Most data governance frameworks are designed for enterprises with 500+ employees, dedicated compliance teams, and six-figure software budgets. If you’re a mid-market company ($10M-$200M revenue, 50-500 employees), those frameworks are overkill — and trying to implement them will stall your data initiatives rather than accelerate them.

What mid-market companies need is a governance framework that’s lightweight enough to actually get adopted, but robust enough to solve real problems: inconsistent metrics, data quality issues, compliance risk, and the chaos that emerges when data grows faster than the processes managing it.
Here’s the framework I implement with my clients — battle-tested across SaaS, e-commerce, fintech, and marketplace businesses.
Why Mid-Market Companies Need a Different Approach
Enterprise data governance assumes you have dedicated data stewards, a Chief Data Officer, a governance council, and formal data classification workflows. Mid-market companies typically have none of these — and shouldn’t try to create them all at once.
The mid-market reality:
- Your “data team” is 1-5 people (possibly zero dedicated data staff)
- Data ownership is unclear — everyone and no one is responsible
- There are 3-4 different answers to “what was our revenue last quarter?”
- Compliance requirements exist but are managed reactively
- People use spreadsheets for everything the official tools can’t do
The right approach: start with the problems that hurt most, implement governance incrementally, and embed it into existing workflows rather than creating parallel processes.
The Four Pillars of Mid-Market Data Governance
Pillar 1: Metrics Dictionary (The Single Source of Truth)
This is where 80% of mid-market governance value comes from. A metrics dictionary is a single, authoritative document that defines every business metric your company uses.
For each metric, document:
| Field | Example |
|---|---|
| Metric Name | Monthly Recurring Revenue (MRR) |
| Definition | Sum of all active subscription revenue normalized to monthly amounts, excluding one-time fees |
| Calculation | SUM(subscription_amount) WHERE status = ‘active’ AND type != ‘one_time’ |
| Source System | Stripe (authoritative), replicated to data warehouse nightly |
| Owner | Finance team (CFO final authority) |
| Update Frequency | Daily in warehouse, monthly for board reporting |
| Known Limitations | Doesn’t include usage-based overages until invoiced |
Start with the 15-20 metrics your executive team references most. In my experience, these typically include: revenue (MRR/ARR), churn rate, CAC, LTV, pipeline value, conversion rates, NPS/CSAT, and 5-10 operational metrics specific to your business.
The process of creating this dictionary will surface disagreements you didn’t know existed. Good — those disagreements were silently causing bad decisions. Resolving them is the single highest-ROI governance activity.
Pillar 2: Data Ownership Model
Every data source needs an owner. Not a “committee” — an individual person who is accountable for the quality, completeness, and accessibility of that data.
The mid-market ownership model has three roles:
Data Owner (Business Side): A business leader who defines what the data should contain and how it should be used. They don’t write SQL — they set requirements and make decisions when conflicts arise. Example: VP of Sales owns CRM data quality.
Data Steward (Operational): The person who monitors data quality day-to-day and flags issues. In mid-market companies, this is often a senior analyst or ops person who adds data stewardship to their existing role (not a full-time position). Example: RevOps manager monitors CRM completeness and follows up on missing fields.
Data Engineer (Technical): The person responsible for the pipelines, transformations, and infrastructure that move and store the data. They implement the technical controls that enforce quality. Example: Data engineer builds validation checks in the ETL pipeline.
Practical implementation: Create a simple RACI matrix mapping each major data source to its owner, steward, and engineer. Post it where people can find it. Update it when roles change.
Pillar 3: Data Quality Framework
Data quality isn’t a project — it’s a continuous process. But the mid-market version doesn’t require expensive data quality tools. It requires three things:
1. Define quality dimensions that matter for your business:
- Completeness: Are required fields populated? (e.g., every deal in CRM has a close date)
- Accuracy: Does the data reflect reality? (e.g., revenue in warehouse matches Stripe)
- Timeliness: Is data fresh enough for the decisions it supports? (e.g., marketing dashboards updated daily, not weekly)
- Consistency: Does the same entity have the same attributes across systems? (e.g., customer name in CRM matches billing system)
2. Build automated quality checks:
If you’re using dbt (and you should be), implement data tests for every critical model:
- Not-null tests on required fields
- Uniqueness tests on primary keys
- Referential integrity tests between related tables
- Range tests on numeric fields (revenue > 0, percentages between 0 and 1)
- Freshness tests to alert when data stops flowing
3. Establish a quality SLA:
Define acceptable quality levels for each critical data source. Example: “CRM deal records must have >95% field completeness and be reconciled with billing within 24 hours.” When quality drops below the SLA, the data owner is responsible for remediation.
