Preparing Inventory in Mechanical Engineering: 3 Steps to Reduce Effort

In mechanical engineering, inventory rarely escalates due to a lack of counting teams. Usually, it's a matter of structure: project materials are scattered, articles have multiple variants and revision levels, spare parts warehouses operate continuously, and value-critical components are tied to the same processes as simple nuts and bolts. Those who prepare thoroughly here save time both during and after the inventory.

Sample inventory is a practical approach for this. HGB § 241 allows for recognized mathematical-statistical methods, provided the evidence value is equivalent to a full physical count. The key is ensuring that preparation and documentation are flawless.

1) Stabilize the Database, Define the Population Clearly

Before discussing rules, value limits, or samples, the database must be accurate. Otherwise, recounts and correction loops will occur. Key checks in advance:

• Separate storage areas if inventory management reliability varies (e.g., high-bay warehouse vs. assembly staging vs. external warehouse).
• Clean up discrepancies: Negative stocks, duplicates, items without target quantities, or discontinued articles.
• Analyze the structure: Identify where value is concentrated, where movement is high, and where outliers exist.

2) Full Count for Value-Critical Items and Special Cases

Samples become unreliable when too many "special cases" end up in the selection. In mechanical engineering, typical borderline cases should be excluded from sampling and undergo a full count:

• Positions without target quantities or with implausible data.
• High-priced components (e.g., drives, control units, spindles).
• Project-critical materials.
• Items that are small, expensive, or prone to confusion/shrinkage.

In practice: Expensive and complex items are counted fully; the remaining bulk is statistically verified. This reduces both risk and auditors' queries.

3) Finalize Workflow and Documentation in Advance

With sample inventory, it’s not just the result that counts, but the traceability. If rules and parameters are not properly documented, the work will come back to haunt you later. Before the inventory begins, the following should be defined:

• Warehouse workflow: Recording, control, and handling of deviations.
• Media-break-free data transfer: Using scanners, mobile devices, or regulated imports.
• Audit logic: Stratification, exclusions, parameters, and final reports.

Summary: Optimal Inventory Preparation

Three points save the most time in mechanical engineering:

1. Clean up stocks and clearly define storage areas.
2. Perform a full count for value-critical and unclear positions.
3. Document the process and evidence so they hold up during an audit.

This significantly reduces counting effort, blocking times, and rework.
