SCCM Hardware Inventory Without Noise

Choose decisions first

Define the operational question before enabling a class: which devices need a BIOS update, which models are nearing retirement, or where is disk capacity blocking an upgrade? If no workflow consumes a class, it should not be collected on every cycle.

Extend deliberately

Use a custom WMI class or registry-backed value for local signals that are not available by default. Name properties consistently, document units, and set a review date. Avoid collecting volatile values that change constantly and create unnecessary database churn.

Keep collections readable

Separate raw inventory reports from action collections. A report can tolerate more detail; a deployment collection needs a narrow, explainable rule and a refresh cadence that matches the change being managed.

Operational checklist

• Map each inventory class to a decision.
• Document custom properties and units.
• Review collection refresh intervals.
• Retire unused extensions quarterly.
