Automated Testing and Documentation at G-SIB


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 Yields’ Model Risk Management platform to support its modelling lifecycle and model maintenance under evolving regulatory standards.


The bank is committed to practising effective MRM by enforcing model risk policies that ensure full compliance with the SR11-7 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.


Standardizing the model lifecycle is challenging, given the multiple data sources and analytics libraries, the lack of standardized 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 organization 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

Our MRM platform was 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 organization achieved the 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 the execution of standardized 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.

The Yields Advantage provides an end-to-end Model Risk Management platform to automate MRM activities and reduce model risk. The platform consists of two technologies: Chiron App & Chiron Enterprise.

Chiron Enterprise is a customizable model inventory and workflow management tool that streamlines the execution of end-to-end Model Risk Management processes.

Chiron App is a modular data science platform that automates all quantitative model testing and documentation.
