What this trail covers

Hex has evolved its data science capabilities by introducing a framework for assessing and improving data science maturity through a governance lens. This includes defining stages of maturity, providing diagnostic tools to assess current standing across dimensions like prediction access controls, metric definition consistency, AI output inspectability, and decision coverage. It also outlines a stage-by-stage roadmap for implementing governance, starting with documentation and endorsement, progressing to automated policy enforcement and continuous monitoring.

May 2026Data science maturity: stages, assessment, and roadmapThis post details a framework for assessing and improving data science maturity through a governance lens. It defines stages of maturity (Ad Hoc, Managed, Defined, Optimized), provides diagnostic exercises across four dimensions (prediction access controls, metric definition consistency, AI output inspectability, decision coverage), and outlines a stage-by-stage roadmap for implementing governance. The roadmap includes steps like documenting and endorsing data assets, centralizing metric definitions, implementing role-based access controls and workspace-level change policies, building full semantic layers, and establishing observability and auditability. The post emphasizes that trust and verifiability are key measures of maturity, especially with the rise of AI.
Feb 2026Building Trust in AI Analytics: Strategies for Data TeamsThis post details strategies for building trust in AI analytics by grounding them in governed data, making them explainable, and fostering organizational trust over time. Key strategies include centralizing governance around the data warehouse, implementing continuous validation, designing circuit breakers for uncertain outputs, and treating escalations as learning opportunities. Explainability is achieved by matching detail to audience, being transparent about uncertainty, and building progressive disclosure into interfaces. The evolution emphasizes that trust is a design problem, not an afterthought, and requires integrating governance, monitoring, and human review processes.
Feb 2026Enterprise data governance framework: components, roles, and AI readinessThis post details the components, roles, and AI readiness of an enterprise data governance framework. It emphasizes the importance of clear ownership, automation, and embedding governance into workflows. The post outlines core policies for data access, classification, retention, and privacy, and explains how semantic layers make these policies executable, especially for AI analytics. It also discusses centralized, federated, and hybrid governance models, and the roles of executive sponsors, data governance leads, councils, owners, and stewards. The impact of AI on governance is discussed, highlighting how AI can surface inconsistencies and how agents can aid in governance tasks.
Jan 2026AI & data analytics governance best practicesThis post details how to build governance that works for analytics and AI without blocking the work that matters. It covers LLM and generative AI governance, the business case for investment, regulatory frameworks (EU AI Act, NIST AI RMF, ISO 42001), operating models (centralized, federated, hybrid), and best practices for policies and controls including quality standards for AI inputs and access management. It emphasizes the need for clear accountability, transparency, systematic bias detection, protection of data and models, complete documentation trails, and meaningful human oversight over automated decisions. The post also highlights the risks of shadow AI and the importance of treating AI-generated content as a distinct data category with its own quality checks, lineage tracking, and approval workflows.
Jan 2026What is a data maturity model? Frameworks, Stages & TipsThis post details the concept of data maturity models, their importance, and outlines a five-stage progression (Initial/ad hoc, Emerging, Defined, Managed, Optimized). It emphasizes the role of data governance, technology, people, and culture in achieving maturity, particularly in the context of AI adoption. The post also provides guidance on how to assess current data maturity using frameworks like DAMA DMBOK, focusing on evaluating governance, technology, and culture.

Jan 2026Enterprise AI Governance Framework for Data TeamsThis post details an enterprise AI governance framework for data teams, focusing on accountability, transparency, fairness, privacy, security, and proportionality. It outlines seven pillars for building this framework: organizational structure, strategic principles, policies and standards, lifecycle management, identity and access controls, testing and validation, and monitoring and auditing. It also discusses the regulatory landscape (EU AI Act, NIST AI RMF, ISO/IEC 42001:2023) and provides a roadmap for implementation, emphasizing enabling AI adoption rather than blocking it. It specifically addresses governing agentic and autonomous AI by highlighting the need for scoped permissions and kill switches.
Aug 2025Data governance framework: key components and best practicesThis post details a framework for assessing and improving data science maturity through a governance lens. It defines stages of maturity and provides diagnostic tools to assess current standing across dimensions like prediction access controls, metric definition consistency, AI output inspectability, and decision coverage. It also outlines a stage-by-stage roadmap for implementing governance, starting with documentation and endorsement, progressing to automated controls and continuous monitoring.
Aug 2025Enterprise Data Governance: A Complete RoadmapThis post details a step-by-step roadmap for implementing enterprise data governance, focusing on defining a clear vision, establishing policies, rolling out in phases, and adopting collaborative technologies. It highlights common challenges such as stakeholder misalignment, data quality inconsistencies, and regulatory complexities. The post emphasizes the importance of clear roles and responsibilities, data standards and definitions, policy enforcement, appropriate technology, and continuous monitoring. It positions Hex as a tool that facilitates these governance goals by integrating with other platforms for lineage, documentation, and trusted metrics.
Aug 2025How Successful Enterprise Teams Do Data Governance: 10 Best PracticesThis post details 10 best practices for enterprise data governance, focusing on execution rather than awareness. It emphasizes balancing self-service analytics with security, classifying data by sensitivity (public, internal, confidential, restricted), enforcing data quality dimensions (accuracy, completeness, consistency, timeliness, validity, uniqueness) through standards and checks, adopting security by design principles throughout the data lifecycle, centralizing metadata management via tools like Secoda, automating governance processes for risk management and policy enforcement, conducting regular impact assessments for changes and policy updates, and building data literacy programs. It also touches on crisis management protocols and the importance of cross-functional committees.
Oct 2024Tony Avino: How HubSpot keeps data updated and trustedThis post details how HubSpot's analytics engineering team, managing product data for 8,000 employees, focuses on building data trust and communication. It outlines the four key elements of a data culture (leadership commitment, data literacy, tooling, accessibility) and the team's structure into 'Product core' and 'Product outcomes' groups. The post emphasizes treating data deliverables as products, measuring ROI through customer surveys (ENPS) and time-to-insight, and the analytics engineer's role in the data value chain (transforming raw data into usable marts). It discusses data lineage and governance challenges, the cost aspect of data warehousing, and the importance of process controls, peer reviews (CI/CD for data assets), and cost-performance considerations in data asset management.
