IVTV

    IVTV means Integration Verification Transition and Validation. It is a plan developed and validated during the design step (see picture below) in order to check if the design matches with customer requirements. All stakeholders can refer to this document to see if design models are aligned with the customer's vision and the forecast. This document is also a way to insure a good transmission between teams, activities and processes concerning system design and system realization.

To explain what represent IVTV we can go through each terms:

• Integration: the purpose is to prepare the system of interest (SOI) for final validation, transition and for production.
• Verification: the verification process aims to ensure that the system will be built accordingly with customer requirements and will be validated with an acceptable level of risk.
• Transition: the goal is to ensure that all subsystems can be implemented together or all the interfaces needs are taking into account and managed.
• Validation: the validation process aims to ensure that the system satisfies the customer and user needs as stated and agreed and ready to be qualified or exploited.

In the IVTV document you will find all these informations:

• Description of the project
• Relevant documentation
• Abbreviations
• Description of the context: perimeter, constraints, requirements, parameters of the system to be checked
• Strategy: general principles, actions for integration, verification, transition and validation and schedule of these actions
• Organization and responsibilities: description of the team, human resources involved, way of working between teams
• Tools and practical resources (building, warehouse, test bench…)
• Planning of the design and the production of the system

    It is key to start the IVTV plan as soon as possible. The more early you start the IVTV the more efficient it will be. It is also very important that it is made by other workers to have new points of view. Thanks to this plan we can prove that the design match with the customer requirements. We also minimize the risk of discrepancies between the product and its design.

A good IVTV is obtained after a lot of iterations. A good communication between the different design department and the verification team is also one of the key aspect to ensure an efficient IVTV.
