Total quality management
is a commitment to the continuous improvement of work processes with the goal
of satisfying internal and external customers.
It’s the customer that matters in TQM; the process is only the means to
satisfying the customer.

ustomers are only satisfied if their requirements are
consistently met. To be competitive, we
must meet these requirements in a timely and cost effective manner. TQM provides the organizational focus and
mind set, as well as specific tools and techniques, to ensure meeting customer
requirements, first time and every time.
A key principle of TQM is intense focus on customers and
their satisfaction. What does this mean
and how do we go about accomplishing it?
We can use three principles in creating this focus.
Customer Focus
First, I.S. must identify, measure and "design
in" the product and service attributes that the customer cares about. How do we know what these attributes
are? As a start, we can certainly ask
the customer. However, this is only a
start. Organizations which have become
adept at TQM are able to go well beyond asking the customer to anticipating the
future needs and desires of their customers.
Second,
we must continually monitor customer satisfaction. The only determination of "quality" that really matters
is the customer's perception. Customer
feedback and participation in the process is essential. Formal and continuous monitoring will keep
the organization focused.
Third,
management must make sure that everybody knows their customers, both internal
and external. Further, it is essential
that everybody can "see" the ultimate customer using their products
and services. Employees at all levels
of the organization should be given opportunities to observe the customer using
their products and services. All
employees should understand how each process used in producing products and
services adds value for the customer.
If
these three principles are understood and applied at all levels of the
organization, the customer focus will be pervasive.
Levels of Customer Satisfaction
Customers, both internal and external, have basic
requirements which must be satisfied if they are going to do business with your
organization. These represent the
absolute minimum that must be done.
Beyond
that, customers have expectations, both expressed and implied, that must be met
if they are going to desire to continue to do business with you.
Top
notch, or "world class" organizations, delight their customers by
consistently exceeding both requirements and expectations. This then becomes a continuous process as
each level of performance creates higher expectations.
It is
extremely gratifying and rewarding to be associated with an organization that
consistently delights its customers.
Applying TQM To Information Systems
To successfully apply TQM to I.S., we must concentrate
on three things:
·
Identify all our
customers, both internal and external.
·
Define customer
requirements and expectations.
·
Deliver information
products and services which meet, or exceed, defined requirements.
Who is the
Customer?
Customers
for an information system are many and varied.
They include, of course, those individuals who directly use the system
to perform their work tasks. These are
the "users," and are normally easy to identify. For example, clerks in the Personnel and
Accounting departments are users of a Payroll System. For TQM purposes, all users are customers.
Those
in management who authorize, request, budget and approve information systems
are customers. Without their participation,
there would be no systems work to perform.
These individuals are most often different from the users of the
system. Many levels of management may
need to review and approve the decision to implement a new Payroll System, and
while they may never interact directly with the system, they certainly have
requirements.
Many
customers may receive outputs from an information system. These are indirect customers, and they may
have very specific requirements.
Employees receive their paychecks from a Payroll System. Government agencies have requirements for a
Payroll System, as do banks, auditors and providers of employee benefits, to
name just a few.
Those
individuals who must operate and maintain a system are also customers and have
specific requirements. These are
internal customers whose requirements must be met if they, in turn, are to meet
the requirements of their customers.
The computer operator must be able to accurately print paychecks and
payroll reports if the requirements of users and employees are to be met. Likewise, the maintenance programmer must be
able to implement necessary changes over time if the Payroll System is to
continue to meet the needs of other customers.
For
most systems, the organization's external customers are at least indirect, and
increasingly direct, customers.
Strategic systems and systems which have direct external customer
interface, such as Electronic Data Interchange (EDI) in Purchasing or Order
Processing, impact the external customer.
Vendors of information systems and services constantly interact directly
with external customers.
The I.
S. organization must be thorough in identifying all potential customers for an
information system if they are to have any possible chance of meeting customer
requirements.
What Are The
Customer's Requirements?
This is
the area which often presents an insurmountable hurdle to implementing TQM in
Information Systems. Defining customer
requirements is usually the most difficult task we face.
