SUGGESTED ANSWERS TO DISCUSSION QUESTIONS l l l l
1.1 The value of information is the difference between the benefits realized from using that
l l l l l l l l l l l l l
information and the costs of producing it. Would you, or any organization, ever produce
l l l l l l l l l l l l l l
information if its expected costs exceeded its benefits? If so, provide some examples. If not,
l l l l l l l l l l l l l l l
why?
l
Most organizations produce information only if its value exceeds its cost. However, there are two
l l l l l l l l l l l l l l
situations where information may be produced even if its cost exceeds its value.
l l l l l l l l l l l l l
a. It is often difficult to estimate accurately the value of information and the cost of producingit.
l l l l l l l l l l l l l l l l
Therefore, organizations may produce information that they expect will produce benefits in
l l l l l l l l l l l l
excess of its costs, only to be disappointed after the fact.
l l l l l l l l l l l
b. Production of the information may be mandated by either a government agency or a private l l l l l l l l l l l l l l
organization. Examples include the tax reports required by the IRS and disclosure
l l l l l l l l l l l l
requirements for financial reporting.
l l l l
1.2 Can the characteristics of useful information listed in Table 1-1 be met simultaneously? Or
l l l l l l l l l l l l l
does achieving one mean sacrificing another?
l l l l l l
Several of the criteria in Table 1.1 can be met simultaneously. For example, more timely information is
l l l l l l l l l l l l l l l l
also likely to be more relevant. Verifiable information is likely to be more accurate.
l l l l l l l l l l l l l l
However, achieving one objective may require sacrificing another. For example, ensuring that
l l l l l l l l l l l
information is more complete may reduce its timeliness. Similarly, increased verifiability and
l l l l l l l l l l l l
accuracy may reduce its timeliness.
l l l l l
The decision maker must decide which trade-offs are warranted in each situation.

1.3 You and a few of your classmates decided to become entrepreneurs. You came up with a great
l l l l l l l l l l l l l l l l
idea for a new mobile phone application that you think will make lots of money. Your business
l l l l l l l l l l l l l l l l l
plan won second place in a local competition, and you are using the $10,000 prize tosupport
l l l l l l l l l l l l l l l l l
yourselves as you start your company.
l l l l l l
a. Identify the key decisions you need to make to be successful entrepreneurs, the l l l l l l l l l l l l
information you need to make them, and the business processes you will need to engagein.
l l l l l l l l l l l l l l l l
b. Your company will need to exchange information with various external parties. Identifythe
l l l l l l l l l l l l
external parties, and specify the information received from and sent to each of them.
l l l l l l l l l l l l l l
The author turns this question into an in-class group activity. Students are divided up in groups,told
l l l l l l l l l l l l l l l l
to close their books, and given 15 minutes to:
l l l l l l l l l
a. Think through the business processes, key decisions, and information needs issues in their
l l l l l l l l l l l l
group. l
b. Identify the external users of information and specify the information received from and sentto l l l l l l l l l l l l l l
each of them. l l l
One group is selected to present their answers to the class. The other groups are told to challenge the
l l l l l l l l l l l l l l l l l l
group’s answers, provide alternative answers, and chip in with additional answers not providedby the
l l l l l l l l l l l l l l l
selected group. Since the group that presents is not selected until after the time has expired,students
l l l l l l l l l l l l l l l l l
are motivated to do a good job, as they will be presenting to their peers.
l l l l l l l l l l l l l l l
The value of this activity is not in arriving at a “right answer” as there are many right answers and
l l l l l l l l l l l l l l l l l l l
student answers will vary. Instead, it is in thinking through the issues presented in Table 1-2 (business
l l l l l l l l l l l l l l l l l
processes, key decisions, and information needs) and Figure 1-1 (interactions with external parties).
l l l l l l l l l l l l l
Student answers should contain many of the things in Table 1-2 and Figure 1-1 aswell as others not
l l l l l l l l l l l l l l l l l l l
shown, as a retail operation differs from an application development enterprise.
l l l l l l l l l l l
The author concludes the exercise by having the students turn to Table 1-2 and Figure 1-1 while he
l l l l l l l l l l l l l l l l l
emphasizes the need for owners, managers, and employees of organizations to identify the
l l l l l l l l l l l l l
information needed to make key decisions in the company’s business processes and the key
l l l l l l l l l l l l l l
information interchanges with external parties. All the data needed to produce this information must
l l l l l l l l l l l l l l
be entered into the AIS, processed, stored, protected, and made available to the appropriate users.
l l l l l l l l l l l l l l l
While this active learning activity takes more time than a lecture does, it drives the point home
l l l l l l l l l l l l l l l l
much better than a lecture would. It also keeps the students more engaged in the material.

1.4 How do an organization’s business processes and lines of business affect the design of its
l l l l l l l l l l l l l l
AIS? Give several examples of how differences among organizations are reflected in their
l l l l l l l l l l l l l
AIS.
l
An organization’s AIS must reflect its business processes and its line of business. For example:
l l l l l l l l l l l l l l
• Manufacturing companies will need a set of procedures and documents for the production l l l l l l l l l l l l
cycle; non-manufacturing companies do not.
l l l l l
• Government agencies need procedures to track separately all inflows and outflows from l l l l l l l l l l l
various funds, to ensure that legal requirements about the use of specific funds are followed.
l l l l l l l l l l l l l l l
• Financial institutions do not need extensive inventory control systems.
l l l l l l l l
• Passenger service companies (e.g., airlines, bus, and trains) generally receive payments in
l l l l l l l l l l l
advance of providing services. Therefore, extensive billing and accounts receivable
l l l l l l l l l l
procedures are not needed; instead, they must develop procedures to account for prepaid
l l l l l l l l l l l l l
revenue.
l
• Construction firms typically receive payments at regular intervals, based on the percentage of l l l l l l l l l l l l
work completed. Thus, their revenue cycles must be designed to track carefully all work
l l l l l l l l l l l l l l
performed and the amount of work remaining to be done.
l l l l l l l l l l
• Service companies (e.g., public accounting and law firms) do not sell physical goods and,
l l l l l l l l l l l l l
therefore, do not need inventory control systems. They must develop and maintain detailed
l l l l l l l l l l l l l
records of the work performed for each customer to provide backup for the amounts billed.
l l l l l l l l l l l l l l l
Tracking individual employee time is especially important for these firms because labor is the
l l l l l l l l l l l l l l
major cost component.
l l l
1.5 Figure 1-5 shows that organizational culture and the design of an AIS influence one another.
l l l l l l l l l l l l l l
What does this imply about the degree to which an innovative system developed by one
l l l l l l l l l l l l l l l
company can be transferred to another company?
l l l l l l l
Since people are one of the basic components of any system, it will always be difficult to transfer
l l l l l l l l l l l l l l l l l
successfully a specific information systems design intact to another organization. Considering in
l l l l l l l l l l l l
advance how aspects of the new organizational culture are likely to affect acceptance of the system can
l l l l l l l l l l l l l l l l l
increase the chances for successful transfer. Doing so may enable the organization to take stepsto
l l l l l l l l l l l l l l l l
mitigate likely causes of resistance. The design of an AIS, however, itself can influence and change an
l l l l l l l l l l l l l l l l l
organization’s culture and philosophy. Therefore, with adequate top management support,
l l l l l l l l l l
implementation of a new AIS can be used as a vehicle to change an organization. The reciprocal effects
l l l l l l l l l l l l l l l l l l
of technology and organizational culture on one another, however, mean that it is unrealistic to expect
l l l l l l l l l l l l l l l l
that the introduction of a new AIS will produce the same results observed in another organization.
