This white paper discusses the importance of part numbering schemes in manufacturing and their impact on cost efficiency. It outlines two primary types of part numbering systems: intelligent and non-intelligent. Intelligent numbering schemes provide meaningful references to part types and characteristics, enhancing search efficiency and identification. However, they require significant training and can create bottlenecks in part issuance. Conversely, non-intelligent schemes are simpler and quicker to implement, requiring less training and allowing multiple personnel to issue part numbers without specialized knowledge. The paper also addresses the advantages and disadvantages of both systems, emphasizing the need for careful consideration of company requirements and existing processes when selecting a part numbering approach. Key questions are presented to guide organizations in determining the most suitable numbering scheme for their needs, highlighting the risks associated with relying on tribal knowledge and the potential benefits of integrating intelligent systems for part management.
