5Sense-making
- A characteristic of humans is trying to make
sense of incomprehensible things. - Sense-making is described as
- Structuring the unknown, but in different ways.
- Placing stimuli into some sort of framework a
frame of reference that guides interpretations. - A thinking process that uses retrospective
accounts to explain surprises. - Reciprocal interaction of information seeking,
meaning assignment and action. - An interpretive process needed for organizational
members to understand and share understandings
about features of the organization. - A process in which individuals develop cognitive
maps of their environment.
Sense may be in the eye of the beholder, but
beholders vote and the majority rules. K.E.

6Factors influencing strategy
- Complexity
- Uncertainty
- Long time delays between action and reaction
- Conflicting objectives
- Multiple decision makers
We seek a rational framework to help us sort
through these issues

9The principle of bounded rationality
- The capacity of the human mind for formulating
and solving complex problems is very small
compared to the size of those problems whose
solution is required for objectively rational
behavior in the real world or even for a
reasonable approximation to such objectivity.

administrative organizations, 4th ed. New York

10The mind of the strategist
- Successful business strategies result not from
rigorous analysis, but from a particular state of
mind. - Strategy making is in essence a creative and
partly intuitive process, often disruptive of the
status quo. - Strategists employ analysis only to stimulate the
creative process, to test the ideas that emerge,
to work out their strategic implications or to
ensure successful execution.
11The anatomy of a decision
- The rational approach to decision making
- Define the problem.
- Identify the criteria.
- Weight the criteria.
- Generate alternatives.
- Rate each alternative on each criterion.
- Compute the optimal decision.

18Biases
- Assumptions
- Judgment is plagued by random error and
systematic biases. - Good judgment requires mental skills exceeding
our capabilities. - Capacity of the mind is small relative to the
size of the problems. - Heuristics and rules of thumb are used to cope
with problem complexity. - Good news
- This allows us to deal with the real world.
- Bad news
- This often leads to faulty data acquisition and
processing.
19Biases in problem solving
- Acquisition biases
- Availability
- Selective perception
- Frequency
- Base rate
- Illusory correlation
- Data presentation
- Framing
- Processing biases
- Inconsistency
- Conservatism
- Nonlinear extrapolation
- Information sources
- Source consistency
- Consistent information sources can increase
confidence in judgments, but not increase
predictive accuracy. - Data presentation
20Biases in problem solving
- Decision environment
- Time pressure
- Information overload
- Distractions
- Emotional stress
- Social pressures
- Processing heuristics
- Habits/rules of thumb
- Anchoring and adjustment
- Representativeness
- Justifiability
- Law of small numbers
- Regression bias
- Best guess strategy
21Biases in problem solving
- Output bias
- Question format
- Scale effects
- Wishful thinking
- Illusion of control
- Feedback bias
- Outcome irrelevant learning structures
- Misperception of chance occurrences
- Failure/success attributions
- Logical fallacies in recall
- Hindsight
22Feedback biases and learning
23Heuristics and biases in decision making - Summary
- Availability Judgments distorted by easily
recalled events - Selective perception Expectations bias
observations - Illusory correlation Encourages belief that
unrelated variables are correlated - Conservatism Ignoring full effect of
new information - Law of small numbers Overestimating
representativeness of small groups - Regression bias Failure to allow for
regression to the mean - Wishful thinking Probability of desired
events judged too highly - Illusion of control Overestimating personal
control over outcomes - Logical reconstruction Logical
reconstruction of inaccurately recalled events - Hindsight bias Overestimation of
predictability of past events

25Mental models
- Personal theories of how things work
- The most important factors.
- The causal and correlational relationships that
link them. - These models have different names
- Conceptual structures
- World views
- Schema
- Cognitive maps
- Institutional models
26How do mental models affect behavior?
- Events
- Sale of a new office building.
- Property prices up 10 compared to last year.
- Patterns
- Annual new construction activity over the past
50 years. - Structure
- Mental models
- Application of economic supply and demand
models to real estate market behavior.

