The main benefits of developing common and shared target architecture are:
- Consistency of the definition of the ATM systems and their interfaces easing their inter-operability.
- Reduced complexity and ambiguity in specification using the support of a model easing maintenance and evolutions.
- Reduced inconsistent terminology and commonly agreed and understood semantics through a common information architecture.
- Greater and easier use of industry standard for design methods and products leading to lower costs and reduced development risks for ATM/CNS industry and ultimately improving the time to market.
