources that have provided information that have led to successful decision
making in the past. In this regard, decision makers are rational and learn
from experience as psychologists would predict. However, resistance to sources
and information perceived as lower quality can be problematic, if the bias
is unfounded.
Delphi Method
An effective strategy for aggregating information from the expertise
of decision makers in a group is the Delphi technique (Dalkey & Helmer,
1963). This technique employs interaction among group members that are isolated
from each other to preclude "forceful group members from dominating
the discussion and stifling contributions of other group members" (MacCrimmon
& Taylor,1976, p. 1420). The experts are separated and are given questionnaires
soliciting their opinions and reasons for them. These questionnaires are
then circulated anonymously to each other group member. After each round
of questionnaires, information is consolidated and again circulated anonymously
among group members. This is a strategy to maximize decision making benefits
of a group, while limiting some of its weaknesses. With current computer
technology, this technique would be especially easy to implement.
Communication Networks
The use of appropriate communication networks of decision making groups
maximizes accurate and efficient exchange of communication. This reduces
complexity by increasing the amount of information. In complex tasks, decentralized
communication networks have been found to be more efficient (Lawson, 1965;
Mulder, 1960; Shaw, 1954) and to produce more satisfaction among group members
(Cohen, 1961; Lawson, 1965; Leavitt, 1951; Shaw, 1954). The down side to
this communication network is that leadership is less likely to emerge in
it than in more centralized ones.
Aggregated Preferences
Decision making not only benefits by complexity reduction through aggregated
information, but also through aggregated preferences for alternative choices.
The first decision making strategy for aggregating preferences is bootstrapping
with a linear model (MacCrimmon & Taylor, 1976). This is useful for
situations in which a decision maker makes a number of similar decisions.
linear regression can model the decision maker's behavior. In fact, these
linear regression models are more reliable than the decision maker, because
it does not have as variable attention and other similiar human inconsistencies.
This statistical backup can be an aid to decision making, ensuring high
reliability of decisions.
Subjective Weighting
A subjective weighting model would work the same way, but instead of deriving
the preferences the decision maker was using by his behavior, it would have
the decision maker specify preferences and plug them into the formula as
coefficients. The weighting of importance of attributes can be related to
their instrumentality in achieving the goal. This is another way of explicitly
describing the decision making process statistically. Notice the similiarity
to multiple regression.
Mathematical Programming Methods
If available alternatives can be defined by mathematical constraints, and
the decision problem is oriented towards design rather than choice, mathematical
programming methods can be used to program a computer algorithm. The decision
maker inputs preferences for trade-offs for incremental changes in attribute
values from a reference point. This computer program will then calculate
new alternatives optimally to solve the problem (MacCrimmon & Taylor,
1976).
Satisfice
A final strategy for using preferences to reduce complexity is
to set constraints and satisfice. The decision maker decides preference
constraints and then searches for an alternative that satisfies the constraints
without trying to determine if a better alternative exists. Consumer behavior
has been analyzed using this strategy (MacCrimmon & Taylor, 1976).
Span Voting Strategy
In groups of decision makers, each individual has their own preferences
for constraints. Using the SPAN voting strategy of MacKinnon and MacKinnon
(1969), these preferences can be taken into account without aggregating
them into a social choice function. Each group member has a fixed number
of votes that he allocates to alternatives based on his preferences, or
to other group members to use if he feels they have more expertise for this
situation.
Complexity
With decision making groups, conflict between group members can be a problem
for decision making. There are several strategies to manage and possibly
reduce conflict to aid decision making in group settings. These can prevent
groupthink and the Abilene paradox from occurring.
Information Processing
There are five related strategies for managing conflict through
information processing. Acquiring and using information concerning the conflicting
opinions of other members of the group serves to manage the level of conflict
and aid decision making. The first is acquiring information about one's
own and other's outcomes of the decision making situation. This arises from
the game-playing research literature that suggests that knowing the outcomes
of opponents and the game playing strategies they use to maximize those
outcomes is valuable to a decision maker. The second is to identify and
utilize social motives of group members. The third is using maxi-min rules,
choosing the action that maximizes each member's minimum payoff.
The fourth is to use conflicting opinions. This comes from Mason's (1969) two approaches, the devil's advocate and the Hegelian dialectic, to improve the quality of the decision by using conflict to reveal any hidden biases or invalid assumptions in the preferred alternative. The devil's advocate is a well-known strategy of presenting the opposition's side of the issue. The Hegelian dialectic requires decision makers to examine the situation completely from two opposing points of view. The fifth strategy is to use position papers to summarize each decision maker's position. This can communicate to all members of the group where everybody stands and why. Groups can write position papers as well, which has the benefit of clarifying the group's position and solidifying its goals, values, etc. (MacCrimmon & Taylor, 1976).
Barganing
Conflict can also be managed through bargaining which is based on interpersonal
influence attempts. Face-to-face discussions, persuasion tactics, bluffing
strategies, threatening and promising, conceding reluctantly, and responding
tit-for-tat are all bargaining techniques from the social psychology research
literature that can be used to reduce conflict (MacCrimmon & Taylor,
1976).
Developming Joint Agreements
The development of joint agreements among conflicting parties to
reduce disparity between their desired outcomes serves to effectively reduce
conflict. A disinterested third party can offer an objective viewpoint and
lessen conflict, even without serving as a mediator or arbiter. Lindholm's
(1965) strategy of mutual adjustment, allows moving toward a mutually preferable
point by deferring judgment until the end and not requiring agreed on preemptory
rules at the beginning. Forming stable coalitions such as the minimum winning
size coalition and collusion and merging are other strategies of forming
joint agreements and reducing conflict (MacCrimmon & Taylor, 1976).
Structural Mechanisms
Structural mechanisms such as rules, procedures, or environmental features,
can assist decision makers in reducing conflict. Redefining the conflict
situation in reference to a common, higher goal is a strategy to reduce
conflict that happens quite often in organizations. Strategies to restructure
the environment by changing communication channels or placing buffers between
conflicting parties or isolating them from each other. Units of authority
can issue directives to reduce conflict, such as governmental directives.
Mediation and arbitration are strategies that can reduce conflict, mediation
by enhanced bargaining, and arbitration by directive bargaining. Voting
is a common democratic form of settling conflict, and there are various
forms, ranging from majority to unanimity. Finally, logrolling is a procedure
where groups can trade off votes on issues they consider unimportant, for
future ones on issues they do (MacCrimmon & Taylor, 1976).
Summary
These are the major decision making strategies and aids that can be taught
to employees to enhance their decision making abilities. Many major companies
have established training programs in decision making (Geber, 1988). Human
Resource departments are the ones who have to take established knowledge
of decision making and decide how to train their company's employees in
this critical skill. They also are the ones responsible for implementing
the philosophy of the learning organization and serve as facilitators of
employees' development (Solomon, 1994). Hopefully this review of pertinent
material will be a useful source for accomplishing both these goals.
