Years after years, the number of partners involved in a product development increases significantly. As a result and because of tight project schedule and high quality constraints, solution to improve the relationship between stakeholders of the same company, JVs, tier 1 and 2 is becoming mandatory to avoid project deliveries delays and bad quality (misunderstanding, lost requirements...). Requirement-oriented document definition, with both standardized textual and/or graphical representations like SysML, is one of the best practices that appear for improving the communication and the exchange of specifications. Unfortunately even if requirement definition clarifies what the system shall do and speed up the commitment on system specification, the relationship, especially during specification negotiation and product delivery phases, is still time consuming due to heterogeneous processes and communication channels. In recent years, some standards have begun to emerge which support the systems engineering process. HIS, a joint standard initiative of the German automotive industry created RIF (Requirement Interchange Format) for component specification exchange between OEM and potential tier suppliers. This paper demonstrates two different solutions that have already been adopted by major companies of Automotive, Aerospace and Railway industries to automate such relationship with considerable cost-efficiencies, development time savings and quality improvements. It also introduces an innovative peer- to-peer solution upon this newly introduced RIF standard, based on an intelligent client and a light MySQL server allowing all the parties to share requirements from their original Requirement Management tool.