Pillar 4: Access & Security Policies
Mid-market companies typically oscillate between two extremes: everyone can see everything (risky) or access is so restricted that people can’t do their jobs (counterproductive). The right approach is role-based access with sensible defaults.
Three-tier access model:
| Tier | Who | Access Level | Examples |
|---|---|---|---|
| Open | All employees | Read access to aggregated business metrics | Revenue dashboards, product usage metrics, marketing performance |
| Restricted | Relevant teams + managers | Read access to detailed, non-PII data | Individual deal data (sales team), campaign details (marketing), support tickets (CS) |
| Confidential | Named individuals only | PII, financial details, compensation, legal | Customer PII, employee data, detailed financials, board materials |
Implementation: Map these tiers to groups in your data warehouse (BigQuery IAM roles, Snowflake roles, or Redshift groups). Review access quarterly. Remove access within 24 hours of role changes or departures.
For compliance-specific requirements (GDPR, SOC 2, HIPAA), layer additional controls on the confidential tier. But don’t let compliance requirements dictate your entire governance framework — that leads to over-restriction and shadow data.
Implementation Roadmap: 12-Week Plan
Don’t try to implement all four pillars simultaneously. Here’s the sequence that works:
Weeks 1-3: Metrics Dictionary
- Identify top 20 metrics through stakeholder interviews
- Document definitions, calculations, and sources
- Resolve disagreements (this will take most of the time)
- Publish and socialize the dictionary
Weeks 4-6: Data Ownership
- Map all data sources to owners
- Assign stewards for top 5 most-used sources
- Create RACI matrix and distribute
- Set up monthly data quality review meetings (30 min)
Weeks 7-10: Data Quality
- Implement automated tests for critical data models
- Define quality SLAs for top 5 data sources
- Build a simple quality dashboard (can be a dbt exposure or a simple Metabase dashboard)
- Establish incident response: who gets alerted, what’s the fix timeline
Weeks 11-12: Access & Security
- Audit current access across all data systems
- Implement three-tier model
- Document access request and review process
- Schedule quarterly access reviews
What Not to Do: Common Mid-Market Governance Mistakes
- Don’t buy a data catalog before you have data worth cataloging. Tools like Atlan and Alation are powerful, but they’re premature if you don’t have a data warehouse with organized models. Start with a Notion or Confluence page for your metrics dictionary
- Don’t create a data governance committee. Committees are where governance goes to die. Assign clear ownership and let individuals make decisions. Escalate only when owners can’t resolve conflicts
- Don’t write 50 pages of policy. Your governance documentation should fit on 5 pages. If it’s longer, no one will read it, and it won’t be followed
- Don’t try to govern all data at once. Start with the 5-10 data sources that drive business decisions. Expand governance as your data maturity grows. The rest can wait
- Don’t make governance a blocker. If people can’t get access to data they need within 24 hours, your governance is too heavy. The goal is to enable data use, not prevent it

How do you know your governance framework is working? Track these metrics:
- Metric disagreement frequency: How often do teams argue about “the right number”? Should decrease over time
- Data quality scores: Percentage of quality checks passing. Target: >95% for critical sources
- Time to data access: How long does it take a new employee to get the data they need? Should be <24 hours
- Data incident frequency: How often does bad data reach a dashboard or decision? Should decrease
- Self-service adoption: What percentage of data questions are answered without involving the data team? Should increase
Governance as Enabler, Not Bureaucracy
The best data governance is invisible. People don’t think about governance — they just trust their data, find what they need quickly, and know who to ask when something looks wrong. That’s the end state you’re building toward.
For mid-market companies, governance isn’t about compliance or control — it’s about building the trust in data that enables a data-driven culture. Without governance, every dashboard comes with an asterisk. With governance, data becomes the shared language of the business. And as AI becomes embedded in analytics and operations, governance extends to AI systems too — our AI strategy consulting includes AI-specific governance covering model access, prompt security, and output quality controls.
