SICCODE.com maintains a governed, auditable framework for managing SIC and NAICS classification data and related business attributes. This page documents the policies, controls, stewardship roles, and change workflows used to support classification accuracy, editorial neutrality, and compliance-ready traceability across datasets.

Key definitions used on this page

Data lineage
Documented trace of how a classification or mapping was derived, reviewed, versioned, and released.
Controlled interpretive update
A clarification to improve explainability (e.g., included/excluded activities) without changing the official code hierarchy.
Version identifier
A release label used to track when logic or records changed so results can be reproduced during audits or longitudinal analysis.
Exception handling
A documented process for resolving ambiguous cases (e.g., multi-activity firms) using consistent rules and reviewer oversight.

Purpose of Our Governance Framework

Governance provides the structure, accountability, and oversight required to maintain a trusted industry classification resource. It ensures that code assignments, mappings, and record attributes are validated, documented, and monitored under consistent standards. This includes alignment with official SIC and NAICS reference structures, as well as controlled handling of “common-usage” extensions and crosswalk logic where applicable.

This framework supports governance materials across SICCODE.com, including Our Classification Methodology, Verification Methodology, and About Our Business Data.

Reference-first positioning Governance pages are designed to be informational and policy-driven. Commercial services may exist on the site, but governance, methodology, and reference content are maintained under documented neutrality and disclosure standards. See Editorial & Neutrality Standards.

Governance Philosophy

The governance philosophy centers on accuracy, neutrality, transparency, and explainability. Governance is an active stewardship process: classification decisions must be evidence-supported, reproducible, and aligned to documented definitions—so organizations can rely on the outcomes in analysis, compliance workflows, and longitudinal research.

  • Accuracy: Classification decisions supported by evidence and validated against consistent rules and reference definitions.
  • Neutrality: Editorial and verification outcomes are not influenced by paid placements or external pressure.
  • Transparency: Changes carry lineage, version identifiers, and documented rationale.
  • Accountability: Defined stewardship roles own the process, review controls, and release quality.

Governance coverage matrix

This matrix summarizes where governance controls apply and what artifacts support auditability.

Area Governed Evidence artifact
SIC/NAICS code assignments ✔ Reviewer trace + rationale notes
Cross-system mappings (crosswalks) ✔ Mapping logic notes + validation checks
Controlled interpretive updates ✔ Change record + version identifier
Historical reproducibility ✔ Version archive + release notes
Editorial neutrality controls ✔ Neutrality & disclosure policy

Core Components of the Governance Framework

Policy & Oversight

Policies define how records are collected, verified, coded, and released. Oversight ensures alignment to defined standards and controlled handling of exceptions. See Data Sources & Verification Process.

Stewardship Roles

Data Stewards, Senior Reviewers, and Governance Leads maintain methodological consistency, classification quality, and compliance documentation. See Stewardship Roles & Accountability.

Auditability & Lineage

Records carry provenance, controlled versioning, and review traceability to support audit readiness and change accountability. See Data Lifecycle & Version Control.

Data lineage (at a glance)

A traceable chain from evidence to release. This is the core “audit handshake” used for reproducibility.

Step 1: Source evidence

Reference materials and record signals used to support classification logic.

Step 2: Classification logic

Rules applied consistently to assign codes and interpret edge cases.

Step 3: Steward review

Qualified review to confirm accuracy, neutrality, and evidence sufficiency.

Step 4: Versioned release

Controlled release labeled for historical reproducibility and change visibility.

Step 5: Audit log & archive

Trace artifacts retained to support audits and longitudinal comparability.

What this means: classification outputs can be traced back to evidence and reviewed logic, with versioned history for audits.

Governance hierarchy example

A simplified view of how controls and artifacts relate. This helps readers connect “lineage” and “change management” to tangible outputs.

  • Policy layer (standards + neutrality rules) → Policy documents
  • Method layer (how decisions are made) → Methodology + verification steps
  • Control layer (who approves / how changes move) → RACI + review checkpoints
  • Artifact layer (what an auditor can inspect) → Version ID + rationale + logs
  • Release layer (what users consume) → Published pages + datasets

Stewardship Structure (RACI Model)

Governance is operationalized through defined roles and responsibilities. The table below summarizes the stewardship model used to support ongoing classification accuracy and controlled release management.

Role Primary responsibilities Accountability
Data Stewards Validate SIC/NAICS assignments, maintain taxonomy definitions, and ensure mapping quality and consistency. Classification accuracy
Data Governance Lead Defines governance policy, quality standards, exception handling, and update protocols. Policy enforcement
Compliance & Audit Conducts audits, maintains lineage artifacts, and confirms regulatory alignment of stewardship controls. Governance integrity
Data Operations Manages ingestion, transformation, quality scoring, and release workflows under documented controls. Operational continuity

Key Governance Principles

  • Transparency: Code assignments and mapping logic are explainable and traceable.
  • Accountability: Stewardship roles maintain ownership of definitions, change controls, and release quality.
  • Security & Controls: Access control, versioning, and documented approvals protect integrity.
  • Compliance alignment: Governance controls support audit readiness for regulated use cases.

Change Management & Quality Control

Changes to SIC and NAICS mappings—such as reclassifications, definitional clarifications, or controlled interpretive updates—follow structured approval workflows designed to minimize errors and preserve traceability. Each proposed update undergoes:

  • Peer review by qualified analysts
  • Dual-source validation where applicable
  • Lineage logging and controlled version incrementing
  • Quality scoring prior to release

Versioning and release visibility are documented through the governance and methodology materials, including How It Works and Industry Classification Verification Framework.

Change workflow (at a glance)

A controlled path from change request to release, designed to preserve accuracy and auditability.

Step 1: Change request

Issue identified (e.g., ambiguity, revalidation trigger, mapping refinement).

Step 2: Peer review

Qualified reviewers evaluate evidence and apply consistent rules.

Step 3: Validation & scoring

Checks performed; quality scoring supports release readiness.

Step 4: Versioned release

Controlled publish with version identifier and change trace artifacts.

What this means: updates are controlled, review-driven, and versioned so stakeholders can reproduce results over time.

Governance Outputs

Organizations relying on SICCODE.com receive governance-backed deliverables such as:

  • Verified SIC & NAICS classifications with traceable lineage
  • Controlled version history suitable for compliance audits and reproducibility
  • Consistent mapping logic for analysis and cross-dataset interoperability
  • Neutral, evidence-based classification decisions supported by documented controls

Data Stewardship in Practice

Stewards monitor definitional guidance, reference updates, and market activity signals (e.g., mergers, closures, product-line changes) to determine when revalidation is required. Monitoring is paired with controlled review workflows so affected records can be evaluated, updated, and released with traceability.
