Governance for GenAI: The Minimalist Blueprint That Actually Scales

By Digvijay Waghela, Senior Data Architect at Chewy

Forget the slow-moving steering committees and the hundred-page policy documents gathering digital dust. If you’re leading a GenAI initiative, you’ve felt the tension: the urgent business demand to ship against the nagging worry about what could go wrong. The reality in enterprise technology today is that teams don’t fail because the model isn’t smart enough; they fail because governance is an afterthought—bolted on too late, scattered across too many teams, or treated as a compliance checkbox instead of a core engineering requirement. 

In my experience building and scaling AI-powered platforms serving millions of users, I’ve seen this dichotomy firsthand. The path to production is littered with two extremes: the reckless ship-it-now pilot that security shuts down, and the paralyzed governance-first program that kills momentum. There is a better way. 

This article proposes a Minimum Viable Governance mindset. It’s a practical, engineering-led blueprint built around five foundational controls. This isn’t about slowing innovation; it’s about creating the guardrails that let you accelerate safely, measure what matters, and iterate on security as rigorously as you do on model performance. 

Adopt the Minimum Viable Governance Mindset  

Think of governance like a feature. It must be enforceable, observable, and owned. If you can’t enforce it in code, observe it in logs, or assign an owner to maintain it, it’s paperwork, not governance. 

A governable GenAI system allows you to answer three critical questions for any interaction: 

  • What could it see? (Data Access) 
  • What was it allowed to do? (Policy Boundaries) 
  • Can we reconstruct what happened? (Auditability)

Start by mapping your system to a simple four-layer model—Data, Retrieval, Model, and Application. Governance isn’t a monolith; it’s a set of targeted controls applied at each layer to contain risk before it becomes an incident. 

The Five Controls: High-Leverage, Manageable Overhead 

Control One: Establish Least-Privilege Access.  

A common and critical mistake is treating a generative AI system as a privileged super-user with unfettered access to corporate data. The correct approach is to view the AI as just another user. Your first line of defense is to enforce existing row-level or document-level security directly at the data source, ensuring the system only pulls from pools of information it is explicitly permitted to see. 

However, the crucial reinforcement happens at the retrieval layer: you must apply a final security filter based on the identity of the end-user making the request, not the service account of the application itself. This enforces a simple, unbreakable rule that prevents most data disasters: if a person cannot access a document, email, or record through a standard company system, they absolutely cannot access it through an AI chatbot. This control transforms a potential data exfiltration endpoint into a securely managed channel. 

Control Two: Mandate Proactive Data Hygiene.  

Many teams exhaust themselves trying to build filters that catch sensitive information in the AI’s live output—a reactive and often unreliable safety net. The higher-leverage strategy is to prevent restricted data from ever becoming retrievable. This starts with implementing an automated ingestion pipeline that classifies all incoming content using a straightforward scheme—such as Public, Internal, Confidential, and Restricted—that everyone in the organization can understand. 

Before any document is indexed for AI retrieval, this gate must detect and redact common PII patterns, payment information, credentials, and other sensitive data. For optimal safety and simplicity, maintain separate vector indexes for different classification levels. This fundamental shift—from catching sensitive data on the way out to stopping it at the door—is far more effective and reliable. 

Control Three: Deploy Runtime Guardrails.  

Even with perfect access controls and clean data, an AI model can still generate unsafe, non-compliant, or entirely fabricated content. Runtime guardrails act as the essential policy enforcement engine at the precise moment of use. This involves standardizing a clear list of allowed and disallowed behaviors; for example, summarize this contract may be permitted, while provide legal advice on this clause is explicitly blocked. 

It also means restricting which external tools or APIs the model is allowed to call. One of the most pragmatic rules you can implement is a grounding check: if the system cannot retrieve credible, supporting sources to substantiate an answer, it must default to a I don’t know response or ask a clarifying question, rather than guessing with false confidence. This single rule dramatically reduces the confident nonsense that erodes user trust in enterprise deployments. 

Control Four: Build an Immutable AI Ledger. 

Inevitably, a question will arise: Why did the AI say that? If you cannot answer definitively, you are not operating a production system. Comprehensive traceability is non-negotiable. For every interaction, you must log an immutable chain of evidence: the user’s identity and context, a hash of the exact prompt used, the specific document IDs that were retrieved, details of the model and its parameters. 

You must also log the final output, and a record of any guardrail decisions that were triggered. This AI Ledger turns post-incident panic into a straightforward forensic query. It is the foundational capability that enables meaningful audits, rapid incident response, and continuous, data-driven improvement of your entire system. 

Control Five: Apply Targeted Human Review.  

The mistake is believing human oversight must be applied to every output, creating an impossible bottleneck. The solution is to apply human judgment as a precision instrument only where consequences are severe. Clearly define high-risk scenarios in plain language: customer-facing decisions that influence purchases, any financial, legal, or medical content. 

Also define outputs containing sensitive personal information, or actions that change a system of record, like issuing a refund. For these specific workflows, design patterns like draft-only modes, where the AI proposes and a human finalizes, or mandatory approval gates before external delivery. Build seamless, one-click escalation paths for users and moderators. Done correctly, human review becomes a scalable control that manages your greatest risks without stifling overall velocity. 

The Operating Model: Owners, Not Committees 

Governance fails when accountability is collective and therefore absent. You don’t need a large, slow-moving committee; you need clear, single-threaded ownership. Assign these four roles explicitly to eliminate ambiguity and accelerate decision-making. This structure replaces organizational confusion with direct responsibility. 

First, Domain or Data Owners are responsible for content accuracy and classification. The Platform Team owns the technical enforcement and logging infrastructure. The Product Owner defines use cases and escalation paths. Finally, Security and Privacy teams set data policy and audit requirements. When these roles are clearly defined, the blame game vanishes. 

Measure to Improve: The Governance Dashboard 

You cannot manage what you do not measure. To prove your governance works and guide its evolution, track a concise dashboard of metrics. Focus on three key categories: Risk, Quality, and Operations. This data transforms governance from a theoretical exercise into a manageable system. 

Monitor Risk through blocked request counts and sensitive data retrieval attempts. Gauge Quality with grounded-answer rates and user corrections. Watch Operations via system latency and log completeness. Review these monthly and treat improvements like a product backlog—prioritize, deliver, and measure impact. 

Conclusion: Ship Fast, Ship Safe 

The goal of minimalist governance is to unlock velocity, not hinder it. By implementing these five controls—access, hygiene, guardrails, traceability, and targeted review—you build a foundational layer of trust. This trust is your license to innovate. It satisfies security stakeholders, assures business leaders, and protects end-users. 

In the race to implement GenAI, the winners won’t be those who move fastest out of the gate, but those who build the systems to run safely at scale. Start with these minimal controls, iterate relentlessly, and turn governance from a perceived roadblock into your greatest accelerator.
