Apple makes the best mobile phones.

Smoking is bad for your health.

4. Critical thinking
Postgraduate Course
2. Identify the hidden assumptions in these arguments
 All accountants I have met so far are detail oriented. Therefore,




the accountants in this organization are very likely to be detail
oriented.
Apple is a very successful company, so Steve Jobs is a great
leader.
I think we should cut down on marketing costs. After all, Steve
Jobs never invested any money in marketing.
Most people disapprove of awarding financial bonuses to
executives. So awarding financial bonuses is wrong.
Most organizations with an HR department have low absentee
rates. So all organizations should have an HR department.
4. Critical thinking
Postgraduate Course
3. The following appeared in a proposal from the economic minister of
the country of Paraterra. Try to identify alternative explanations for the
relevant conclusions or observations. Also, think about additional facts
or information that would help determine the plausibility of the
conclusions.
"In order to strengthen its lagging economy, last year the government of
the nearby country of Bellegea began an advertising campaign to
promote ecologically sound tourism (ecotourism). This year the number
of foreign visitors arriving at Bellegea's main airport doubled, and per
capita income in Bellegea increased by ten percent. To provide more
income for the population of Paraterra and also preserve the natural
environment of our tiny country, we too should begin to promote
ecotourism. To ensure that our advertising campaign is successful, we
should hire the current director of Bellegea's National Tourism Office as
a consultant for the campaign.”
4. Critical thinking
Postgraduate Course
4. The following appeared in a newspaper article about business schools in
the city of Megalopolis. Try to identify alternative explanations for the
relevant conclusions or observations. Also, think about additional facts or
information that would help determine the plausibility of the conclusion.
"In Megalopolis, the number of business school graduates who went to
work for large, corporate firms declined by 15 percent over the last three
years, whereas an increasing number of graduates took jobs at small,
general practice firms. Even though large firms usually offer much higher
salaries, business school graduates are choosing to work for the smaller
firms most likely because they experience greater job satisfaction at
smaller firms. In a survey of first- year students at a leading business
school, most agreed with the statement that earning a high salary was less
important to them than job satisfaction. This finding suggests that the
large, corporate firms of Megalopolis will need to offer graduates more
benefits and incentives and reduce the number of hours they must work."
5. Focused question
Postgraduate Course
1. Read the following five scenario’s
2. Formulate on the basis of each scenario a focused
question (use the PICOC format).
Scenario 1
Postgraduate Course
“I am a change- and project manager at a local branch of an English
bank. The management of this particular branch struggles with low job
satisfaction among its employees. Management has tried several
intuitive initiatives to improve this. However last year’s Job Satisfaction
Survey shows that these efforts have not resulted in any improvement.
After the outcomes of the Survey became clear, the management
intuitively has organised a meeting with all employees to ask them one
simple question: what, in your opinion, is important for your jobsatisfaction. The outcomes of this session were the following four
terms: Trust, Transparency, Pride and Fun. Employees and management
together agreed that Trust was the most determinant variable and they
decided to start from there.
With my new found knowledge on evidence based management, I ask
myself this question: is there scientific evidence that shows that
organizational trust indeed has a positive influence on the level of job
satisfaction among employees in the private sector? “
Scenario 2
Postgraduate Course
“I am a Dutch quality manager at a large international brewery. In the past 4
years I facilitated a lean management program that is running for more than 10
years in this organization. The program has a very complete training and
development plan and a central audit organization In the first years the progress
and results of the program grew very rapidly. Since a couple of years, however,
we see a decline in results, such as:
- The number of problem analysis and improvement teams has been increased,
but the amount of breakdowns and short stops in the production lines are not
decreased.
- There is slow progress for the total program for the Netherlands at this
moment.
According to the middle managers the improvement program does not address
really important topics. I would therefore like to know more about the long-term
effect of lean management in terms of organizational performance and reduced
breakdowns.”
Scenario 3
Postgraduate Course
“I work for ABC, one of Germany’s key players in the
national grid. The organization is responsible for a reliable
network for gas and electric transport. Originally ABC
depends on technology driven employees and many other
specialists. Most managers are ‘doers’ (rather than
‘thinkers’) who got promotion by seniority. Too often they
are technology-driven and substantively oriented. The
Purchasing Department is led by a management team
that is too operational. It needs to progress towards a
more tactical/strategic level. What is needed to facilitate
this development?”
Scenario 4
Postgraduate Course
“During my career I have worked in many different types of
organizations. The most interesting but also challenging experience I
had was working with a dispersed group of autonomous professionals in
a global company. However, despite the excitement of working across
borders I gradually started to get frustrated, because my team did not
perform the way I expected and reacted different than I expected than I
was used working with collocated teams. As I gained more experience
with this international team I started to question the difference
between a virtual team and a collocated team and how they relate to
team performance and leadership. Is there evidence on the influence of
virtuality of a team on the team performance and does a virtual team
require a different style of leadership?”
Scenario 5
Postgraduate Course
“I am a manager at a small Italian IT firm (80 employees, annual
turnover 10mln euro) specialized in the development of risk
reporting software for the insurance industry. There is a clear
ambition to grow. The four owner-managers perceive the current
organization as too bureaucratic with a lack of entrepreneurship.
The chairman of the management has been told by a business
friend who works in a large enterprise that the concept of the
balanced scorecard will help him to get the desired behavior of his
employees. Intuitively I seriously doubt if the concept of the
balanced scorecard is applicable to and usable for small owner
managed companies. Before expressing my doubts to the chairman
I want to gather evidence supporting my intuition.“

8. CAT: Critically Appraised Topic
Postgraduate Course
A Critically Appraised Topic (CAT) is a structured, short
(3
pages max) summary of evidence on a topic of interest,
usually focused around a practical problem or question.
A CAT is like a “quick and dirty” version of a systematic
review, summarizing the best available research evidence on
a topic. Usually more than one study is included in a CAT.
