ARP4754 A Brief Introduction
SAE ARP4754 A is becoming the standard in terms of systems engineering
Certification authorities are imposing compliance with ARP4754 A to OEMs, prime systems suppliers and to main sub-tiers
Appendix A of ARP4754 A lists the main objectives to be met, along with the key artefacts.
Objectives pertain to the main activities and processes making a typical Product Development life cycle.
These include:
- Planning (ARP4754 A Objectives 1.1 and 1.2)
- Concept definition
- Requirement capture and validation (ARP4754 A Objectives 2.1; 2.3; 2.4; 3.7; 4.1 to 4.5)
- Design and Implementation ( ARP4754 A Objectives 2.2; 2.5; 2.6; 3.7)
- Integration and verification (ARP4754 A Objectives 2.7; 5.1 to 5.6)
- Safety Assessment (ARP4754 A Objectives 3.1 to 3.7; 5.4)
- Certification (Objectives Objective 8.1)
- Supporting processes, also called ‘’integral’’ processes because the span across the entire Product Development life cycle:
- Project Management (*)
- Risk Management (*)
- Configuration Management (ARP4754 A Objectives 5.6; 6.1 to 6.4)
- Process Assurance (ARP4754 A 7.1 and 7.2)
- Requirement Management (ARP4754 A Objectives 2.1; 2.2; 2.3; 2.4; 2.6)
(*): project management and risk management are not explicitly stated in ARP4754 A but are key parts of developing a product
Associate deliverables include:
- Plans and standards:
- Development Plan (ARP4754 A Sections 5.8.1 and 5.8.4.1)
- Safety Program Plan (ARP4754 A Sections 3.1; 5.1.5 and Appendix B)
- Validation Plan (ARP4754 A Sections 5.4.2 a and 5.4.7.1)
- Verification Plan (ARP4754 A Sections 5.5.31 and 5.5.5.1)
- Integration Plan (*)
- Configuration Management Plan (ARP4754 A Section 5.6.2.1)
- Process Assurance Plan (ARP4754 A Section 5.7.2)
- Requirement Management Plan (*)
- Requirement Definition and Validation Standards (*)
- Design Standards (*)
- Build and Integration Standards (*)
- Verification Standards (*)
- Configuration Management standards (*)
- Process Assurance Standards (*)
(*): the integration plan, the requirement management plan and the standards are not explicitly called in ARP4754 A, yet they can be valuable instruments in the success of the product development.
