Current challenges
Demand for new messages is growing

Current manually intensive message-by-message development approach cannot keep up with the growing demand for
industry standard messages, it is not fast enough



Same term has different meanings in different systems and standards
Multiple terms are used to describe the same concept in systems or standards
Lack of computer-readable industry reference for data definitions and their relationships
Can’t easily align/integrate standards with industries already adopting model-driven approach

For example, air traffic managers are investing heavily in the development of new information exchange models and
find it difficult to reflect in their models the concepts from established airline standards published in free text format.

Benefits
Increased consistency of definitions and format

Enforcing strong methodology ensures that all data is modeled according to the same rules. Concentrating all industry data
definitions in one repository accessible to all promotes re-use and increases the consistency of resulting standards.

Faster

of new
standards

2014
Re-using existing industry definitions, data and process models speeds up the development of new standards as well as
modifications of existing standards.
Streamlined deployment of new standards

Standards developed using the same methodology and the same data repository are consistent. Users need to learn only once
and then apply the same knowledge in multiple deployments..
Breaking down of silos

Integrated data model gives visibility across business areas and the possibility of re-use motivates the users to collaborate and
maintain common views and structure across business areas.
