How do I estimate the effort to clean up our item master before an ERP migration?

Use the Item Master Cleanup Effort calculator. Enter your active item count, the share of records with missing or wrong attributes from a data profiling pass, and an average minutes-per-item correction rate. It returns steward hours so you can compare against Data Stewardship Capacity and set a realistic cutover date. Pair it with Data Migration Effort and the ERP Data Readiness Score to build a full pre-go-live plan.

What does a routing accuracy score actually measure?

The Routing Accuracy Score reflects how well your routings match reality: correct operations, work centers, run and setup times, and sequence. Inaccurate routings distort capacity loads, standard costs, and scheduling. Score a sample of routings against shop-floor observation, then use BOM Routing Mismatch and Work Center Data Completeness to find where the errors cluster so you fix the highest-impact records first rather than reviewing everything.

How much do duplicate items really cost us?

Duplicate Item Cost captures the recurring waste from redundant part numbers: split demand that defeats MRP netting, duplicate safety stock, extra purchasing effort, and inventory carrying on both records. Enter duplicate pairs, average carrying and handling cost, and expected demand splitting. Combining it with Data Error Cost usually shows duplicates are one of the easiest master data problems to justify fixing, since the savings repeat every planning cycle.

How many data stewards do we need to sustain governance?

Run the Master Data Governance Workload calculator to total the recurring create, change, review, and approval transactions per period, then compare against Data Stewardship Capacity, which converts available steward hours into throughput. The gap tells you whether to add headcount, tighten approval workflows, or automate validation. Master Data Approval Cycle Time helps confirm whether backlog is a staffing problem or a workflow bottleneck.

How do I build an ROI case for a data governance program?

Data Governance ROI weighs recurring benefits, mostly avoided Data Error Cost, fewer duplicates, faster approvals, and less rework, against program cost for tooling and steward time. Quantify the current pain first with Data Error Cost, Duplicate Item Cost, and Data Quality Defect Rate so the savings are grounded in your own records rather than industry averages. That evidence is what typically wins funding from finance sponsors.

Why is unit of measure conversion such a risk in ERP data?

A wrong UOM or conversion factor silently corrupts inventory balances, purchasing quantities, and costing, and the error can be off by orders of magnitude. The Unit of Measure Conversion Risk calculator scores exposure by volume of affected items, transaction frequency, and downstream impact so you can prioritize UOM validation. It pairs well with the Data Quality Defect Rate to track whether conversion errors are trending down after cleanup.

Best calculators in this category

Item Master Cleanup Effort: Estimate item master cleanup effort for manufacturing master data and data governance using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.
Routing Accuracy Score: Estimate routing accuracy for manufacturing master data and data governance using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.
Work Center Data Completeness: Estimate the cost of bringing work center master data to a complete, governed state across a plant or ERP instance.
ERP Data Quality Score: Estimate ERP data quality for manufacturing master data and data governance using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.
Duplicate Item Cost: Estimate the cost of finding and resolving duplicate item master records, including merge effort and matching tooling.
Unit of Measure Conversion Risk: Estimate unit of measure conversion risk for manufacturing master data and data governance using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.
Master Data Governance Workload: Estimate master data governance workload for manufacturing master data and data governance using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.
Data Stewardship Capacity: Estimate data stewardship capacity for manufacturing master data and data governance using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.
BOM Routing Mismatch: Estimate the cost of reconciling BOM-to-routing mismatches that drive bad costing, shortages and scheduling errors.
Item Classification Workload: Estimate item classification workload for manufacturing master data and data governance using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.
Obsolete Item Cleanup: Estimate the cost of retiring obsolete item master records, including verification effort and archiving setup.
Supplier Master Cleanup: Estimates the cost of cleansing, deduplicating, and re-validating a manufacturing supplier master file.
