TOOLS
FOR RISKS MANAGEMENT
Summary
Although
Risk
Based Thinking is something new in the formal ISO 9001:2015. However, the concept has been the basis of Quality Management Systems since its inception in the US Military, and then brought into the civilian arena by the International Organization for Standardization (ISO
Standard).
The
base methodology for handling risks was also developed by the US Military in the
1950’s for reducing failures in equipment in the materiel. The core methodology
was and is called Failure Mode and Effects Analysis (FMEA). Initially it was used by Reliability Engineers but was
readily adopted by industries for improving Quality and Reliability.
In
the manufacturing arena, Quality Engineers use Process Failure Made and Effect
Analysis (PFMEA) version, while Design Engineers use the DFMEA version.
The
processes and tools are explained below. A demonstration of the system can be

Background:
Technically, Risk is defined as effect
of uncertainty on objectives. Risk Management is defined as an
organization’s response to a defined risk and management of its consequences. An
effect is a deviation from the expected positive and/or negative. We will
concern ourselves with only the negative effects of risk, and build systems to
avoid those that need to be avoided, and deal with escapes.
·
Risk Management can
be seen as consisting of the following
components:
o
Risk Assessment.
This consists of a systematic method for identification, analysis and
evaluation of risk:
§
Identifying a
Potential Failure Mode in a component of the Quality Management System, such as a work process or a result of the work
process, such as a product at various points of its’ life-cycle. Some people
just name this as the Risk Management.
§
The next step is
to identify the effect of the potential failure mode. Some call it the
Consequence. The Consequence needs to be given a score.
§
Failure Mode and Effects Analysis (FMEA). It is
common to identify potential cause(s) of the Failure Mode. This becomes useful
for refining the analysis, since the nature of the cause could affect ultimate
Effect (Consequence).
§
Corresponding to
the cause, current preventive controls are identified that should prevent the
risk from occurring.
§
A final step in
the analysis is to assign a measure of the Consequence
of the Risk Management, should it happen under current control mechanisms.
This RPN (Risk Priority Number) is
usually a product of the Consequence, times the (probability of) Occurrence, times the (difficulty of) Detection. Some companies use sum of
these metrics (S, O, D commonly remembered as SOD).
o
Risk Management This consists of Risk Assessment, Risk Prevention, Contingency
planning, and disseminating Lessons Learned.
§
Risks with high
RPNs need to be addressed.
§
Risk Prevention
consists of addressing the potential causes, by planning a Preventive Action,
which would change some aspects of the current system process(es), thereby
reducing the RPN from the unacceptable level to a level that is acceptable, or
tolerable.
§
The potential
causes could be removed, the likelihood reduced.
Tools
The following tools can be used for conducting the
various components
Risk
Assessment
Root Cause Analysis (RCA)
Local Prevention
Global Prevention
Management
of Change (MoC)
Conclusion
The
avoidance of risk has been the core motivator for the design of Quality
Management Systems and
Standards to facilitate same. The new ISO 9001:2015 has finally brought this to the forefront, with about
seventy five references to risk, risk management based thinking and
“opportunities”, a positive rendition of risk.
The
tools described above should assist the user to address risks, all the way from
identification to close out on a global basis. Students of Quality
Management Systems will
notice that the amalgam of the different tools can be considered to be a
complete treatment of the erstwhile Corrective and Preventive Actions in previous Quality Management Standards QMS. In
fact, some companies may elect to string the different components together to
produce a robust Corrective Action and Preventive Action!. The difference is that the concept of “Risk Based Thinking” encourages users
to think through what applies to particular circumstances and use the best
combination. For example, the chain of techniques could be aborted when
appropriate.
Risks
could be identified from Nonconformance, in which case the resultant
string would be a traditional Corrective Action. Risks that are forecasted (without Nonconformance)
would result in the traditional “Preventive Action”.
