From the Indianapolis Business Journal:

Deloitte employees Kathi Schwerdtfeger and Bari Faudree walked lawmakers through the plan they compiled following interviews with state workers at the Revenue Department, State Budget Agency, Department of Local Government Finance, and the treasurer's and auditor's offices.
The state has become a national model, they said, for processing individual returns more quickly and efficiently, but may have been deficient in hiring staff with enough expertise to track a tax check through the entire processing system. There also may be problems with internal controls at the tax department caused in part by high turnover.
Internal controls and reviews, designed to catch errors immediately and avert problems like those which led to the two major errors, "appear to have been a lower priority" than the tax return processing, Deloitte wrote in its report. The management of the department's IT and tax collection areas "may not have been as rigorous in detecting errors within the financial accounting systems."
But Schwerdtfeger and Faudree were careful to note these are areas to investigate, and are not necessarily problems.
State budget director Adam Horst said he was happy that answers could come by the end of the year.

Horst added that some areas the group will review, including employee proficiency, are not necessarily specific problems at the revenue department but could be part of general problems found in any government agency.
