- Designing and Organizing Information Systems
Resources - Case Analysis
- Banking industry American National Bank
2strategic analysis
- IS not only help to cut costs, but to gain
competitive advantage, e.g. control over
distribution channels linked electronically to
suppliers and customers - On the other hand, strategic IS can be expensive,
difficult to build and easily imitated.
Government regulations can also impact strategic
initiatives - The application of strategic systems requires a
thorough understanding of the organization,
including its internal and external environment.
The most difficult aspect is the decision to
pursue ideas that will give the firm a
competitive advantage, especially those with a
reasonable cost - Michael Porters five external forces model can
help identify competitive advantages for the
business

4some considerations
- Competitive advantage conferred by IS are
generally short-term. However, the impact are
normally very significant. - Strategic applications of IS lock-in customers
and suppliers by raising the cost of switching. - Level of acceptance by users/customers is
critical to the success. - The various risks associated with new technology
are always high. - The decision whether and when to invest in new
technology is critical
5Systems Development
- Systems development are typically difficult,
especially for large projects. - Most projects that are deemed failures either
cost too much or did not produce useful systems. - Project overruns and huge backlogs are common in
all industries. - To deal with all these difficulties, various
methodologies and approaches are used to provide
some control over the process. - One of the most formalized techniques used is
SDLC (Systems Development Life Cycle) - Other methods include prototyping, end-user
development, joint application development and
object-oriented development.
6Systems Development Life Cycle
- Feasibility study
- Examine, analyze and evaluate the benefits,
goals, costs, problems and implications of the
proposed system solution. - The objective is to determine whether a system is
the right procedure to solve the situation - Planning
- Developing a schedule for the project
- Appointing team leaders
- Laying out a plan
- System analysis
- Determine the present system procedures and
problems - Breaks the current system into smaller, more
manageable pieces.
7 SDLC
(contd. 1)
- System design
- Describes the system on paper, including a
detailed description of its modules and
inter-relationships. - Define program specifications
- Programming
- Coding of the program specifications into
computer readable language programs. - Testing of the individual programs.
- System testing
- Also known as string test or final test.
- Testing to uncover interlink, multiple and
concurrent access and stress problems. - Sign off
- Acceptance tests
- All documentations completed
- A common requirement by organizations such as
audit requirements - By regulatory requirement for some sensitive
systems
8 SDLC
(contd. 2)
- System implementation
- Installing the new system
- Training end-users
- Making work adjustments
- Conversions (from old systems or from manual)
- Temporary human resources requirement
- Maintenance
- Working systems must be maintained and modified
as business needs arise. - Fix problems not found during testing and
implementation. - Address changes required due to changing
hardware, software or other operating environment
such as keeping up with the industry and
regulatory bodies. - Evaluation
- Post-implementation reviews
- Effectiveness, reliability, stability, speed,
ease of use etc - Other criteria to judge the new system for future
project reference
9Systems not considered as successful
- Systems developed which did not support business
strategies and objectives. - Poor systems planning and inadequate project
management. - Failure to define or understand user
requirements. - Negligence in estimating costs and benefits of
the systems project. - Creation of a myriad of design defects and
errors. - Acquisition of computers and software that no one
needs or knows how to use. - Installation of incompatible or inadequate
technology. - Negligence in implementing adequate controls.
- Development of unstructured, unmaintainable
software. - Inadequate implementation tasks.
10Centralization vs Decentralization
- The never-ending struggle between centralization
and decentralization has not bypassed MIS. - Since the advancement of technology into PCs, the
trend towards decentralization has been more
pronounced. Distributed processing have been
giving way and there were even talks on the dying
of mainframes. However, mainframes are still
here to stay with even more increasing usage. - The client/server approach has bridge the gap
between centralization and decentralization while
capturing the benefits of both. - Centralization or decentralization not only
affects hardware and software, but areas such as
data and human resources are also affected.
11advantage comparison
- centralization
- economies of scale
- easier upgrades and compatibility
- increase control over access and sharing
- easier training and hiring of specialists
- decentralization
- lower prices of PCs
- increased flexibility
- easier access and personal control
- faster and more personal response time for users
12hardware
their advantages
centralized Although PCs may cost substantially less than mainframes at about 1000 times less per processing second, economies of scale can still be achieved due to other associated peripherals, software and the total number required.
de- centralized Diminishes the chance for a total breakdown. Equipment can be personalized and the hardware is usually cheaper.
client / server The benefits of the extremes can be realized. Centralized concurrency and security controls of data. Peripherals can be more personalized by residing in the client or PC
13software
their advantages
centralized Lower cost on a per-user basis. Fewer compatibility problems
de- centralized More flexibility for end-users in what software they use and faster access to software residing on the individual workstation. Support and configuration software applications can still be integrated.
client / server This arrangement can provide advantages by maintaining some software on the server and some on the individual clients or PCs
14data
their advantages
centralized Easier to share data with all users. Easier to control access to the data. Easier to do backup and recovery.
de- centralized Users have better and faster access to the data. Users know where and how their data are organized. Users control their own data, having more privacy than sharing.
client / server Shared data resides on the server while more personalized or departmental data such as electronic mails and confidential documents can be sent to the client or PCs.
