A poor IT-HR relationship can lead to bad IT hires. IT managers need to provide HR with sharp questions about applicants' technical skills. And HR pros need to do their homework about IT.
Ask your HR director to hire five new IT analysts skilled in hypervisor and server virtualization infrastructure and you'll likely get a quizzical look back. The fact is that technology in the workplace is advancing too fast for HR professionals (and really any non-IT personnel) to keep up with.
This widening knowledge gap between IT professionals and the HR managers who are tasked with filling positions causes real problems in hiring the right workers. The problem occurs most frequently when IT managers need to find an employee that has a very specific set of IT skills.