How can
I. S. professionals be expected to meet customer requirements, first time and
every time, when no one, including the customers, knows exactly what these
requirements are? Many systems
development professionals believe that TQM simply cannot apply to them. They never develop exactly the same system
twice. They believe that "Zero
Defects" is totally unrealistic.
I once
had a sincere Programmer/Analyst tell me:
"You never know what the user's requirements are until you get into
the testing phase, so the thing to do is code something and see what
happens."
Fortunately,
TQM offers tools and techniques which can be used in conjunction with sound
systems analysis work to assist us in properly and completely defining customer
requirements.
How Do We Ensure
That Requirements, Once Known, Can Be Met?
The only method which produces quality information systems on a
consistent basis is a "Life Cycle" approach. In our last column we discussed those
stable, measurable, repeatable processes which must be in place to ensure
quality in systems development and maintenance. Lacking these processes, meeting customer requirements is a pure
crap shoot. Sometimes we will win, but
more often we will fail. Worse, there
is no way to predict what the result will be on our next project.
Defining Customer Requirements
Why are information systems requirements so difficult to
define? Why do documented requirements
often turn out to be not even close to defining the system which ultimately
gets implemented?
There
are two major reasons why requirements definition is so difficult. First, the customer/user may have only the
vaguest idea of what an information system should look like prior to actual
implementation and use of that system.
Second, system developers commonly lack sufficient knowledge of the
business functions a system must support to define how the system must be
configured.
This
dilemma is usually addressed by developing systems which automate the
organization's currently existing manual processes.
The
problem with this approach is that automation of manual processes does not add
significant value nor make use of the greater capabilities of information
technology. Worse, where manual
processes do not exist or are poorly understood by the users, systems efforts
commonly fail to produce usable results.
This historical approach to systems development goes a long way to
explaining the need for the massive reengineering projects we see in many
organizations - finally we are beginning to truly leverage information systems
to improve business processes.
Requirements
definition is so important and so difficult.
How can we make this process easier and less error prone?
Know Your Markets
Organizations with mature TQM functions have become
proficient at satisfying and delighting customers. They invest a great deal of effort in learning about their
customers. They work with customers on
joint problem solving teams. They
participate with customers in product design and development. They conduct extensive surveys. They have excellent intelligence about their
competitors. They are aware of their
customers' strategic direction.
You
cannot invest too much time in learning about your customers and the
business. Information Systems
organizations have been too isolated from the mainstream of the business
enterprises they serve. I. S.
management cannot be concerned primarily with technology if they are to meet
customer requirements.
Obtain Theoretical
Business Knowledge
In his
book, Rethinking Systems Analysis and
Design (Boston: Little, Brown and
Company, 1982), Gerald Weinberg talks about the time it takes someone who knows
nothing about a field to amass knowledge comparable to that of an entry level
graduate student in that field. The
period is somewhere between one to three months.
You
can't develop good inventory management systems if you don't know inventory
management. You can't develop good
accounts payable systems without a knowledge of accounting.
Do not
assume that your customers/users possess this theoretical knowledge. As W. Edwards Deming, the most famous of the
quality gurus, has said, "Experience teaches nothing unless studied with
the aid of theory." It is very often
sad and dismaying to encounter the absence of even basic theoretical knowledge
among practitioners about the business functions they are involved in every day
of their working lives.
Study Existing Systems
Use
existing systems as a starting point in developing requirements for a new
system. Analyze the system to be
replaced, but also include other systems.
These may be systems you have worked with in the past, systems available
from vendors, systems used by competitors.
The best analysts can see similarities between systems used for
different business purposes and extrapolate these to apply to the existing
environment.
Analyze The Using Environment.
The most logical
and complete method for obtaining requirements is from a complete analysis of
the environment within which the system must be used. Observation of this environment, and, if possible, actual working
experience in the environment will be invaluable in developing information
requirements. However, this is true
only if the analyst comes to this task armed with sufficient knowledge of the business,
theoretical understanding of the business functions and familiarity with
existing systems (as described in the preceding paragraphs).
