nummerspecifikation

Nummerspecifikation is a formal documentation of how numbers are assigned and structured to identify items, parts, documents, or events within an organization. It defines the overall purpose of the numbering system, the scope of items covered, and the goals for traceability, uniqueness, and interoperability between systems.

The specification describes the format and syntax of numbers, including the length of each field, permissible characters, prefixes or suffixes, and the use of check digits or checksum algorithms. It also sets rules for allocation, ownership, and lifecycle management, such as when numbers are issued, retired, or recycled, and how revisions are handled.

Geographic and domain contexts may influence the scheme: in manufacturing it may reflect product families and manufacturing lots; in IT asset management it may capture asset class, location, and serials; in documentation it may encode versioning and revision history. The nummer spec is usually implemented in configuration management, ERP, MDM, or document control systems, and is maintained in a central governance process with versioning and change control.

Good practices include avoiding duplication, designing for stability, separating human-readable and machine-readable elements, and providing migration guidance when the scheme changes. An example pattern could be PROD-23-000123-R2, where PROD denotes the product family, 23 the year, 000123 a sequence number, and R2 the revision. This illustrates how a well-defined nummerspecifikation supports both clarity and automated processing.