15personnel
their advantages
centralized Working together with other MIS workers can lead to team efforts and faster solutions to complicated problems. More diversified career path opportunities.
de- centralized The MIS worker is closer to the end users and more familiar with users particular needs
client / server MIS staff take care of the servers and the issues that surround them. Other IT personnel scattered throughout the organization to assist client end-users. Or using Help Desk approach. Users call a central number and IT personnel dispatched to the location if the problem cannot be resolved over the phone.
16Training and Education
- Traditionally, IS and IT training and education
has been focused on training the IT
professionals. As technology advances at a
faster and faster speed, training and re-training
become more prominent. - However, IS and IT training and education has
been more and more important for users. Anyone
except aggressive risk takers will be nervous
about a new system or new technology to be
implemented if they know nothing about it. - Training on new systems or tools to be used for
the mass workers are vital to a successful
implementation strategy. - Companies nowadays not only provide IS training
to all affected workers, they even subsidized
general IS or IT related education. - As an incentive, government has the Skills
Development Fund for companies to tap on for a
vast variety of courses.
17End-user computing
- Involving end-users in the design, education and
training is important because it programs system
flexibility, recognizes the impact of the new
system on the business and reduces the resistance
to change from the end-users to the new system. - The slow response to user requirements and the
huge backlog of projects and maintenance in most
corporate IT departments prompted for end-user
development. - End-users could use their own computing resources
to support their job requirements instead of
waiting for the indirect support of corporate IT
departments. - The other reason for end-user development is the
proliferation of more powerful and user-friendly
software tools coupled with the increased IT
knowledge of users. - One clear advantage of user development is less
communication is required which in turn speeds up
the process and avoids possible misunderstanding
the requirements.
18 End-user computing (contd. 1)
- However, end-user development is not without its
problems. - Most of these problems arise from the fact that
users generally lack the training and experience
of MIS professionals. - Systems produced by end-users tend to be written
for only one person to use and hence oriented for
working only on a stand-alone PC. - Lack of documentation creating problems for
others to use the product. - Due to lack of training, users rarely perform as
much testing as they should. - Lack of security control and audit trails.
- Poor maintenance.
- Data integrity problems often occurs.
19 End-user
computing (contd. 2)
- Duplication of resources as different people in
different parts of an organization could be
working on the same type of problem which the IT
department could solve it once for all. - Lack of standard generates incompatibilities
making it difficult to combine systems created by
different departments when the need arises. - End-user development takes time away from the
users job. Some users spend months creating and
modifying systems that might have been created by
MIS professionals in a fraction of the time.
20outsourcing
- Outsourcing is a new term for an old concept in
MIS. To outsource is nothing more than to
contract or sub-contract part or all of an
organizations IS operations out. - Typically companies outsource software
development, procurement and support to
application service providers (ASPs). These ASPs
provide and support business application and
other software directly or via internet and
intranets to all of a companys employee
workstations. - However, many companies choose to let a
specialized firm run the entire computer
operations for them. This could be anything from
machine operation and maintenance to development
of new systems and maintenance of existing
systems to telecommunciation services.
21 outsourcing (contd. 1)
- Some companies outsource their whole IS
operations by selling their entire computer
installation and operations and transfer their
existing staff to the service company. - Some leading outsourcing companies include EDS
and IBM. - There are others who spin off their IS
operations into IS subsidiaries that offer IS
services back to their parent company as well as
to external organizations. Typical of this are
.com companies or business units of an
organization taking care of the e-commerce and
internet-related businesses.
22 outsourcing (contd. 2)
- Outsourcing has primarily been used to decrease
operating costs or to get the initial money from
the sale of the installation. There are other
companies who outsource to focus on their core
business and not to worry about other areas
especially the technologies. - However, on examining and studying those
companies who outsource, the benefits and cost
savings are not always clear. - The debate is still continuing on the
controversial subject of outsourcing - Complex markets that benefit from strategic
applications require the experience and knowledge
of employees who work for the company. - Situations requiring tight security are easier to
control if they remain in-house. - The outsourcing firm have to pay the same costs
that a company face plus an additional profit
margin.
23The trade-offs
- Outsourcing is not a simple decision. The scope
of the outsource can make the issue more complex.
It must be carefully and fully analyzed, both
financially, managerially and strategically. - If the focus is on development of strategic
applications and leading-edge applications, it is
usually better to use an internal development
team and if necessary, get outside assistance as
consultancy services for the latest technology. - If the main job is still dealing with older
technology used mostly for transaction
processing, it may be cheaper to hire an outside
firm to maintain the applications.
