How Mine Site Equipment Data Quality Scoring Works
A plain-English explanation of the scoring methodology Struktive uses for mine-site equipment registers — including the mining score floor and why it exists.
A quality score of 85 on a mine-site equipment record means something specific: the record has a confirmed OEM name, a valid serial number, a parseable mine hierarchy location, and a classified equipment category. Here is exactly how that score is calculated — and why mining records are scored differently from data centre assets.
Key Takeaways
- Mine-site equipment records are scored across seven dimensions: serial number, manufacturer, location, model, category, uniqueness, and status.
- Mining sector weights differ from DC weights — serial number and manufacturer are weighted higher because they are the primary compliance anchors for mine-site EAM.
- The mining score floor caps any record at 30 if it is missing all three of: serial/asset tag, cost centre, and location.
- A score of 70+ indicates the record is ready for EAM import with minor manual review.
- A score below 40 indicates the record needs significant remediation before it will import cleanly.
The Seven Scoring Dimensions
Every mine-site equipment record processed by Struktive receives a quality score between 0 and 100. The score is calculated across seven dimensions, each weighted according to its importance for mine-site EAM compliance.
| Dimension | Mining Weight | DC Weight | Why It Differs |
|---|---|---|---|
| Serial number | 20 | 15 | Primary compliance anchor for warranty and OEM service contracts |
| Manufacturer | 18 | 15 | Required for spare parts linkage and OEM-specific maintenance procedures |
| Location | 18 | 20 | Mine hierarchy location is important but correctable post-import |
| Category | 15 | 20 | Equipment classification is important but less critical than identity fields |
| Model | 14 | 15 | Model number enables specifications lookup |
| Uniqueness | 10 | 10 | Duplicate detection — same weight across sectors |
| Status | 5 | 5 | Status is easily corrected post-import |
How Each Dimension Is Scored
Serial number (20 points): Full 20 points if a valid serial number is present and passes format validation. 10 points if an asset tag or fleet number is present but no serial. 0 points if neither is present.
Manufacturer (18 points): Full 18 points if the OEM name was resolved to a canonical form from the vendor alias map (e.g. "CAT" → "Caterpillar"). 9 points if the name was passed through unchanged (unresolved). 0 points if no manufacturer is present.
Location (18 points): Scored based on how many levels of the mine hierarchy were successfully parsed. Full 18 points for 4+ levels (site/area/level/zone). 12 points for 3 levels. 6 points for 2 levels. 0 points for 1 level or unparseable.
Category (15 points): Full 15 points if the record was classified into one of the 12 mining equipment categories. 0 points if the record could not be classified (returns "Unknown").
Model (14 points): Full 14 points if a model number is present and was expanded (e.g. "793F" → "793F Mining Truck"). 7 points if a model is present but not expanded. 0 points if no model is present.
Uniqueness (10 points): Full 10 points if no duplicate is detected. 5 points if a potential duplicate is flagged. 0 points if a confirmed duplicate is detected.
Status (5 points): Full 5 points if the status was resolved to a canonical EAM status. 0 points if the status is missing or unresolvable.

The Mining Score Floor
Any mining-sector record that is missing all three of the following fields is capped at a maximum score of 30, regardless of other field quality:
- Serial number or asset tag
- Cost centre
- Location (any parseable level)
This floor exists because these three fields are the minimum for mine-site compliance. A record without a serial number, cost centre, and location cannot be meaningfully linked to a maintenance history, a cost centre budget, or a physical location in the mine. Allowing such a record to score above 30 would create a false impression of import readiness.
Interpreting Scores
| Score Range | Interpretation |
|---|---|
| 85–100 | Import-ready. Minor manual review recommended. |
| 70–84 | Import-ready with targeted fixes. Review flagged issues. |
| 50–69 | Requires remediation. Multiple fields need attention. |
| 30–49 | Significant remediation required. Consider whether the record is worth importing. |
| 0–29 | Not import-ready. Missing critical fields. |
Records capped at 30 by the score floor are displayed with a distinct badge in the Struktive results view — so reviewers immediately know the score is floor-capped rather than organically low.
