In a large scale Financial Transformation project for a major insurance company group, affecting more than 80 daughter companies and hundreds of legal entities, AVANT is used to manage the business requirements and validate the technical implementation. It provides an “end2end” view on the delivery of financial and insurance information up to their use in reporting. The business requirements are mapped into the insurance “Information Object Model” from which the technical implementation is derived. This offers the unique possibility to validate and ensure the completeness, correctness and coherence of the implementation.
