But that’s not the only way the technology giant, which employs roughly 350,000 workers, knows who in the workforce is currently searching for a new position. IBM artificial intelligence technology is now 95 percent accurate in predicting workers who are planning to leave their jobs, said Rometty.

During Rometty’s seven-year tenure as CEO, IBM has been improving its AI work devoted to the retention of its employees.

Rometty would only say that its success comes through analyzing many data points. Read more:
