Systems Assurance

An integrated, systematic, documented and pragmatic approach

systems assurance

At Acmena we work with your team to map, document and deliver a safe and successful system no matter how complex. We understand that projects require high levels of confidence to ensure a system will meet stringent safety, reliability, availability or maintainability requirements.

Our Approach

Acmena consultants have many years of experience in highly regulated, safety-critical industries such as Rail, Defence, and Nuclear. In these industries, customers not only have to achieve safety they have to document the evidence of how they got there. Successful systems assurance relies on:

  • Integrating assurance and risk management processes into the system lifecycle so that you maximise opportunities for making positive changes to design and operation
  • Being systematic to ensure you have identified all risks and are adequately controlling them
  • High quality documentation and smart information management so that you don’t drown in analysis and paperwork.

We provide the following services:

Safety Management

  • Acmena can provide safety and system assurance management services for your project, and we specialise in the safety management of technically complex, advanced signalling and train control projects (ETCS Level 1 and 2 and CBTC)
  • We can help you to develop or improve safety and system assurance management processes within your organisation
  • We can define and develop safety management processes which have at the core of their focus the way in which systems are used and maintained

Hazard Identification

  • We can plan, facilitate and document HAZOPs or other hazard identification workshops, with your key stakeholders and subject matter experts
  • Drawing on our experience, we can carry out desk-based hazard identification using techniques such as functional failure analysis (FFA) and review of our repository of published railway hazard and accident data

Hazard Analysis and Risk Assessment

We are able to perform qualitative and quantitative risk assessment using techniques such as Fault Tree Analysis (FTA), Failure Modes, Effects and (Criticality) Analysis (FME(C)A), Cause-Consequence Analysis and Interface Hazard Analysis.

RAMS Requirements and Risk Controls Capture

  • Using best practice requirements writing methods, we can document your system safety, reliability, availability and maintainability (RAMS) requirements and other risk control measures so they are consistent, unambiguous, and verifiable
  • We employ systematic methods to identify risk control measures to enable you to demonstrate you have reduced risk as low as reasonably practicable

Hazard and Risk Information Management

  • We can plan, design, establish and maintain hazard logs and risk registers to maximise their usability and effectiveness
  • We can implement your hazards logs and risk registers, including safety requirements and risk controls using a variety of templates
  • We can integrate your hazard logs and risks registers into your wider requirements or information management infrastructure based on tools such as DOORS, ComplyPro or similar

Safety in Design

  • We can help to ensure that risks are adequately controlled during the design process, so that the risk is not left to the operator to control, and document safety in design reports
  • We can develop processes to help organisations ensure they comply with Workplace Health and Safety legislation with regards to safety in design

Rail Safety Compliance

Whether you are a rail operator, infrastructure manager or supplier, we can help develop Safety Management Systems and procedures which comply with the legal requirements of Australian state and federal Rail Safety legislation.

Safety Standards Compliance

  • With extensive experience in the application of safety standards such as IEC 61508 and CENELEC standards 50126 (IEC 62278), 50128 (IEC 62279), 50129 (IEC 62425), we can provide advice on gaining cost-effective value from using these standards
  • We can audit or assess compliance against safety standards such as these above

Reliability and Availability Analysis

  • We can develop models to help predict reliability and availability
  • We can provide strategic advice on optimising the reliability or availability of critical functions of your products and systems, and achieving a satisfactory trade-off with safety

Independent Safety Audit and Assessment

  • We can provide peer review and audit of projects and product development, providing an independent assessment of the effectiveness of system assurance processes and the safety of the resulting system
  • We can audit and assess against the requirements of safety standards such as 50126 (IEC 62278), 50128 (IEC 62279), 50129 (IEC 62425)

Safety Case Development

  • We can produce clear, concise safety case documents, which help the reader understand the safety argument being made
  • We can help you to plan and structure safety arguments so that they are easy to follow and demonstrate, and actively help to deliver safer systems

Software Safety

  • We can help define software development and assurance processes which are compliant to IEC 61508 and CENELEC 50128
  • We can help develop strategies which focus on validating and verifying key safety requirements of software

Safety Incident Investigation and Management

  • We can provide a systematic approach to uncovering root causes of incidents and identify key recommendations
  • We can provide independent, objective assessments and help navigate sensitive issues around actions of personnel and safety culture

System and Safety Assurance Competency Assessment and Training

  • We can assess competency against IEC Competency Criteria for Safety-Related practitioners or similar criteria
  • We provide competency-based training courses on system safety
  • We can deliver tailored training and mentoring programs to develop your in-house capability
