iSys Integrity was established
by Dr Carl Sandom in 2003 to provide independent,
high quality and low overhead systems engineering consultancy services
specialising in Systems Safety Management and Human Factors Engineering
for large-scale software intensive systems.
iSys Integrity is highly adaptable
to clients' requirements in terms of contract structure and working arrangements,
and can readily provide whatever degree of on-site presence is required
by the client. iSys Integrity is also able to call upon associate consultants
to provide domain specific risk, safety and human factors specialist services
whenever this is necessary to fulfil client needs.
Capabilities
System
Safety Engineering
System risk is modelled by
linking the hazard causes using Fault Tree Analysis with the consequences
using Event Tree Analysis. Conducting systems risk assessments to identify
hazards and derive integrity targets is a core skill and iSys Integrity
has extensive experience of software safety assurance for real-time, high-integrity
systems.
iSys' fundamental philosophy
is that systems risk assessment activities must take technical, human
and organisational factors into account or system integrity cannot really
be assured.
This systems approach to risk
assessment has been successfully applied to several major human factors
and safety analyses for large-scale Defence Aviation and Air Traffic Management
systems. The same approach can equally be applied to any high-integrity
system to assure financial, mission-critical or safety-critical functionality
and thereby reduce system risk to a specified tolerable level.
Safety Management
Fundamental safety management
activities that iSys Integrity can provide assistance with are:
Specification and implementation
of Safety Management Systems
Production of Safety
Management Manuals
Other project specific safety
activities that iSys Integrity can provide assistance with include:
Formulation of cost
effective Safety Programme Plans
Responding to ITT safety
requirements and producing bid enhancing documentation
Development of auditable
System and Software Safety Cases
Conducting Preliminary
Hazard Analyses to identify and quantify key safety and programme
risks
Conducting System
Hazard Analyses to refine and extend the preliminary analysis
Designing and maintaining
a Hazard Log tailored to project specific needs
Occupational Health
Hazard Analyses
Performing Independent
Safety Advisor or Auditor (ISA) roles
Human Factors Engineering
Human factors are often cited
as both hazard initiators and hazard mitigators within high-integrity
systems analyses. If human factors risks are not considered fully a system
may not achieve its true level of integrity. If human factors mitigations
are not considered the system technical components may be over engineered
at additional cost.
Typically, over 90% of the
causal factors of hazards in complex systems are attributable to human
failures. iSys Integrity possesses a unique combination of systems engineering
and human factors expertise to undertake comprehensive human factors analyses
for high-integrity systems. The use of specialist HF techniques and methods
can be brought to bear for the specification of human subsystem requirements
to preserve high system integrity.
Key benefits of the iSys Integrity
approach to Human Factors analyses include:
Hazard-related focus
rather than a broad and costly approach
Systematic and scaleable
approach to human safety requirements specification
Maximum reuse of systems
engineering analyses
