In several previous issues we've discussed the
need for internal auditors to properly prepare for audits. But
just what exactly does that mean? How does one go about preparing?
How much time should be dedicated, and who can afford to take the
time necessary for proper internal audit preparation? These
questions are often asked by participants in internal auditing
classes. They are as valid as they are common. The answers are not
as easy as the questions.
Internal audit preparation requirements are
based on many factors. The size of the organization, the
complexity of the audited processes and skills and abilities of
the auditor all play an important role in how much preparation is
needed. Probably the largest variable in determining preparation
time is the amount of resources that can be committed to the
audit.
Preparation, in order to be effective must
occur as several levels.
-
Organizational level
-
Standards level
-
Auditing level
The auditor must be prepared for auditing at
each level if the audit is expected to be successful. The method
used to prepare for each level is different, as is the time needed
to prepare. Let's look at each in greater detail.
Organizational Level
At this level the internal auditor must have a
working knowledge of the processes used throughout the
organization. In order to properly audit a process, the auditor
needs to have some base information about the process. This
includes the process inputs and outputs, and the materials and
resources necessary for proper process function. Without this
information, the auditor will not be able to determine if the
process is functioning
The best method of preparing at the
organizational level is to begin at the "big picture"
level. Understand your organization's mission, customers and
product lines. A SIPOC diagram is a great way to look at your
organization at a macro level. SIPOC stands for: Supplier (who do
you purchase/acquire what from?); Input (what inputs, such as
material, information, resources, etc. are needed for the
organization to operate?); Process (what does your organization
do?); Output (what is generated by your process?); Customer (who
buys the output of your process?). By identifying the parts of the
SIPOC, the auditor can have a better feel for how the organization
operates.
In many cases, the auditor must look deeper
than the big picture. Audits are focused on specific processes,
and the internal auditor must have a certain amount of working
knowledge of those processes in order to ask meaningful questions
and identify what evidence will need to be collected to show
evidence of conformance.
In multi-location organizations, internal
auditors may be required to gain a sense of the processes of other
locations. This is usually more difficult than single-location
organizations because the auditor typically have minimal contact
with other locations. Coordination through the Management
Representative will undoubtedly be required in order to meet the
needs of auditor preparation.
Standards Level
The auditor must be aware of the requirements
of the standard. Knowing how to interpret the standard is vital in
determining whether situations are conforming or not, even though
most internal audits rely more on the organization's documentation
than the standard. The auditor must still know and understand what
the standard is trying to achieve and what evidence would show
that the letter and the intent of the standard is being met.
The best method of achieving this level of
audit preparation is to thoroughly digest the standard. Know what
it says, as well as any supporting documentation (such as ISO
9004). Reading trade journals, publications (such as Internal-Auditor.com)
and even books on the subject are good methods of increasing
knowledge of the standard.
Auditing Level
One of the key requirements for effective QMS
internal auditing is for the auditor to have auditing skills. The
three main skills are:
-
Time management
-
Fact finding
-
Reporting
Although much of audit level preparation is
based on growing experience, there are still things the internal
auditor can and must do prior to each audit. Preparing the audit
plan and determining/developing an adequate checklist can be real
time-savers during the audit. When determining the audit schedule,
attempt to make the audit flow, to prevent continual walking from
end of the facility to the other. Sequence the audit based on
location, rather than the standard. If you are auditing based on
processes, then the process flow should be of help here. If it is
not, then you might want to raise the issue of whether the
organization needs to investigate lean manufacturing (office)!
The checklist also helps outline your
fact-finding strategies. On the checklist, the internal auditor
annotates what evidence they are seeking, how many of which
records to examine and what questions to ask. Knowing the
checklist questions prior to the audit is crucial in maintaining
credibility and conducting an effective audit.
The audit checklist can be used to determine
who you are going to ask questions to, what you will be asking and
what other evidence you are seeking. As you develop the checklist,
consider how much time to dedicate to each question/examination
and try to predict time needs and check them against the proposed
schedule. The audit scope and sample size may have to be adjusted
in order to fit within the time constraints.
Even audit reporting requires some preparation.
Which forms are used, if any, what will the reporting format be
and how the report will be presented must all be pre-planned.
Typically, the auditor's role in reporting is minimal, however the
auditor must be prepared to perform their role in the reporting
plan.
A significant part of audit level preparation
is to review previous audit results. From this inform, the auditor
gains valuable insight on what items are critical and what items
are trivial. This allows the auditor much more flexibility during
the audit and will result in closer adherence to the audit scope.
Summary:
A properly prepared auditor will find auditing
to easier, less problematic and more effective. The audits will
contain less stress, have less conflict and more efficient. Audit
preparation eliminates frustration on both the auditor and the
auditee. It increases the credibility of the audit and the
auditor.
It is the internal auditor's responsibility to
ensure there is sufficient preparation for the audit. It is the
Management Representative's responsibility to ensure the auditor
has sufficient time and other resources required to be adequately
prepared for conducting the audit. Neither of these can occur
without the commitment and blessing of top management. Auditors
cannot be expected to be prepared with only minutes to prepare
prior to the audit.
One last thing. The auditee may also need some
time for audit preparation, although not as much as the auditor.
The auditee will need to make sure all records are available at
the time of the audit (some organizations keep all records
off-site). The auditee may also have to ensure personnel key to
process operation are available on the day and time of the audit.
The auditee must also make plans to keep interruptions and
distractions at a minimum (auditors also need to do this.)
