Building a Fraud Taxonomy: Shrinking MTTR with Incident Playbooks
Establishing a robust fraud taxonomy and incident response playbooks can significantly reduce mean-time-to-resolution (MTTR) for fraud incidents.
Fraud can cost you thousands; a structured response can save you even more.Back to all posts
## The $50K Hallucination Your AI model just hallucinated in production, resulting in $50K in customer refunds. This scenario isn’t just hypothetical; it’s a reality for many engineering leaders who underestimate the impact of fraud. As fraud tactics evolve, so must your response strategies. Without a clear taxonomy of
fraud types and a structured incident response, your team is left scrambling during a crisis, leading to increased MTTR and operational chaos.
## Why This Matters For engineering leaders, the stakes couldn't be higher. Fraud incidents can erode customer trust, lead to significant financial losses, and impact your brand’s reputation. A well-defined fraud taxonomy allows teams to categorize incidents effectively, ensuring that responses are timely and targeted.
Failing to implement these frameworks can result in missed signals and longer resolution times, costing your organization not just money, but credibility in the market.
## How to Implement It 1. **Define Your Fraud Signals**: Start by identifying key fraud signals such as capture anomalies, voice mismatches, and mismatch-to-ID scenarios. Document these signals clearly to guide your team. 2. **Create Decision Trees**: Develop decision trees that outline steps to take based on the fraud
signal type. This visual representation helps reviewers quickly categorize incidents and decide on the appropriate response. 3. **Develop Incident Playbooks**: Craft detailed runbooks that outline the steps for evidence handling, communication protocols, and escalation paths. Ensure that these playbooks are easily retr
ievable and user-friendly to reduce friction during high-stakes situations. 4. **Regular Training and Updates**: Conduct regular training sessions to keep your team informed about new fraud tactics and updates to your incident playbooks. This ensures that everyone is prepared to act swiftly and effectively when fraud
Key takeaways
- Establish a clear fraud taxonomy to identify and categorize fraud signals.

- Utilize decision trees to guide reviewers through complex fraud scenarios.
Implementation checklist
- Define specific fraud signals (e.g., capture anomalies, voice mismatches).
- Create decision trees for quick fraud categorization.
- Develop runbooks for evidence handling and reviewer ergonomics.
- Set up regular training sessions for teams on new fraud detection techniques.
Questions we hear from teams
- What is a fraud taxonomy?
- A fraud taxonomy is a structured framework that categorizes different types of fraud signals to aid in identification and response.
- How can incident playbooks reduce MTTR?
- Incident playbooks provide clear, step-by-step guidance for handling fraud incidents, which accelerates the response time and minimizes confusion.
- What are decision trees in the context of fraud detection?
- Decision trees are visual tools that outline the steps to take based on the type of fraud signal detected, helping teams make quick and informed decisions.
