The Office of Thrift Supervision’s list of technology priorities is long and wide. But chief information officer Wayne Leiss knows the end result will change the way the Treasury Department’s bureau regulates the banking industry. OTS is updating how it serves internal and external customers by upgrading its back off systems and by implementing functions such as a national customer complaint Web site. And OTS is doing this with a large cadre of federal workers instead of contractors. Because Leiss says, his government staff knows what the users’ needs better than anyone else. Leiss’s job is more complicated than most for two reasons–he also is the chief financial officer, and maybe more challenging, OTS is a revolving fund, meaning it does not get money from Congress. This makes him pay closer attention to OTS’s revenue flow.