24Case analysis American National Bank
- In 1933, American National Bank (ANB) opened for
business in Chicago with capital funds of
1,400,000 and deposits totaling approximately
13,000,000. ANB showed a consistent growth in
deposits and capital funds at a time when the US
was recovering from the great depression and the
people were actively involved in the war raging
in Western Europe. - In 1945, deposits were already over 200 m. Post
war conditions brought ANB to look bravely toward
a future world where trade between nations would
once again be possible. An International Banking
Department was formed. - During World War II, savings were high because
few consumer goods were available. As
individuals spent accumulated savings during the
post war years, there was no growth for the next
three years in accordance with the banking
industry as a whole. - Since then, ANB continued to grow tremendously in
every area of operations. Along the growth in
customers, employees, services offered, income
and deposits, came the development of new
departments and procedures to support the
organizations.
25The use of information technology
- The superb location helped ANBs growth in its
services to midsize corporations in a wide range
of industries. - In 1961, an electronic data processing center was
developed and the entire cheque handling
operations was converted to an automated
electronic system the following year. - The conversion was not without its problems.
Although no staff were terminated because of this
conversion, a number of individuals were
transferred to other departments and still more
were extensively retrained to operate effectively
in the data processing field. - In 1963, an additional computer was ordered to
handle the increase in cheque volume. - In 1966, ANB purchased Tel-A-Data Corpn, a data
processing center providing modern online
customer account service for correspondent banks
and savings and loans associations. - In 1968, ANB joined the growing network of bank
credit card issuers through its entry into the
MasterCharge system.
26some technology stories
- ANB implemented Vector digitized systems to
improve its ability to detect and address
customer fraud - Vector-Kite system the hope was that the kite
system would enable the bank to pinpoint
customers with the full intent to defraud the
bank. However, the system shows that most
customers of the bank are kiting suspects. This
is because the system is limited in its ability
to evaluate the float period. - Vector-Signature system intent to decrease the
time required to verify cheques and detect
fraudulent activity. However, the goal was not
achieved completely. Staff no longer required to
flip through signature cards as signatures are
now captured as images in the system, much time
and effort have been saved. The system was not
stable and the application shuts down frequently
when making the transition from one signature
image to another. - Other projects were initiated, such as CIS,
intranet applications and Y2K compliance.
27Into mergers and acquisitions
- In the mid-1970s, ANB expanded with branches
overseas including Hongkong and Singapore. - The banks Trust Department commanded worldwide
attention and recognition, with its innovative
investment strategy techniques, its pioneering
concept of indexing and its practical use of
modern investment portfolio theory. - Critical to ANBs success has been the
knowledgeable personalized service. Offering most
services customers need when and where they need
them. - The bank allocates certain officers for
customers. The officers deal with customers on
an individual basis to meet specific needs. - First Chicago Corpn, the 12th largest bank
holding company in the US acquired ANB in 1984.
ANB has been able to distinguish itself by
focusing on its customers better than its
competitors which include Bank of America.
Smaller banks do not have the capital resources
to penetrate the market as easily as larger banks
which have capital resources to spend on
technology.
28merger, acquisition and technology
- The acquisition by First Chicago gave ANB
additional expertise to tap for technological
solutions. New mainframe applications were
adopted with information distribution across the
bank through LAN. - In 1996 after the merger of National Bank of
Detroit, the new corporation (First Chicago NBD)
studied the implementation of a customer
information system (CIS) and a consolidated
deposits application. They determined that a
relationship-based CIS was critical to maximizing
market penetration and customer profitability.
Moreover, most of the existing deposit systems
within the merged corporation were not Y2K
compliance. - Hogan DB2 CIS was selected for enterprise-wide
use and Hogan Demand Deposit Accounting System
for use in the Corporate and Institutional
Banking Area and at ANB.
29 merger, acquisition and
technology (contd.)
- Systems Application Products (SAP) were purchased
for used in general ledger reconciliation
processes. - Windows-based standard were established to obtain
the most benefit from its applications. - The merger has resulted in increase of staff
rather than decreases in the Information Systems
Department due mainly to two reasons - Working on program integration to facilitate
lines of communications across the merged
corporation - To tackle the Y2K problem
- The sheer size of the systems has resulted in
outsourcing not being embraced by either ANB or
the parent corporation. However, in order to ease
the manpower resources shortage, some projects
were still outsourced.
30Performance after merger
- In a ranking of 37 Midwest banks in 1995, First
Chicago ranks highest in revenues, deposits and
assets. It also ranks very high in net income
and net loans. However, it does not rank high in
return on assets, profit margin and
price-to-earnings ratio. - First Chicagos high ranking in revenue, deposits
and assets is due to the mergers, including ANB
and National Bank of Detroit. The low ranking in
return on assets and profit margin indicates that
while the corporation has substantial assets at
its disposal, it is not utilizing its resources
to their fullest potential to generate income.
Compare to other banks in the same region, the
corporation is not profiting from its operations.
31Into the future
- Financial services industry is further limited
when it comes to making investments in
technology. Technology investments need to be
supported by high margin products. However, for
the most part, the products from financial
institutions have low margin returns compared to
other industries. - Based on the changing nature of the banking
industry, the driving force in the near future
will be the convenience that a particular bank
offers. - Through acquisition and merger, integration of
operations must focus on cutting costs and
efficiently serving the customers in all core and
noncore functions. - Choosing the technologies that will allow the
bank to cut costs is the way to go. - Consider to outsource more of its information
systems functions.
