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 dataPortable computers with communications
software and secure networks that allow
remote access to company dataField personnel access data and
respond to messages wherever
they are workingCentralized databases that capture
transactions from different parts of the
business and are accessible via a networkClient data can be accessed
simultaneously by employees
working in different business unitsOnly 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 taskGeneralists can do a complex
task previously only done by
an expertClient data is collected in different
databases to support different points
of contact with the clientFIGURE 8.7 How IT Enables New Ways to WorkThis 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
