Christina Koslosky, Orange County’s chief information officer since March 2014, resigned last Friday, according to multiple county officials.
Top-level officials are saying little publicly about the reasons behind her departure.
“She is a class act and I will miss working with her,” county CEO Frank Kim said in an email to department heads Monday.
Koslosky, who did not return a call through the county for comment, is the second county IT director in just over two years to leave. Her predecessor, Mahesh Patel, abruptly retired in February 2014 amid criticism regarding cost overruns and other issues within the department.
Koslosky’s resignation comes the same month as the deadline for the county’s largest IT contractor, the European company Atos, to get back on track on a massive $132-million project to upgrade county phones and computer networks.
The work is months behind schedule, which has forced the county to pay millions of dollars extra to keep older contracts running, Koslosky has told the county Board of Supervisors.
Atos, which took on the contract when it bought Xerox’s IT services division last year, was given a year-long list of delivery dates last June to meet or else face the termination of their contract.
Sources close to the county say several department heads have been distrustful of Koslosky and the central IT department and have opposed efforts to centralize their systems.
That distrust was memorialized in a letter last year by four department heads saying they have “serious concerns” about the centralization and asking to be left out of it.
“We would like to exercise our right to opt out of the proposed IT Shared Services model,” said the memo from Assessor Claude Parrish, Auditor-Controller Eric Woolery, Clerk-Recorder Hugh Nguyen and Treasurer-Tax Collector Shari Freidenrich.
More recently, county agencies have been running into problems with computer and phone networks failing, sometimes for hours at a time, according to a county log of system disruptions related to Atos.
The county’s assistant IT director, Charles Eckstrom, has been named acting head of the department until a permanent replacement is found, Kim wrote in his Monday email.
Eckstrom joined the county last October after over a decade in senior IT positions in the private sector, including at Deloitte Consulting, Countrywide, UnitedHealth Group, and Toshiba Corporation.
