Assurance is a set of structured and planned activities conducted through the asset life cycle providing progressive justified confidence that objectives are being achieved and that the asset is or will be fit for purpose
The Elements of Assurance
| 10
Assurance layers
1st Level Assurance
2nd Level Assurance
3rd Level Assurance
Engineering process, assurance process, risk
management etc.
Auditing, independent reviews, independent
validation, ISA
Project and TfNSW audits, reviews, due diligence and
acceptance

The Elements of Assurance
| 12
Assurance and the Asset Life Cycle
| 13
Demand / Need PhaseLifecycle Phase Activities and Accountabilities Assurance Requirements
Demand / Need
• TfNSW triggers change based on: Input from its Operators or Maintainers
• by strategy or external factors e.g. population growth, urban development etc.
• Assure the identified trigger for change is justified
• Key decisions must be risk based and assured
• Alignment with TfNSW business objectives and strategy –authorisation audits
| 14
Plan PhaseLifecycle Phase Activities and Accountabilities Assurance Requirements
Plan
Strategic decision making by TfNSW in identifying and evaluating options to meet the demand / need aligned with• Long term transport strategy• Meeting transport demand needs and
other objectives e.g. urban regeneration and development
• asset management strategy
TfNSW decides on selected option, develops and specifies it
AEOs provide technical advice and support to TfNSW
Assure that the right asset is specified, i.e. specify what is needed to meet the intended demand need
Consider safety in an auditable and assured manner balancing it with other risks and opportunities.
Demonstrate that selected and specified option is that which best ensures safety so far as is reasonably practicable (SFAIRP)AEO technical capability assured through their authorisation scope –authorisation audits
| 15
Acquire PhaseLifecycle Phase Activities and Accountabilities Assurance Requirements
Acquire
AEOs deliver assets and associated assurance to TfNSW compliant with TfNSW standards and contracts.
Engineering decisions generally made by AEOs.
TfNSW manages delivery and conducts appropriate governance and due diligence
Extensive Engagement with Operators and Maintainers
AEOs assure the assets they are providing for their intended operation and intended life – includes safety, RAM, whole of life cost and fitness for purposeTfNSW implements governance and due diligence based on level of riskIndependent safety assessment conducted for higher risk new or altered assetsConfiguration management gateways ensure appropriate progressive assurance through CCBs and CMAACAEO technical capability assured through their authorisation scope
| 16
Operate / Maintain PhaseLifecycle Phase Activities and Accountabilities Assurance Requirements
Operate / Maintain
Contracted Operator and Maintainer Operate and Maintain Transport Network Assets in line with TfNSW standards, requirements and contract.
Operator and maintainer provide asset condition information and assurance back to TfNSW
TfNSW monitors asset conditions.
Approves annual maintenance budgets and plans
Condition and performance monitoring by maintainersDevelopment and assurance of annual maintenance plans by MaintainersConfiguration management gateway 6 monitors maintenance strategy and planningOperator and maintainer manages TfNSW’s asset risks including safety through appropriate assurance processes and arrangementsMaintainers are AEOs whose technical capability assured through their authorisation scope – authorisationaudits

An Assured Transport NetworkThrough whole of life the transport assets / system must be assured as:
• Reliable• Safe• Operable• Maintainable• Sustainable• Optimised whole of life cost• Fit for purpose
| 20
System Safety is the concurrent application of systems based approach to safety engineering and of a risk management strategy covering the identification and analysis of hazards and the elimination, control or management of those hazards throughout the life cycle of a system or asset• Legislative requirements drive safety• Integrate safety into design and delivery of assets and systems• Delivered by AEOs• Independent Safety Assessment framework has been developed• Progressive assurance across lifecycle• Human Factors• Scalable assurance process
System Safety Assurance
| 21
Systems engineering is central to the assurance frameworkAnalyses complex requirements form many stakeholders to achieve efficient outcomesIntegration is key as part of assuring transport assets and systems
• Integration into network• Integration of complex systems• Integration of assurance across the lifecycle
Systems engineering in TfNSW is a process based engineering approach that flows from concept and requirements, through design, development, installation, testing and commissioning, to operation and maintenance and finally to decommissioning and disposal

Configuration Management, CMAAC and CCBs

AEOs assure their engineering activitiesAssets and systems delivered to TfNSW are fully assuredAEO assessed and authorised against their capability to deliver assured outcomesASA conducts ongoing risk based audit of AEOs
Authorised Engineering Organisation Model
| 24
Standards are a key element of an asset assurance argument
The ASA assures its standards through:• Scalable assurance process• Risk controls from standard linked to network risk• SFAIRP justification for standards• Assurance argument for novel or high risk content• Standards span engineering, assurance, human factors, asset
management, systems engineering• Industry consultation
Assured Standards
| 25
TfNSW Safety Management System
| 26
ASA TfNSW:• has established a multi-element assurance framework that is safety
focused and supports the assurance of transport assets throughout the asset life cycle
• the framework is growing in maturity but is comprehensive and driving improved asset management and performance outcomes
• the desired outcome is that TfNSW safely plans, builds and manages safe assets to provide services to move people and goods across NSW
