Customer Project manager

The Customer (in particular Agency) project manager must keep control on cost, schedule, and risk. He is not technically concerned with the interface standardization, although he is a consumer of the SAVOIR technology. He relies on technical staff (his system engineer) who will be the one to actually write specifications and reuse the Savoir Reference Specifications, instead of reusing the specification of the last project he was working for.

The project manager will value in SAVOIR the existence of proven products with high TRL and standard interface functionalities, the availability of several vendors (multivendor policy) and interoperability.

For a Customer project manager, it is important to have a common vision of the system architecture and required interface in phase A and B1. This avoids suppliers to deviate from the standards. But the involvement of the suppliers is needed: they must be ready and able to perform a smooth migration to product lines through innovation without revolution. In addition, standards must be done at the right level of interface, without “micro standardization”, i.e. standardizing at a functional level is likely to be more efficient than standardizing at a very detailed physical level.

System integrator

The system integrator project manager needs to release his constraints by being able to reuse existing building blocks at the right level of TRL, fitting the requirements, meeting schedule and cost. This reduces his risks. But this is only possible if his customer is flexible enough (open minded) to accept a design solution based on the reuse of Savoir building blocks, and therefore on the reuse of the Savoir specifications.

On the other hand, system integrator's strategy should also not impose the systematic reuse of existing building blocks, because it might not always reach the goal of reducing budget and risks. This may happen when the organization includes product policy entities whose outputs are enforced on projects by management. The product policy people are therefore also important stakeholders of Savoir.

Equipment supplier

The equipment suppliers aim at reducing the cost of the equipment. Their customers often require the same functions, but they all specify it in a different way, with different design constraints, such that the notion of product line cannot be implemented. The customer ITT process must be improved at satellite and unit level. Savoir provides tools and links between the suppliers and the system integrators.
