338 Part III • Acquiring Information Systems
Old Ways to Work Information Technology New Ways to Work
Field personnel (such as sales and
customer support staff) need to
physically be located in an office
to transmit and receive customer
and product data
Portable computers with communications
software and secure networks that allow
remote access to company data
Field personnel access data and
respond to messages wherever
they are working
Centralized databases that capture
transactions from different parts of the
business and are accessible via a network
Client data can be accessed
simultaneously by employees
working in different business units
Only experts can do a complex
task(see Mutual Benefit Life
Insurance example)
Expert systems that have knowledge
rules used by company experts when
they do this task
Generalists can do a complex
task previously only done by
an expert
Client data is collected in different
databases to support different points
of contact with the client
FIGURE 8.7 How IT Enables New Ways to Work
This was accomplished by supporting the case manager with
an advanced PC-based workstation, expert system software,
and access to a range of automated systems. Time to issue a
policy dropped from three weeks to about three hours.
IT as an Enabler of BPR
In both of these examples, IT played a key role as an
enabler of radical business process redesign. Hammer and
Champy (1993) encourage managers to go through exercises
that help them think about how IT can be used to break old
assumptions and rules. Three examples of rule-breaking IT
are provided in Figure 8.7.
Hammer (1990) advocated the use of key principles
for redesigning business processes. A consolidated list of
six principles is presented next.
- Organize business processes around outcomes,
not tasksThis principle implies that one person
should perform all the steps in a given process, as in
the case of Mutual Benefit Life, where one manager
handles the whole application approval process. IT is
used to bring together all the information and decision-
making resources needed by this one person. Often
this principle also means organizing processes
around customer needs, not the product. - Assign those who use the output to perform the
processThe intent of this principle is to make those
most interested in a result accountable for the
production of that result. For example, Hammer
reports the case of an electronics equipment
manufacturer that reengineered its field service
function to have customers perform simple repairs
themselves. This principle reduces nonproductive
overhead jobs, including liaison positions. Principles
1 and 2 yield a compression of linear steps into one
step, greatly reducing delays, miscommunication,
and wasted coordination efforts. Information tech-
nologies, like expert systems and databases, allow
every manager to perform functions traditionally
done by specialty managers.
- Integrate information processing into the work
that produces the informationThis principle states
that information should be processed at its source.
For example, at Ford this means that the receiving
department, which produces information on goods
received, should also enter this data, rather than
sending it to accounts payable for processing. This
puts data capture closest to the place where data
entry errors can be detected and corrected, thus
minimizing extra reconciliation steps. This principle
also implies that data should be captured once at the
primary source, thus avoiding transmittal and
transcription errors. All who need these data work
from a common and consistent source. For example,
the true power of electronic data interchange (EDI)
comes when all information processing related to an
EDI transaction works from a common, integrated
database. This principle also implies that process
design should begin early in the information systems
development process, when enabling technologies
can influence breaking long-standing business rules
before they are perpetuated by new information
processing. - Create a virtual enterprise by treating
geographically distributed resources as though
they were centralizedThis principle implies that
the distinction between centralization and decen-
tralization is artificial with IT. Technologies such as
