The Elements of Assurance
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

Demand / Need Phase
Lifecycle Phase Activities and Accountabilities Assurance Requirements
• Assure the identified trigger for change is justified • TfNSW triggers change based on: Input
from its Operators or Maintainers • Key decisions must be risk based Demand / and assured • by strategy or external factors e.g. Need
population growth, urban development • Alignment with TfNSW business etc. objectives and strategy – authorisation audits
| 14
Plan Phase
Lifecycle Phase Activities and Accountabilities Assurance Requirements
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 Plan • 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 Phase
Lifecycle 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 purpose TfNSW implements governance and due diligence based on level of risk Independent safety assessment conducted for higher risk new or altered assets Configuration management gateways ensure appropriate progressive assurance trough CCBs and CMAAC AEO technical capability assured through their authorisation scope
| 16
Operate / Maintain Phase
Lifecycle 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 maintainers Development and assurance of annual maintenance plans by Maintainers Configuration management gateway 6 monitors maintenance strategy and planning Operator and maintainer manages TfNSW’s asset risks including safety through appropriate assurance processes and arrangements Maintainers are AEOs whose technical capability assured through their authorisation scope – authorisation audits

Dispose Phase Disposal is treated as a change in its own right following the life cycle

An Assured Transport Network Through 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 Assurance 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
| 21
Systems Engineering Systems engineering is central to the assurance framework Analyses complex requirements form many stakeholders to achieve efficient outcomes Integration 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 f lows from concept and requirements, through design, development, installation, testing and commissioning, to operation and maintenance and finally to decommissioning and disposal

Authorised Engineering Organisation Model AEOs assure their engineering activities Assets and systems delivered to TfNSW are fully assured AEO assessed and authorised against their capability to deliver assured outcomes ASA conducts ongoing risk based audit of AEOs
| 24
Assured Standards 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

TfNSW Safety Management System
| 26
Conclusion 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
