- Cost above baseline for 28% to 86% of projects, depending on the source — not one number
Protocol 1.0; shares use a Wilson 95% CI. Heterogeneous across sources (chi² 114, df 5); pooled figure withheld.
- Cost more than 10% above baseline for 19% to 78% of projects, depending on the source — not one number
Protocol 1.0; shares use a Wilson 95% CI. Heterogeneous across sources (chi² 46, df 5); pooled figure withheld.
- Among projects that moved above baseline, cost growth of 12% to 109%, depending on the source — not one number
Protocol 1.0; medians use a bootstrap 95% CI (2000 resamples, seed 0). Heterogeneous across sources (chi² 110, df 5); pooled figure withheld.
- Finishing later than planned for 39% to 89% of projects, depending on the source — not one number
Protocol 1.0; shares use a Wilson 95% CI. Heterogeneous across sources (chi² 276, df 5); pooled figure withheld.
- Among projects that slipped, 5 to 39 months of slip, depending on the source — not one number
Protocol 1.0; medians use a bootstrap 95% CI (2000 resamples, seed 0). Heterogeneous across sources (chi² 48, df 4); pooled figure withheld.
- 11% of 555 completed projects — one source (Victorian IT Project Dashboard), not a sector figure
Protocol 1.0; shares use a Wilson 95% CI. Fewer than two sources report this measure; no pooling comparison is possible.
