Organized for efficiency. Using the powerful Action Wizard, each part of your
process breakdown is presented in a step-by-step format, making the iterative risk
assessment efficient for analysts at every level. The Wizard may even be customized
to provide for a high-level overview or detailed low-level analysis. |

Clear risk assessment. Relex Human Factors Risk Analysis software automatically
computes Risk Assessment Codes (RAC), or a risk score, for each identified
error. By the unique color-coding system, Relex Human Factors Risk Analysis
provides instant feedback to the analyst allowing for visual identification of
problem areas. The automatic criticality roll-up feature provides the analyst
with a high-level overview of high risk areas. |

Human errors account for an alarming rate of failures throughout a broad range
of industries worldwide. With high failure rates and the fact that the results of
human error can result in enormously costly failures, including the loss of life, the
need for human error analysis and safety assessment is crucial. Methodologies for
analyzing human error have been developed and adopted in several industries,
with NASA being a leader in this effort. Relex Software and NASA have worked
jointly to develop a software tool based on the NASA adopted methodology to aid
in the analysis of human error and corresponding risk assessment. The resulting
Relex
®
Human Factors Risk Analysis provides a comprehensive, systematic, and
streamlined approach to addressing this critical issue.
Proven methodology.
Relex Human Factors Risk Analysis is based on a HF-PFMEA (Human Factors
Process Failure Mode and Effects Analysis) approach. HF-PFMEAs can
be used to assess human safety and human reliability by analyzing
human processes or tasks and are a proven approach to reducing the
frequency and severity of human error.
Risk analytics. Analysis
begins with definition of process steps and the possible errors which
could occur. The analyst must then determine the effects of those
errors, as well as the associated severity and likelihood. Providing
a framework for this analysis, Relex Human Factors Risk Analysis computes
a Risk Assessment Code (RAC), or risk score, for each error. By color-coding
the RAC results, instant feedback is provided to identify problem
areas so that risk reduction techniques can then be effectively employed.
The Relex Architect platform.
Relex Human Factors Risk Analysis includes all the advanced features
of Relex Architect’s robust, proven framework. A rich user interface
is coupled with innovative features such as the invaluable Project
Navigator for centralized Project control, the Relex Bar for customized
one-click operations, the Task List for quick access to commonly used
tasks, and data filtering for ultimate user control of data views.
Comprehensive reporting capabilities include easy-to-use Report and
Graph Wizards for complete user customization of output reports and
graphs. Relex’s Import/Export Wizard enables you to transfer your
Project data to and from Relex in a variety of popular formats, including
Microsoft Excel ® and Access ® . Additionally, Relex Architect modules
are built on a common database, for optimal product integration and
data sharing capabilities.
Built for the enterprise.
Relex’s Enterprise Edition supports the high performance, scalable
needs of large user bases. Features such as support for Microsoft
SQL Server ® and Oracle ® databases, permission based security, user
and group roles, front end web interfaces, Relex Dashboard for a high-level
overview of system metrics, audit trails for tracking data modifications,
and customizable data connectors insure that Relex meets the needs
of full scale, enterprise-wide teams.
Organized framework.
Relex Human Factors Risk Analysis assists both the human factors novice
and expert in performing a comprehensive and systematic analysis of
human errors by providing an organized approach that significantly
improves consistency, efficiency, and thoroughness. In addition to
being able to enforce the cyclic review of high-risk errors, Relex
Human Factors Risk Analysis allows risk scores to be determined and
errors to be ranked based on these scores automatically. By cycling
through the process of adding barriers and controls and re-evaluating
risk scores, Relex Human Factors Risk Analysis offers a streamlined
approach to risk assessment and overall risk reduction. Usage of the
comprehensive database of suggested barriers and controls enables
the analyst to consider various risk reduction techniques. The complete
online help system was developed in conjunction with domain experts
in human risk analysis to offer guidance during all aspects of the
analysis process.
