Our systems development process: “V” diagram

The fundamental process that we apply to all systems engineering activities is the “V – model”. More commonly known as the “Validation & Verification” or simply “V&V” model. The V model is used throughout the Aerospace industry in various forms (ie. SAE ARP 4754).

Detailed application of the ‘V-model’ can vary between organisations but fundamentally the same process is followed. WEC takes pride in the ability as ‘System Integrators’ to work across most areas of the ‘V-model’ from the initial requirements capture through to final verification.

TOP-DOWN REQUIREMENTS DEVELOPMENT, DESIGN & VALIDATION

BOTTOM-UP DESIGN & REQUIREMENTS VERIFICATION

1Platform Validation

“Derive validated top-level requirements in response to the perceived need.”

Top-level requirements are typically driven by the client reacting to a basic need. Whatever that need may be, an aircraft, a building or a district heating system, the ‘V-model’ is versatile enough to be applied to any project. WEC is practiced in working alongside the client to capture and distil their real needs and translate them into robust, validated top-level requirements.

2System Validation

“Establish validated system level requirements in response to the flow down of top-level requirements.”

Top-level requirements are distilled to derive system level requirements. This phase of design is more detailed and typically involves trade studies, system performance analysis and formal preliminary system safety analysis. WEC has many years of experience driving client designs forward using trade studies and various modelling and simulation techniques. The validation of system level requirements provides further opportunity to confirm that top-level requirements are being met.

3Sub System Validation

“Establish validated sub-system level requirements in response to the flow down of system level requirements.”

Use of sub-systems enable the development of large or complex designs to be broken down into more manageable activities. Detailed design is undertaken seeking to establish the necessary architecture, the required sub-system performance and the sizing of key parameters, all underpinned by integrated safety activities. Validation of the sub-system requirements provides a further opportunity to confirm that the system level requirements are met.

4Equipment Level Validation

“Establish validated equipment level requirements in response to the flow down of system or sub-system level requirements.”

Once the design architecture and key parameters are understood, requirements for components that realise the design can be established. This requires close working relationships between the systems integrator and the equipment supplier and is a key interface supported by control and specification documentation. At this stage the equipment supplier can begin design activities. WEC has many years of experience working alongside multi-national suppliers, performing management activities on behalf of clients.

5Equipment Level design

“Equipment and component design in response to the flow down of equipment level requirements.”

This is the domain of the equipment supplier and is the stage at which the equipment supplier can begin design activities. Significant collaboration with the system integrators is key as the design progresses to ensure that the intent of the equipment level requirements is appropriately captured. WEC has many years of experience working alongside multi-national equipment suppliers, performing supplier management activities on behalf of clients.

Platform Verification

“Confirm that compliance with top level requirements has been demonstrated.”

Verification of overall platform design can be started using various analysis tools and techniques once the requirements are validated. Such analysis cannot demonstrate complete verification and is typically used as risk mitigation. Empirical data is usually required to complete verification activities, this data will only be available following system verification. Formal reports and dossiers are prepared capturing all evidence and used to verify that all platform requirements have been met.

System Verification

“Confirm that compliance with system level requirements has been demonstrated.”

Verification of system design can be started using various analysis tools and techniques once the requirements are validated. Such analysis cannot demonstrate complete verification and is typically used as risk mitigation. Empirical data is usually required to complete verification activities, this data will only be available following sub-system verification. Formal reports and dossiers are prepared capturing all evidence and used to verify that all system requirements have been met.

Sub System Verification

“Confirm that compliance with sub-system level requirements has been demonstrated.”

Verification of sub-system design can be started using various analysis tools and techniques once the requirements are validated. Such analysis though cannot demonstrate complete verification and is typically used as risk mitigation. Empirical data is usually required to complete verification activities, with this data only being available post equipment verification. Formal reports and dossiers are prepared capturing all evidence and used to verify that all sub-system requirements have been met.

Equipment Verification

“Confirm that compliance with equipment level requirements has been demonstrated.”

Verification of equipment compliance to specified requirements is critical to ensure a robust design and to support final certification. WEC has significant knowledge and experience supporting clients and suppliers alike in interpreting qualification evidence and optimising its use to demonstrate compliance with imposed requirements whether it be via analysis, similarity or test.

Equipment Level Qualification

“Establish means of demonstrating compliance with equipment level requirements.”

This is the domain of the equipment supplier but with significant collaboration with the system integrators to ensure that proposed qualification activities are valid with respect to any imposed control or specification requirements. This represents the beginning of the verification activities which support eventual qualification and certification. WEC has many years of experience working alongside multi-national equipment suppliers, performing supplier management activities on behalf of clients.
