Foundation

iSys Integrity Limited 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

 

Training

iSys Integrity have experience of undertaking Training Needs Analyses as well as course design and delivery in:

      • Safety Management Systems
      • Human Factors
      • Systems Engineering

iSys Integrity also offers a introductory one-day 'Human Factors and Systems Safety' training course aimed at Senior Systems Engineers and Programme Managers to provide valuable and pragmatic advice on maximizing value from targeted human factors analyses.

Benefits

Specific benefits to the client arising from the services provided by iSys Integrity include the following:

      • Highly competitive rates due to low overheads
      • Seamless integration of safety management and human factors into other management processes and project lifecycles
      • Better understanding and control of supplier safety management aspects
      • Enhancement of safety management capability
      • Assured safety management support through the whole lifecycle
      • Maximised returned value from safety consultancy contract
