Evaluation of Performance Measurement Systems
Measurement is done in organizations for various
purposes. The primary measurement system is usually the one that
results in Financial Statements such as Profit and Loss Statement
and Balance Sheet. While these are necessary and useful for the
purpose for which they are intended, their intended purpose is
primarily external to the management of the organization. They are
structured according to Generally Accepted Accounting Principles (GAAP)
and, often, have little relationship to meaningful performance
measurement. At best, they are too summarized to be useful and, at
worst, they provide a very limited and often misleading picture of
the performance of the organization. No examples need be given here
of organizations whose financial statements indicated successful
operation right up to the point when they had a drastic, and
seemingly spontaneous, change in fortunes. Thus, the less internal
people see and use financial statements to manage the business, the
better.
Brian Maskell, in Performance Measurement for
World Class Manufacturing, indicates several categories of
performance measurement in addition to financial measurement.
Among them are delivery performance, process time, production
flexibility and quality. Thus, any tool useful for evaluating or
auditing existing or proposed performance measurements must take
into account several factors:
• It must be able to statistically evaluate the
accuracy of the measure and any standard associated with it.
• It must identify and evaluate the need for a vector component of
the performance measure.
• It must be able to relate the indirect measure with the standard
or goal it attempts to motivate people to attain.
• It must be able to understand the intended behavioral consequences
of the performance measurement and anticipate unintended
consequences.
• It should evaluate each individual measure and measures in
related groups, since the behavioral result of measuring performance
with a group of measures is not the sum of the result of each
individual measure.
• It should evaluate the degree to which individual performance
measures and the performance measurement system fulfills Drucker's
eight requirements.
• It must be a continual process since the requirements of the
performance measurement system will change as the needs and goals of
the organization change in response to new markets, technologies,
cultures and organization structures. To this end, existing
performance measurement systems, in addition to being continuously
audited, should be subject to the admonition of Drucker to test
everything you do in an organization at least every three years
with the question "If we stopped doing this, what would happen?"
The mechanism for doing this starts with a clear
understanding of the goals of the organization and how these goals
are impacted by the activities of the various teams within the
organization. This step, along with all the other steps in this
process, cannot be accomplished by top management or financial
management in a vacuum. It requires participation and agreement
among all who will participate in measuring and being measured.
Next, the existing performance measures must be
analyzed against three factors. This must be done not only for
individual performance measures but for combinations of performance
measures. These three factors are:
• Their applicability to the agreed upon goals of
the organization.
• Their fulfillment of Drucker's eight requirements.
• Review of their characteristics of accuracy, directional
measurement and the consequences that will result from the use of
the performance measurement.
Although this seems like a difficult and
time-consuming process (It is!), much of this, such as the
understanding of organization goals, should and will be a part of
any major organizational change, and, thus, is not additional to
what is already happening within the organization. The basic purpose
here is to integrate the changing of the performance measurement
system into other changes already underway or contemplated.
In going through this process organizations will
find that many of the measures current being used are, at best, a
meaningless waste of resources and, at worst, counterproductive.
Even so, there will often be resistance to eliminating these
measures since 1) many managers have learned to manipulate them to
their own advantage, either for financial/promotional reward or as
excuses; and 2) many have substituted the use of these measures and
the resultant reward/punishment system for a true understanding of
the business process in which they are involved. Often those who
will be evaluating the measurement system are the very ones who
benefit most from its retention. It takes strong top management
leadership to insure that the performance measurement system focuses
on organization goals.
In summary, performance measurement systems must
replace individual performance measures that were implemented
because they relied on the only information available. These
systems must go far beyond financial measures and encompass all of
the characteristics that lead to a successful, goal oriented
organization. Those being measured must be key participants in the
process since the work they do (knowledge based work) cannot be
measured without their willing complicity. These systems must focus
on organizational effectiveness, not just functional efficiency. A
clear understanding of the behavioral consequences is necessary to
implement a successful performance measurement system. Finally,
performance measurement systems must remain fluid and changing with
the ever changing needs of organizations to motivate people to
accomplish their goals.
