What was corrected
The article cited a single-year PMI Pulse of the Profession figure combining an '$97 million per $1 billion' statistic with an '11.4 percent' waste figure that actually come from two different report years, gave Bent Flyvbjerg's findings as 86%/88% over budget/schedule with a 73% IT overrun figure, attributed a Denver International Airport baggage-system analysis to a researcher named Caleb Racicot, cited Heathrow Terminal 5's cost as 4.2 billion pounds with specific but unverifiable figures for risk budget and contractor count, cited a $100 million dollar figure for the Toy Story 2 production rescue, and attributed the UK Government Digital Service's savings figures to the Prime Minister's Delivery Unit.
The section now presents the PMI waste figures as separate statistics from different report editions rather than one combined figure, gives Flyvbjerg's real published statistics (about half a percent of projects hitting all targets, a 62 percent median cost overrun, and the well-known 'one in six' black-swan statistic for IT project overruns), correctly identifies Ramiro Montealegre as a researcher who has written on the Denver International Airport case, gives Heathrow Terminal 5's real cost of 4.3 billion pounds while describing its risk-management practices in accurate general terms, describes the Toy Story 2 rescue without an unverifiable dollar figure, and describes GDS's cost savings without attributing them to the Prime Minister's Delivery Unit, which had already been abolished before GDS existed.
Why this is better
Web searches for each specific statistic and case-study detail either found the real figure differed from what was cited, found the figure came from a different year or source than stated, or found no evidence the specific detail exists. Since the underlying reports, researchers, and organizations are real and the general lessons drawn from them are sound, the section was rewritten rather than removed, correcting the specifics while preserving the legitimate substance of each case.
