| McKinsey "aftermarket 25% vs 10% EBIT margin" |
Published 27 July 2017 — nine years old |
BCG Feb 2025: services ~2× the 15–25% equipment margin; top performers ~42% gross / ~20% EBIT |
| "Aftermarket margins up to ten times higher (Bain)" |
No Bain primary source reachable. Appears to originate in vendor blogs. "McKinsey: aftermarket margins 25–35% higher" is not in any McKinsey source |
The BCG 2025 figures above |
| Siemens "$2.3m/hour automotive downtime" and "$1.4trn / 11% of Fortune 500 revenue" |
Published 2024 but data covers Apr 2019 – Mar 2023, n=181; the $1.4trn is an extrapolation and losses are down 6% since 2022. No 2025/26 update exists |
Always date it, and pair with ABB's $125k/hour median, n=3,215 |
| "65% of manufacturers say workforce is their primary challenge" |
NAM Q1 2024. Current figure is 46.95%, ranked 6th (NAM Q2 2026) |
46.95% / 6th, noting raw material costs are now #1 at 83.1% |
| Deloitte/MI "1.9m unfilled manufacturing jobs by 2033" |
April 2024, fielded Dec 2023, base >200 firms. No 2025/26 refresh |
Cite as "a 2024 study projecting to 2033" and pair with live JOLTS |
| Plant Engineering "88% preventive / 51% run-to-failure / 52% CMMS" |
A 2020 study published June 2021 — six years old, widely mislabelled as 2025 |
Plant Engineering 2026 (67% name predictive maintenance most-critical) and ABB's 21% run-to-fail |
| "67% of manufacturers still rely on reactive maintenance" |
No primary study exists. Appears only in aggregator blogs |
Challenge #7's water-utility figure — governmental and unarguable |
| "23% of unplanned downtime caused by unavailable spare parts (Aberdeen)" |
Attributed to Aberdeen with no report title, number or year; not retrievable; Aberdeen's service research is 2010–2015 vintage |
Do not use. No substitute found. |
| OEE "~60% typical for discrete manufacturing" |
No locatable primary survey |
The 85% world-class figure IS defensible — TPM arithmetic (90% × 95% × 99%), not survey data |
| Warranty fraud / leakage "3–5% of warranty spend" |
No credible source found at all. Widely circulated in warranty-software marketing |
The SEC-audited reserve and catch-up-accrual figures in bet 04 — stronger anyway |
| "Cost of knowledge loss" (IDC "$31.5bn lost by Fortune 500") |
Traces to unretrievable 2000s-era white papers |
Siemens' 49→81 minute recovery degradation, and the 86%-vs-53% first-time-fix spread |
| "25% of utility workers retire within 5 years" (CEWD) |
Traces to 2012 framing, and CEWD later reported the opposite (9.7% eligible within 5 years, lowest since 2016) |
ASCE/EPA: ~one-third of the water workforce retirement-eligible over the decade, median age 48 |
| "Only 5.5% of companies are AI high performers" |
McKinsey's actual published wording is "about 6 percent" |
6% |
| BCI Supply Chain Resilience Report 2025 or 2026 |
Does not exist. Latest edition is 2024 |
Cite the 2024 data as 2024 — including that Excel is still the #1 tool for recording disruptions |
| PwC "$5.5trn tied up in working capital" |
2021/22 vintage; the global study page is a 404 and no 2025/26 edition exists |
Hackett's $1.94trn (2026) |
| Transformer / switchgear lead times ("128 weeks", "+77% since 2019") |
All vendor or SEO content |
IEA: "wait times for transformers and cables have doubled in the past three years"; or ASCE 2025's 80–210 weeks with its June 2024 date |
| Aggregate 2026 hyperscaler capex ($650bn / $690bn / $725bn / $760bn) |
Mutually inconsistent aggregator figures |
Only Meta's $130–145bn guidance was verified from a primary filing |
| "~10,000 entities in scope for California SB 261" |
CARB's own working list is 4,160 rows / 3,127 unique names |

Implausible against every peer estimate |
