How We Build This Report

Primary Source Collection

Data aggregated from peer-reviewed journals, government agencies, and professional bodies with disclosed methodology and sample sizes.

Editorial Curation

Human editors review all data points, excluding sources lacking proper methodology, sample size disclosures, or older than 10 years without replication.

AI-Powered Verification

Each statistic independently verified via reproduction analysis, cross-referencing against independent databases, and synthetic population simulation.

Human Cross-Check

Final human editorial review of all AI-verified statistics. Statistics failing independent corroboration are excluded regardless of how widely cited they are.

Statistics that could not be independently verified are excluded regardless of how widely cited they are elsewhere.

Technical and Integration Issues Interpretation

This staggering collection of statistics suggests that, while the ambition of an ERP implementation is to create a seamlessly integrated digital nervous system, the typical outcome more closely resembles a complex Rube Goldberg machine that's been built by committee, during an earthquake, and is now on fire.

Timeline and Schedule Delays Interpretation

It seems the only thing on schedule in an ERP implementation is the arrival of utter chaos, with the average project timeline serving as a tragically optimistic fiction that the actual work immediately and enthusiastically contradicts.
