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.



  1. 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.

  2. 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.


  1. 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.

  2. 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
