GEIA-STD-927 specifies the data concepts to be exchanged to share product information pertaining to a complex system from the viewpoints of multiple disciplines. It supports the exchange of data across the entire life cycle for the product from the concept stage through disposal. It embraces several aspects:

• technical aspects that lead to the definition of functional and physical architectures (what the system is doing, how it is doing it and how well);

• technical management (work schedule, document generation, concurrent engineering, validation, and verification procedures);

• project aspects that include project management issues (traceability management, configuration management, and trade-off analysis);

• industrial management (management of co-operation between partners).

The following discipline views are within the scope of GEIA-STD-927:

• definition of other systems that the system interacts with;

• context for the system in each life cycle phase;

• support of hierarchical break down modeling techniques;

• functional and non-functional requirements of the system in each life cycle phase;

• definition of the static and dynamic behavior of the system;

• configuration management of the system and its supporting documentation in each life cycle phase;

• condition monitoring and correction of the system.

The following life cycle aspects are within the scope of GEIA-STD-927:

• systems engineering;

• feasibility assessment;

• requirements definition;

• domain engineering;

• system realization;

• system operation;

• system support;

• system maintenance;

• decommissioning of the system.

The following types of data are within the scope of GEIA-STD-927:

• data to describe the system; data to specify requirements of the system and their allocation to functional objects, physical objects, and the physical implementation;

• data to specify the static behavior of the system in terms of functions and flows between functions;

• data to specify dynamic behavior of the system;

• data to describe the functional decomposition of the system;

• data to support the physical architecture;

• data to support the partitioning of the system;

• data to support the verification and validation of the system;

• data to specify the installation of the equipment, including physical locations and information;

• data about the shape of the equipment data to support project and industrial management;

• data to support the documentation of the system data to support configuration management;

• data used in domain engineering;

•data used in feasibility assessment;

• data used in system realization;

•data used in and for system operation;

• data used for system maintenance;

• data used for decommissioning of the system.