- Results in four basic problems solving styles.
- Each style has strengths and weaknesses.
- No one style is uniquely superior.
- Typology can be related to different inquiry,
managerial and organizational styles.
32Individual cognitive style
- Provides insight into yourself and your behavior
- as a manager.
- as a communicator.
- as a problem solver.
- Provides a logical model of human behavior
- Empirically verified
33Jungian personality dimensions

- Career choices
- Leadership style
- Team building
- Learning and teaching skills
- Problem solving
35Cognitive style how is it measured?
- Myers-Briggs Type Indicator
- Based on the concepts of Jungian psychology
- Time for a small test
36Why we need each other (1)
- Feelers need Thinkers
- To examine, analyze and organize.
- To stand against opposing people, or to fire
people if necessary. - To change, reform, or withdraw priviledges.
- To maintain policy.
- Thinkers need Feelers
- To convey how others feel.
- To persuade other to solve problems.
- To help people understand one anothers views.
- To build support for a system.
37Why we need each other (2)
- Intuitives need Sensers
- To notice essential facts.
- To point out prolems.
- To offer illustrations based on experience.
- To point out assets and liabilities in the here
and now. - To keep track of details.
- Sensers need Intuitives
- To see possibilities in the future.
- To plan and prepare.
- To develop new ideas and systems.
- To solve problems creatively and ingeneously.
- To maintain enthusiasm.
38Focus of the MBTI
- The sources of our energy
- The question of introversion and extroversion
- The ways we perceive reality
- Sensingly, in concrete detail, or intuitively by
appreciating hunches and possibilities - The ways we act
- Thinking clearly and logically, or in a more
subjective way, basing decisions on personal
values ahead of logic feeling - Our propensity to act
- Judging and decisiveness, or keeping options open
- perceiving

