With the increasing reliance on models and complex analytics in financial services and other industries, model risk has become a crucial issue that must be managed properly. Implementing an effective model risk management framework is essential for organizations to identify, measure, monitor, and control risks associated with the use of models.
This article overviews model risk management and key steps for implementing a robust model risk framework.
Part 1: What is Model Risk Management?
Models carry inherent risks that must be managed. Flaws in how a model is designed, built, or used can lead to harmful outcomes when decisions rely on that model's outputs. To mitigate model risk, organizations should have robust processes for model inventory, risk assessment, control implementation, performance monitoring, and issue escalation. Effective model risk management helps ensure models are sound, used properly, and their limitations are well understood - reducing the chance of unintended consequences.
The goal is to ensure models are sound and used appropriately to drive good decisions and avoid losses.
Part 2: Types of Model Risk
Various forms of model risk exist, such as:
- Model design errors: Flaws in how the model is designed, such as incorrect assumptions or mathematical errors.
- Data errors: Issues with data inputs, such as incomplete, inaccurate, or inadequate data.
- Implementation errors: Bugs or errors in model coding or configuration.
- Use of model beyond its intended purpose: Using a model for something it wasn't designed for.
- Misinterpretation of model outputs: When users do not properly understand model outputs.
- Lack of model monitoring: Failure to check that the model remains suitable over time.
- Unexpected behavior: Models behaving erratically or producing errant outputs under certain conditions.
Part 3: Key Components in Model Risk Management Framework
An effective model risk management framework contains several core components:
- Model inventory: Register all models used by the organization with info like use cases, owners, data inputs, etc.
- Model development standards: Model design, testing, documentation, controls, etc.
- Model validation: Review of model methodologies, inputs, outputs, etc. to identify flaws.
- Model governance: Policies and procedures for model approval, implementation, monitoring, use cases, control, etc.
- Model performance monitoring: Ongoing checks on model performance and stability.
- Use case assessment: Evaluation of appropriate use cases for each model.
- Reporting: Regular reporting to senior management and regulators on model risk exposure.
Part 4: Best Strategies for Implementing Model Risk Management
To successfully implement model risk management, organizations should follow these key strategies:
- Get executive buy-in: Ensure senior leadership supports MRM initiatives.
- Take inventory: Identify all existing models and their uses.
- Prioritize models: Focus efforts on models with the highest potential risk.
- Assess comprehensively: Review all aspects of high-risk models methodology, data, coding, outputs, etc.
- Validate models: Perform initial and periodic validations using subject matter experts.
- Document thoroughly: Require extensive documentation for model development and applications.
- Match models to use cases: Ensure models are only applied to appropriate uses.
- Monitor continuously: Perform ongoing monitoring of model performance and stability.
- Control access and changes: Manage model access and require approvals for changes.
- Report regularly: Provide regular reporting on model risks to senior leaders.
- Update framework: Continuously improve policies and controls based on new risks.

Conclusion
Model risk is a growing concern as complexity increases in financial services and other industries. Developing a robust model risk management strategy is crucial to govern model use and mitigate threats posed by faulty or misused models. By instituting model inventories, validation procedures, monitoring, and controls, organizations can effectively identify, measure, and manage model risk to support sound decisions and avoid losses.
The right model risk management framework paired with versatile tools like EdrawMax enables organizations to reap the benefits of models while protecting against associated risks.
