Study Notes
- The Verification process checks the correct implementation of system requirements, architectural characteristics, and design properties during system integration.
- The Validation process may be invoked to ensure individual system elements meet stakeholder requirements and provide intended function.
- System integration includes the preparation for and performance of integrating system elements, managing interface availability and addressing issues, and controlling outputs.
- Prepare for integration involves establishing checkpoints for interface implementation, strategy/approach identification, and planning for enabling systems or services.
- Perform integration involves integrating system element configurations until the system is complete, managing interface availability, and performing checks of interfaces, functions, and critical quality characteristics.
- Manage results of integration involves capturing integration results, identifying inconsistencies, and using the Project Assessment and Control process to identify root causes, take corrective actions, and record lessons learned.
- Maintain bidirectional traceability of integrated system elements with strategy, plans, and requirements using the Configuration Management process.
- The integration strategy should account for the availability of system elements, personnel, and consistency with fault isolation practices.
- Development of integration enablers, such as tools and facilities, can take as long as the system itself and should be started early in the project.
- Integration process of complex systems should use flexible approaches and techniques, integrate aggregates in order to detect faults more easily, and apply the coupling matrix technique for fault isolation.
- Integration occurs throughout the project from initial needs identification to utilization and support, with the focus evolving from system definition to deployed and operational system integration.