Interview Customers/Users.
The
junior analyst typically begins by asking the customer/user what is
wanted. Analysis very often stops at
this point. In 1975, I delivered a
speech at an Information Systems Conference where I discussed promoting
Programmers to Analyst positions. I used
an example of the Analyst who was proud to be able to code the solution before
anyone had defined the problem.
Interviews
should not take the course of asking customers what they want. They should be used to mutually define
problems and opportunities for information technology application. Discuss problems with users. Clarify issues which were identified in
observing the environment. Make
suggestions and observations based on theoretical knowledge and familiarity
with other systems. Get users to talk
about their jobs – the challenges and opportunities of their business functions. Interviews should therefore take place well
into the requirements development process.
Prototyping.
Prototyping
seems to be all the rage just now. It
can be the latest and greatest way of avoiding the previously described
analytical work, allowing the Analyst/Computer Technician to work more with the
computer than with the business functions.
Tools, techniques and methodologies are always very poor substitutes for
business knowledge during requirements definition. This is true of Structured Analysis, Rapid Analysis, JAD, as well
as prototyping.
Prototyping
is most useful in an environment where no one knows the answer. Where a model does not exist for a system,
where theoretical knowledge is lacking (because for whatever reason it is
unobtainable) or where the environment in which the system must operate cannot
be observed (because presumably it does not yet exist), the analyst, in
conjunction with the customer, must fall back on an iterative approach to
information systems requirements definition.
Always
be aware that early attempts are likely to miss the mark. Don't be dismayed by repeated failures and
throwaways. After all, you are sailing
in uncharted waters. If this weren't
true, you wouldn't need to do the prototyping.
We are
fortunate to have software tools available that allow us to build prototypes
and mock ups quickly and relatively inexpensively, thereby supposedly avoiding
the expensive systems development fiascoes we have built in the past. However, two cautionary notes in using prototyping.
First,
just because you can prototype something doesn't mean you can build it. Last year, I worked on TQM principles with a
software firm that introduced a prototype in 1989. Customers went wild. This
was totally new, it would revolutionize a whole segment of their business.
The
software firm budgeted one year and $1 million to turn the prototype into a
working system. Three years and almost
$4 million later, they still had not delivered a satisfactory system. The firm lacked the system development
methodologies to ensure that they could develop quality systems once they had a
defined prototype.
Second,
resist the prevalent trend to use prototyping as a substitute for business
knowledge, analysis of existing systems, analysis of the business environment
and user interviews. Prototyping is a
fall back position in requirements definition, not the answer in and of
itself. Sure, to the computer
technologist, prototyping is a lot more fun than studying inventory management,
accounting, production control or other business functions. Maybe we should consider others for the job
of requirements definition.
Summary - How TQM Can Help
TQM tools and techniques can be invaluable in the
analyst's arsenal when developing information systems requirements.
TQM
provides a basis for a common language in problem definition and problem
solving. Concentration on elimination
of root causes of problems and on such TQM concepts and team building,
empowerment and continuous process improvement can ensure that information
systems address the "true" customer requirements rather than slap a
band aid on symptoms of problems. These
TQM tools are tremendously powerful in getting all parties to focus on the
requirements of the business and its ultimate customers.
When
applied within the Information Systems function, TQM can help the organization
maintain the focus necessary to ensure that systems, as developed, meet
customer requirements first time and every time. Continuous process improvement, constant feedback, elimination of
the cause of errors make the process visible and responsive. Work which is not directed at meeting
customer requirements can be identified early in the systems development
process and corrective action can be initiated.
Applying
TQM to the system development process can produce immediate and dramatic
dividends. Start by identify all your
customers. Then ensure that customer
requirements are completely defined, understood and agreed upon. The process of developing systems which meet
customer requirements will not be easy, but it can only be undertaken once we
know what those requirements are.
TQM is
not a program or a methodology. It is a
philosophy of doing business.
Fortunately, TQM also provides enabling tools and techniques which, when
consistently applied, ensure that Information Systems organizations can meet customer requirements - first time and
every time. n
