Savoir Banner

Producing documents

The documents are produced through industrial activities. They are reviewed by SAG, then by selected ESA project teams. They can then enter a wider public review in industry, before being published.

Document review Process

A collaboration with the ECSS organisation and Eurospace allows to organise efficiently these wider industrial consultations

Using documents

The Prime contractor prepares his own documents such as the System Requirement Specification, the ICDs, some high level software Requirement Baseline, etc.

Use of SAVOIR documents

Then the Prime prepares the Product Specifications for the procurement for the hardware (CDMS specs, unit specs) and for the software (Application specification, execution platform specification). The SAVOIR documents are intended to support this activity, by allowing the Prime to reuse product specifications for his own procurement. This is when the Primeís avionics architect envisages a physical architecture and maps the Savoir functional architecture on the physical units that he intends to procure, tuning the configuration parameters of the generic specification to actual projectís values.
