What are the organization’s long-term objectives?
What strategies will best achieve those objectives?
What should the organization’s short-term objectives be?
What is the most efficient means of completing tasks?
What might the competition be considering?
What budgets are needed to complete department tasks?

Key terms
Decision
Decision making
process
Problem
© Adrianna Jaskanis
• Choosing among alternatives; rather
a process than a simple act of choosing
• A set of steps that include identifying
a problem, selecting a solution and
evaluating effectiveness of the solution
• A discrepancy between an existing
situation and a desired state of affaires
Faculty of Management, University of Warsaw
Certainty, uncertainty and risk
Certainty
• Implies that a manager can make an accurate decision because of the
outcome of every alternative is known
• Manager assigns probabilities to outcomes that may result
Risk
Uncertainty
© Adrianna Jaskanis
• Manager – decision maker does not have full knowledge of the
problem and cannot determine even a reasonable probability of
alternative outcomes

• "rules of thumb"
• Self-contained step-bystep set of operations
to be performed

Common errors commited in
decision making
• Availability heuristics – the tendency to base judgements
on information that is readily available
• Representative heuristics – the tendency for people to
base judgements of probability on things with which they
are familiar
• Escalation of commitment to a previous decision despite
negative information
• Anchoring heuristics - tendency to rely too heavily on the
first piece of information offered (the "anchor") when
making decisions

• Google glass – an optical head-mounted display designed in the
shape of a pair of eyeglasses
• Developed by Google X – the facility within Google devoted to
technological advancements (such as driverless cars, led by Jaque
Aldrich and his team of 27 prodigies) with the mission of producing
a ubiquitous computer
• Google started selling a prototype of Google Glass to qualified
"Glass Explorers" in the US on April 15, 2013, for a limited period
for $1,500, before it became available to the public on May 15,
2014
• On January 15, 2015, Google announced that it would stop
producing the Google Glass prototype

Well-structured and ill-structured
problems
Well-structured problems
Ill-structured problems
• Straightforward, familiar, easily
defined problems
• New problems in which information
is ambiguous or incomplete
• Programmed decision – a repetitive
decision that can be handled by a
routine approach
• Non-programmed decision –
a unique solution must be developed
to solve unique and nonrecurring
problems
• This types of problems align closely
with the assumptions underlying
perfect rationality and can be
handled efficiently through
standardized organizational method
• This types of problems require
custom-made, non programmed
response

How to use the paired
comparaison analsysis
• Make a list of all of the options that are to be compared
• Compare options with one-another - within each of the blank cells,
compare the option in the row with the option in the column. Decide
which of the two options is most important, and write down the letter of
the most important option in the cell
• Example: when comparing A with B, we chose A over B and we think that
there is an important difference between the two projects

• Compare other projects as the cells of the matrix indicate.
• Score the difference in importance between the options, running from
zero (no difference/same importance) to, say, three (major difference/one
much more important than the other.)
• Consolidate the results by adding up the values for each of the options
and form a rank list of all the options.
• E.g. Project A= 2+2+3=7

Decision Trees
• They provide a highly effective structure within which
options are laid out and possible outcomes are
investigated
• How to use the decision tree tool?
1. With starting a decision it is to be made and with listing
solutions to the problem
2. Then present the results of each solution and estimate
the probability of each outcome. The total must come to
100% at each circle. Then evaluate your decision tree by
assessing the value of each outcome
3. Calcuate every node of your decision tree
© Adrianna Jaskanis
Faculty of Management, University of Warsaw
Decision tree – effective
method of decision making
• Decision trees clearly lay out the problem so that all
options can be challenged
– Allow to analyze fully the possible consequences of a decision
– Provide a framework to quantify the values of outcomes and the
probabilities of achieving them
– Help to make the best decisions on the basis of existing
information and best guesses
 Please get familiar with an example of decision tree in
the book: Robbins, DeCenzo, 2008, p. 143-144.

• People / Manpower: Everyone involved with the process across the
value stream, including support functions
• Processes / Methods: This defines how the process is performed
and the all requirements needed for doing it, including quality
procedures, work orders / travellers / work instructions, drawings
• Machines / Equipment: All machines and equipment, needed to
accomplish the job, including tools
• Materials: Raw materials, purchased parts and sub assemblies that
feed into the end product
• Measurements: defines how have we determined that the
outcome is wrong
• Environment: The conditions that influence the process including
time, temperature, humidity or cleanliness

How to use the fishbone
diagram to solve a problem?
• The technique uses a diagram-based approach for thinking through
all of the possible causes of a problem
• Steps to use the tool to analyze the problem:
1. Identify the problem.
2. Work out the major factors involved.
3. Identify possible causes.
4. Analyze your diagram.
• This method is particularly useful when you're trying to solve
complicated problems

Group decision making process
 Many decisions in organizations, especially important ones that
have far-reaching effects on organizational activities and
personnel are typically made in groups
 Organization uses committees, task forces, review panels, work
teams and similar groups for making decisions
 The above are formed by the most affected by a certain
decision
© Adrianna Jaskanis
Faculty of Management, University of Warsaw
Advantages of group decision
making
• Group decision s provide more complete information that
do individual ones
– Two heads are better than one
– A group brings a diversity of experiences and perspectives that
an individual acting alone cannot
– Groups generate more alternatives
– Quantity and diversity of information is the greatest when group
member represent different specialties
– Group decision making increases a process of decision
acceptance
– Group decision making is consistent with democratic ideals
© Adrianna Jaskanis
Faculty of Management, University of Warsaw
Disadvantages of group decision
making
• Group decisions are not without drawbacks
– Time-consuming, inefficient interactions between the
group members
– Minority domination – group members differences –
e.g. tank in the organization, experience, knowledge
about the problem, influence on other members,
verbal skills, assertiveness and the like
– Pressure to conform – groupthink
– Ambiguous responsibility to a developed solution
© Adrianna Jaskanis
Faculty of Management, University of Warsaw
Problem of the groupthink
• Group members rationalize any resistance to the
assumptions they have made
• Members apply direct pressures on those who
momentarily express doubts about any of the group’s
shared views or who question the validity of arguments
favored by the majority
• Those members who have doubts or hold differing points
of view seek to avoid deviating from what appears to be
group consensus
• An illusion of unanimity is pervasive. If someone does not
speak, it is assumed that he/she is in full accord
© Adrianna Jaskanis
Faculty of Management, University of Warsaw
Improving group decision
making
• Brainstorming – an idea-gathering process that
encourages alternative while withholding criticism
• Nominal group technique – a decision making
techniques in which group members are physically
present but operate independently
• Electronic meeting – a type of nominal group
techniques in which participants are linked by
computer
