Automated Testing and Documentation at G-SIB

Regulatory expectations and requirements have intensified over
recent years and model risk has taken centre stage on the
regulatory agenda. As a result, banks across the industry are
reconsidering their operating model and looking for ways to
increase efficiency and effectiveness across the end-to-end
model lifecycle.

In this case study, we look at how a Global Systemically
Important Bank (G-SIB) has implemented both the Chiron App
and Chiron Enterprise to support its modeling lifecycle and
model maintenance under evolving regulatory standards.


The bank is committed to practising effective Model Risk Management (MRM) by enforcing model risk policies that ensure full compliance with the SR11 guidelines for MRM.


Model documentation provided by model developers is often poorly written and inconsistent,
meaning it is inadequate to support a rigorous validation effort around the standards set by SR11-7.


Standardising the model lifecycle is challenging, given the multiple data sources and analytics libraries, the lack of standardised testing templates, and the strict documentation standards.

The Challenges

The bank was looking into enhancing the efficiency and effectiveness of its model development process.

Furthermore, the organisation was performing a model uplift to align its model documentation with internal/external minimum documentation standards, and wanted a strategic solution in place to streamline future uplifts through automated testing and documentation generation.

The Solution

Chiron App and Chiron Enterprise were deployed on-premise and integrated with the client’s enterprise risk systems and data stores to
leverage the golden sources within the organisation.

By enhancing the model lifecycle and introducing automated testing and documentation, the organisation achieved efficiency gains needed for model developers to re-focus on value-add activities.


All tests run on the platform can be replayed in the future with the data and model as they were originally run.


Models are tested at
scale through execution of standardised reusable
routines, which improves the efficiency, reliability
and speed of repeatable tasks and tests.


Automated generation of model documentation can be supported via predefined text blocks in 20% of the original time.


Integration allows
information like model name, model owner, legal entity, etc. to be consistently consumed within the client’s infrastructure.