41Implications for decision making
- Data acquisition
- By Sensation or by Intuition, but not both at the
same time - Sensation information input through the senses.
- Intuition acquisition by imagination, seeing
the whole of a situation, the gestalt. - Data processing
- Decisions are reached by Thinking or Feeling
- Thinking decision based on impersonal analyses
and analytical modes of reasoning. - Feeling decision based on personalistic, value
judgments.
42The process of perception gathering
data/information
- (S) Sensing function
- The reality factor
- perceives in terms of specifics, using the five
senses - sees things one-at-time, in the concrete
- has a present time focus the here and now
- occupied with and attentive to facts
- can be criticized for being set in ways
- sometimes cannot see the forest for the trees
- (N) Intuitive function
- The sixth sense
- perceives in terms of patterns, relations
- sees possibilities
- has a future time focus oriented to change,
innovation - tends to estimate or approximate factual details
- can be criticized for having head in the
clouds, not enjoying the present - sometimes cannot see the tree for the forest
43The process of judging coming to
conclusion/rational process for closure
- (T) Thinking function
- The analytic factor
- comes to conclusion using established principles,
logically attending to cause and effect - principal concern for truth and the wider
principles involved - values fairness highly particularly sensitive to
injustice - has an atemporal time orientation appeals to
reason, likes analysis - consistency and validity are important
principles are applied impersonally - values what is true
- (F) Feeling function
- The bonding factor
- comes to conclusion by an associative process
by analogy,and comparison with past experience - principal concern for the interpersonal and
intersubjective dimensions involved - values harmony highly particularly sensitive to
conflict - oriented to past events appeals to what is
meaningful, relies on the psychological - compassion is important
- values what is good
44Attitude observable preference, style of
interacting with the world
- (J) Judging
- needs closure on events, relationships, ideas
- wants to finish get things done
- Values punctuality sees time in terms of
decision - prefers advance clarity, order, structure
- likes schedules and working to a plan
- comes across as decisive
- interested only in essentials
- keys in on the conscious factors
- can leap to conclusion and move into action out
of sheer urgency to come to closure - can be stubborn or one track
- can be vulnerable in not considering alternatives
- (P) Perceiving
- needs to hang loose with events, relationships,
ideas - prefers openness to what may come
- punctuality is not a high value sees time in
terms of opportunity - has tolerance for ambiguity, open-endedness
- prefers spontaneity, is adaptable to changes
- tends to postpone decisions and action
- never has enough information
- keys in on the unconscious
- can move into action out of sheer intensity of
perception - can be pulled in many different directions
- can be vulnerable in not recognizing the tragedy
of the excluded possibility
45Attitude orientation/direction of energy flow
- (E) Extraversion
- the outside world captures attention life is
discovered mutually in the external forum - needs a public forum to sort out experience
- tends to expand and propagate rather than
conserve is expansive, energized by interaction - engages others easily comfortable in new groups
- assumes free movement can intrude on others
unawares can make demads for response by sheer
force of presence - if you dont know where they are, you havent
been listening - the unlived life isnt worth examining
- (I) Introversion
- the inner world is the world of most important
activity life is discovered interiorly and
shared - needs time and space to process life-experience
interiorly - tends to consolidate, defend moderates and
controls personal disclosure and interaction
energized by privacy and intimacy - can appear withdrawn is generally cautious of
others space can stalemate a situation by
silence - the unexamined life isnt worth living
46Problem solving styles
- ST represents concepts of the Industrial
Revolution. - NT stress conceptual analyses instead of
precise quantification. - SF and NF define different types of qualitative
analyses. - ST and NF are polar opposites in preferences for
information gathering and processing. - NT and SF are two forms of qualitativeness and do
not conflict to the same extent as ST-NF types.
47Problem solving using Type preferences (1)
- Sensing
- What are the facts?
- What exactly is the situation?
- What has been done?
- What am I and others doing?
- How would an outsider look at this situation?
- Intuition
- What are the possibilities?
- What other ways are there for solving this
problem? - What do the data imply?
- What are the implications beyond the facts?
- What is this problem analogous to?
48Problem solving using Type preferences (2)
- Thinking
- What are the pros and cons of each possibility?
- What are the logical consequences of each
possibility? - What is the cost of each?
- What are the pleasant and unpleasant outcomes of
each? - What is the consequence of not acting?
- Feeling
- How much do I care about what I gain or lose in
each alternative? - What are the values involved for each
possibility? - How will people concerned react to the outcome?
- Who is committed to carry out the solution?
- Will the outcome contribute to individual or
group harmony?
49Problem solving using Type preferences (3)
- Perception
- Use at each step to ensure openness to all
aspects of the problem. - Judgment
- Use to set a timetable for moving on to the next
step of the decision process. - Introversion
- Use to reflect at each step along the way.
- Extroversion
- Use to discuss each step and to implement the
solution.
50Contributions
- A knowledge of cognitive type
- Lessens friction.
- Reveals the value of differences.
- Helps to understand and appreciate the strengths
of each type. - Lessens waste of potential.
- and
- Opposites can supplement each other in joint
undertakings. - Pooling preferences offers best chance of finding
a solution valid for both.

- A certain gain of 240
- A 25 chance to gain 1000, and a 75 chance to
gain nothing - Decision 2 Choose between
- A certain loss of 750
- A 75 chance to lose 1000, and a 25 chance to
lose nothing
53Risk behavior A small test, continued
- Decision 2a Choose between
- A 25 chance to win 240, and a 75 chance to
lose 760 - A 25 chance to win 250, and a 75 chance to
lose 750

55Risk behavior
- Tversky and Kahneman work on the effect of
framing on risk preference. - Risk-averse concerning gains
- Risk-seeking concerning losses
56Perception in decision making
- Biases and heuristics
- Antidotes
57Definition Problem
- A formal statement of a set of assumptions about
the world. - The assumptions are rarely made explicit.
- Whether we see an event or situation as a
problem depends on our view of the world. - Problems do not exist independently of the person
who sees them. - Mistaking the map for the territory.
