Effectively managing your product development and manufacturing processes hinges on comprehending your personnel, components, and procedures. Maintaining meticulous oversight of individual components and assemblies is crucial for successful product development and manufacturing and significantly influences product outcomes.
Implementing a part numbering system facilitates the precise tracking and identification of each component and assembly in your inventory through assigning a distinct, unalterable identifier. This system aids in efficiently organizing new components, monitoring existing ones, and effectively managing procurement requirements. This article explores the advantages of a well-designed part numbering system and offers actionable guidelines for its implementation within your organization.
What Are Part Numbering Systems?
Part numbering systems are used by hardware organizations to track, organize, and label all parts and assemblies throughout the product lifecycle. These systems streamline operations by reducing part duplication and ensuring efficient categorization, thereby minimizing miscommunication between teams.
Maintaining simplicity in your part numbering is crucial. Overly rigid, complex, or ambiguous numbering schemes can impede implementation, potentially slowing down processes and leading to production errors. Integrating your part numbering system with Product Lifecycle Management (PLM) software is essential. This integration helps prevent conflicts with external part numbers and facilitates seamless navigation through various Bills of Materials (BOMs).
When part numbering relies on Computer-Aided Design (CAD) software or Enterprise Resource Planning (ERP) systems, managing data across these disparate platforms can be challenging. In contrast, a PLM system consolidates data from all sources, offering a comprehensive view of your entire product content landscape.
Dangers of Employing Divergent Part Numbering Schemes
Using multiple part-numbering schemes carries significant risks. The primary concern is the potential for miscommunication among suppliers, internal departments, and even customers. When different parties use varying identifiers to refer to the same part, it can easily result in production delays or errors.
Instead, the goal should be to establish a singular identifier for each unique set of part parameters that is universally recognized across all systems and stakeholders. This identifier can encompass multiple unique elements such as manufacturer part numbers (MPNs) or supplier part numbers (PNs). While these additional identifiers can help minimize duplication and provide different perspectives on uniqueness, the fundamental identifier should be the individual part number generated within your PLM platform.

Benefits of a Well-Designed Part Numbering System
A well-designed part numbering system can bring substantial advantages to your organization. Below, we’ll explore several key reasons why establishing a robust part numbering system is a worthwhile endeavor.
Mitigates Duplication Within Your Part Inventory
Duplicates in your PLM part inventory can lead to confusion and procurement challenges. By implementing a part numbering system, each item is assigned a unique identifier that, when properly implemented, eliminates duplicate entries in your PLM part library.
Serves as a Universal Identifier Across Different Software Platforms
Businesses often operate multiple software systems across various functions, which can lead to operational complexities. Having a standardized part number allows for consistency across platforms—from ERP systems to financial software—ensuring that each part maintains its integrity and traceability throughout different stages of operations.
Reduces Errors in Data Entry
Manual data entry poses risks of introducing errors or inconsistencies into software systems. Such errors can significantly impact business operations, causing production mistakes. With an automated part numbering system, you can minimize these risks by ensuring accurate entry of part numbers and linking all associated metadata correctly to their unique identifiers.
Streamlines Procurement by Ensuring Accuracy in Part Orders
Ordering incorrect parts can result in wasted time and money. Having unique part numbers enables precise ordering, ensuring that you procure the right parts in the right quantities, thereby minimizing procurement errors and optimizing inventory management.
By implementing an effective part numbering system, your organization can enhance efficiency, reduce errors, and improve overall operational effectiveness across various functions.
Six Practices for Designing Part Numbering Systems Effectively:
Having understood the critical role of part numbering systems in your PLM system, let's explore essential guidelines for creating an effective part numbering system.
Additionally, it's crucial to recognize that various suppliers employ different part number schemes, necessitating suitable tools for seamless system integration.
1. Implementing a Semi-Intelligent Customer Part Number (CPN) Scheme
Choosing the appropriate scheme for your part numbering system is an essential first step. While traditional emphasis was on intelligent part numbering schemes, it's now recognized that a "non-intelligent" system can be equally effective in many cases.
A semi-intelligent part numbering scheme strikes a balance that works well for most organizations, blending aspects of both non-intelligent and intelligent approaches. Typically, a semi-intelligent part number includes a prefix that indicates the category and a suffix that serves as a sequential identifier. This approach allows you to benefit from a structured parts numbering system without unnecessary complexity.
2. Opt for Numeric Part Identifiers
When selecting identifiers for your parts, prioritize numeric (number-based) identifiers over alphabetic (letter-based) ones. Alphabetic characters can be difficult to distinguish in certain fonts and may be mistaken for numbers, such as the letter 'O' and the number '0'. Numeric identifiers are easier to discern, minimizing data errors and simplifying use and communication among your teams, suppliers, and vendors.
3. Maintain Consistent Part Number Lengths
It's important to ensure that your part numbers maintain a uniform length. Typically, a length of six to eight digits is recommended. Consistency in part number length across all categories and systems helps minimize errors and promotes uniformity. However, it's crucial to strike a balance so that the numbers are not too short, thereby exceeding the allocated quantity of part numbers.
4. Ensure Item Identifiers are both Unique and Permanent
Ensure item identifiers are both unique and permanent
Every item identifier must be unique, ensuring no duplicates exist across any systems. Additionally, it's crucial that each part number remains permanent throughout the product lifecycle to avoid communication and data entry errors caused by constant changes or updates.
5. Avoid Special Characters and Leading Zeros
When establishing a part numbering system, it's important to steer clear of leading zeros, which are zeros at the beginning of a part number. Certain software tools may remove leading zeros from numeric values, potentially altering the intended part number. Additionally, ensure that any breaks within the number are denoted by dashes or hyphens, rather than spaces or letters.
6. Implement Category-Based Part Numbering
Incorporating part categories into your part numbering scheme facilitates efficient part retrieval and filtering within your component library. Typically, the category segment of the part number is encapsulated within a three- to four-digit prefix, as previously mentioned.
Summary
Effective management of product development and manufacturing relies on clear oversight and efficient processes, facilitated by a streamlined part numbering system with unique identifiers. These systems organize components, track assemblies, and enhance procurement efficiency.
Simplifying part numbering ensures integration with PLM software and reduces errors, promoting effective communication and collaboration across teams. A unified identifier system mitigates risks, improves inventory management, and optimizes operations throughout the product lifecycle.
