Weasel Words
The ISO9000 Quality Standards were developed by the
international quality community through the International
Organization for Standardization (ISO TAG176). In the development
process, any wording perceived as restricting trade or
prescriptive was eliminated through the consensus vote process
used by ISO TAG176. That is why the Standard uses ambiguous terms
like "the supplier", "as appropriate",
"defined intervals", "timely", and
"consideration." This language is used in the Standard
to establish what is to be done without telling how to do it.
At times, this may create a dilemma. One company has said,
"Defining these requirements will tie us to things we may
not always be able to do. We want to make ambiguous statements so
we can operate freely." The use of ambiguous wording in
procedures or work instructions is sometimes called "weasel
words" and do not clearly describe what is to be done.
The use of weasel words results in a two-fold problem. If the
requirements are not clearly defined, the people performing these
activities will not know what to do. Additionally, auditors will
not be able to determine if the system is in compliance during an
audit.
Whenever possible, clearly define the ambiguous terms used by
the Standard when writing procedures or work instructions. These
documents tell auditors and people within the company the who,
what, when, where, and how to do their jobs. After using clearly
defined terms, it may be discovered that they are too
restrictive. If this is the case, change the procedure or work
instruction through the document control system to more
accurately describe the activity. Effective use of the document
control system is a sign of continuous improvement.
There are times when it is appropriate to soften well-defined
terms. For example, in ISO9001 requires the performance of
management reviews "at defined intervals" must be
addressed. Care must be used when choosing the wording in order
not to be tripped up by creating unnecessary restrictions.
Stating that management review will be performed
"quarterly" could be viewed as four times per year on a
ninety day cycle. While the intent to define the interval for
management review as "quarterly" is good, the ability
to consistently hold a documented management review every ninety
days may be difficult. By softening the interval for management
to "at least annually," once a year or more is
acceptable. If for some reason an intended quarterly management
review was not performed, the quality system would still be in
compliance.
