The study also found that world-class IT organizations spend 23% more on outsourcing than median companies, focusing on technology infrastructure rather than on "riskier" areas of outsourcing, such as application development.
Another finding is that world-class companies deliver 91% of all projects to spec, on time and on budget, while median companies meet these criteria 68% of the time.
Also, 100% of world-class companies have made their senior IT executive a member of the senior management committee, compared with 69% of median companies.
To receive Hackett's world-class designation, an organization must score in the top 25% of Hackett's database in both efficiency (cost and productivity) and effectiveness (quality and value) metrics.
