Introduction: Why Taxonomy Matters in Material Management
In today’s industrial landscape, organizations are drowning in data—especially when it comes to materials, parts, and spare components. From bolts and bearings to electrical panels and valves, the ability to organize and retrieve material data efficiently has become mission-critical.
The key to managing this growing complexity? A well-designed taxonomy.
In the context of material cataloguing, taxonomy refers to a hierarchical structure that systematically groups data based on defined categories and relationships. A robust taxonomy serves as the “digital shelf” on which every item in your inventory sits, making information easy to find, analyze, and maintain.
This article explores the concept of taxonomy in material cataloguing, how it differs from classification, and why it's foundational to modern inventory and asset management systems.
What Is a Taxonomy?
Taxonomy originates from the biological sciences, where it is used to classify living organisms. In data management, taxonomy refers to a structured framework for organizing terms, objects, or entities based on shared characteristics.
In material cataloguing, a taxonomy:
- Groups items by categories and subcategories (e.g., Electrical > Motors > AC Motors)
- Establishes parent-child relationships between concepts
- Enables faster, more accurate data navigation and retrieval
- Forms the backbone of data governance and master data management (MDM)

Taxonomy vs. Classification: What’s the Difference?
Though the terms are often used interchangeably, taxonomy and classification are not the same.
Aspect | Classification | Taxonomy |
Purpose | Categorizes items by code or standard | Organizes items in a navigable structure |
Focus | Coding, naming, standardizing | Grouping, structuring, navigating |
Structure | Often flat or code-based | Hierarchical (parent-child relationships) |
Output | Code (e.g., UNSPSC: 26121607) | Navigation Tree (e.g., Mechanical > Valves) |
Role in Cataloguing | Standardizes identity | Structures user experience and data access |
In short: classification tells you what an item is, while taxonomy shows you where it fits within a broader system.
Why Is Taxonomy Essential in Cataloguing?
A clean taxonomy does more than organize—it transforms how businesses interact with their material data. Here's why it matters:
1. Improves Searchability
Users can navigate through a structured path rather than searching blindly through inconsistent descriptions.
Example: Instead of searching for “motor,” users follow:
Electrical > Motors > Induction Motors > Three-phase
2. Prevents Duplication
Taxonomy exposes redundancy. When multiple departments label items differently, taxonomy helps consolidate variants under the same logical node.
3. Enables Better Reporting and Analysis
A consistent taxonomy allows spend data, inventory turnover, and usage trends to be analyzed by logical groups.
4. Supports Integration with ERP & EAM Systems
Systems like SAP, Maximo, or Oracle rely on clean data taxonomies for accurate asset tracking, requisitioning, and maintenance planning.
How to Build a Material Taxonomy
Building an effective taxonomy for cataloguing requires strategy, technical accuracy, and alignment with business goals. Here are the core steps:
1. Define the Top-Level Categories
These are your "segments"—broad groupings such as:
- Mechanical
- Electrical
- Instrumentation
- Tools
- Consumables
- Safety Equipment
2. Develop Subcategories and Attributes
Each segment is divided into smaller categories based on function or type. For example:
- Electrical > Cables > Power Cables > Armored Cables
- Mechanical > Bearings > Ball Bearings > Deep Groove
Each node can then include attributes like size, material, voltage, or thread type.
3. Use Industry Standards Where Possible
Reference systems such as:
- UNSPSC for general procurement
- eCl@ss for attribute-based classification
- ISO 8000 for data quality
These provide consistent naming conventions and help interoperability.
4. Validate with Subject Matter Experts
Involve engineers, maintenance personnel, and procurement teams to ensure the taxonomy reflects real-world usage and understanding.
5. Deploy in Master Data Platforms
The taxonomy must be embedded into your MRO or ERP environment and used consistently across functions—from cataloguing to purchasing.
Real-World Example: Taxonomy in Action
Imagine an oil & gas company that manages over 100,000 SKUs. Without taxonomy, similar items are scattered under names like:
- Motor 3Ph 400V
- 3 Phase Induction Motor
- Electric Motor (Industrial)
With taxonomy, these are all grouped logically:
Electrical > Motors > Induction Motors > Three-phase > 400V > 50Hz
As a result:
- Procurement can consolidate purchases
- Maintenance can identify alternatives quickly
- Inventory visibility improves across plants
Business Benefits of a Strong Taxonomy
Benefit | Impact |
Faster Item Retrieval | Reduces maintenance downtime and procurement cycle time |
Improved Inventory Accuracy | Helps eliminate duplicates and ghost inventory |
Enhanced Spend Visibility | Allows for more accurate reporting and supplier negotiations |
Reduced Operational Risk | Minimizes incorrect part usage and ensures compliance |
Easier Onboarding of New Staff | New employees navigate systems faster using intuitive structures |
A McKinsey study showed that companies with strong taxonomies saw up to 25% improvement in MRO data quality and 15–20% cost savings in procurement operations.

A Note on Adult Learning & Human-Centered Design
Taxonomy doesn’t just help systems—it helps people.
Most catalog users are busy professionals: mechanics, operators, or procurement staff. A good taxonomy respects their time and enhances their performance. By designing intuitive categories and logical paths, we:
- Reduce cognitive load
- Support faster learning curves
- Anchor item relationships through context
This is where taxonomy goes beyond data—it becomes a tool for empowerment.
Conclusion: Taxonomy as a Strategic Asset
A well-structured taxonomy is not just a technical implementation—it is a strategic foundation for operational excellence. It ensures that the right parts are used, at the right time, in the right place.
“If classification is the language, taxonomy is the grammar that gives it structure and meaning.”
For organizations serious about digital transformation, taxonomy must be part of their master data strategy. It improves not only inventory management but also collaboration, decision-making, and ultimately, profitability.
