IVVQ stakes ●
Qualify the system in relation to the “true” need.
●
Check the system for conformity with the contractual commitments.
●
Contribute to the reduction of risks and optimisation of the cost/lead time performance.
Synthetic definition of the IVVQ process ●
SE process repeatedly implying all key actors and used for verifying/validating the needs, requirements, solutions and products throughout the life cycle.
IVVQ success factors ●
Identify as soon as possible (from the invitation to tenders) the efforts and managers necessary for the IVVQ process.
●
Generate the IVVQ plan as early as the start of the life cycle knowing how to use the IVVQ feedback of former projects.
●
Apply and enrich the IVVQ plan for each activity of the SE.
●
Identify and control the IVVQ-inherent risks as early as the start of the project.
●
Organise and Systematise the IVVQ reviews with all project actors.
●
Capitalise the IVVQ feedback.

Definitions Integration Assembly and test operations - during development or manufacture - used to check that the construction of a product, or of a system, on the basis of its components is carried out in accordance with the data generated by the design.
System qualification Decision made by the acquirer after an operating period showing that the true need is met and used to reliably launch the mass production. (IVVQ Working Group definition)
(IVVQ Working Group definition)
System verification Confirmation, by inspection and objective evidence, that the requirements specified […] are met. (EIA 632 definition)
System validation Confirmation, by inspection and objective evidence, that the provisional specific use of the end product […] is performed in a planned operational environment. (EIA 632 definition)
Deliverable product verifications: necessary operations to check that the products of the N subprocess meet its own objectives, are consistent with the output data of N-1 sub-process and provide for the correct achievement of all the next sub-processes.

The “System Qualification” process is not standardised for the time being: its comprehension varies
according to the fields of activities. The above representation illustrates the vision of the IVVQ working group.
