RALEIGH, N.C. (AP) — North Carolina state government does a poor job estimating what the actual costs of an information technology project will be and how long it’ll take to complete the job, State Auditor Beth Wood’s office said Monday.

The performance audit, the latest in a series of reports from Wood’s office highlighting shortcomings in how state government builds or manages computer systems, reviewed 84 projects. Their actual costs were $356 million higher, or more than twice as much than the state agencies originally estimated, auditors wrote. The projects also took 389 days longer than initially estimated, or 65 percent longer, according to the analysis.
