In a highly regulated banking environment, collateral management and certification are critical processes to guarantee the compliance and reliability of financial operations.
Within this framework, a major corporate and investment bank initiated work to strengthen the traceability of application processes and to industrialize delivery and control mechanisms associated with applications related to collateral calculation and certification.
To secure these processes in a context of strong regulatory requirements, Avaliance supported the structuring of development, industrialization, and technical governance practices for the relevant applications.
Challenges
The client needed to strengthen regulatory compliance and the traceability of application processes related to collateral management.
The main challenges involved implementing industrialization mechanisms for delivery, improving development quality, and securing application deployments.
It was also necessary to facilitate the adoption of regulatory requirements by business and technical teams, while improving the reliability of collateral calculation and certification processes.
