What do these project success and failure statistics mean?
Missing some intended benefits is not the same outcome as cancellation, a budget overrun or a late milestone. Keep the outcome label attached when quoting a project failure statistic.

How widespread is project complexity in the surveyed group?
These observations describe professionals’ reported experience of complexity, not independently audited changes across every project in the economy.

Do structured frameworks guarantee project success?
No. The reported comparison is observational. Teams selecting a framework may also differ in project difficulty, resources, experience and other unmeasured ways.

What do the PMO comparisons actually measure?
Recognizing complexity and managing it successfully are different outcomes. Neither should be relabeled as overall project success or a causal return from creating a PMO.

How should different project-outcome studies be compared?
First match the unit, outcome, time window and respondent population. A project missing some benefits, a respondent rating delivery poorly and a cancelled project are not interchangeable events.
The web summary and PDF use different historical comparison wording. We exclude that historical comparator and the success multiple instead of reconciling them through an unsupported calculation.
What should a reusable project-outcome scorecard record?
Record the original objective, agreed scope, planned and actual dates, planned and actual spend, benefits owner and the date benefits were assessed. Separate each result rather than collapsing everything into one pass/fail label.
This is Workspace369’s suggested reporting checklist, not a validated instrument from PMI and not evidence that a tool increases success.
How this report was built
Methodology and limitations
- The PDF appendix reports 2,023 project professionals and 511 senior leaders across 35 countries, with weighting toward PMI’s global database. Quantitative fieldwork dates and item-specific bases are not disclosed in the inspected report; those details remain unknown.
- We checked selected numerical passages against the PDF pages. Percentages retain their reported outcome labels; no findings from a separate CEO study are presented as results from this practitioner sample.
- Workspace369 adds a definition crosswalk and a practical scorecard checklist. No new survey, effect size or causal model is claimed.
What these numbers cannot tell you
- This professional sample is not a census of projects or a representative sample of all small businesses. Self-report and selection effects limit generalization.
- Outcome definitions differ across the report. We omit the historical failure comparator and promotional multiplier because the summary and full report are not consistent enough for a clean cross-study calculation.
- The findings do not establish that software, a PMO or a framework caused better outcomes.
Freshness and corrections
Maintained by the Workspace369 editorial team. Review on new PMI research releases and correct changed definitions before comparing studies. The edition date changes only when the evidence or content is substantively reviewed; it does not change the underlying observation period.
First edition: . Data extraction, source attribution and arithmetic checked for this edition. No independent peer review is claimed.
