California state government doesn't have a great history of on-time, on-budget information technology projects.
Most recently, Covered California, the state's online insurance exchange, launched with problems that frustrated thousands of customers. Last year, a statewide court computer system was halted - - after more than $500 million was spent on it. And earlier this year, the State Controller cancelled a vendor contract on a new payroll system that has been under development for nine years.
Even so, the state is in the midst of multiple huge projects designed to replace aging infrastructure. Together, these major projects are anticipated to cost about $4.2 billion, according to the state's Department of Technology.
