There have already been plenty of articles written on the importance of creativity in the workforce. Assuming you buy into the importance of attracting creative types to your team, you will have an understanding of what to look for in hiring creative people. And then you will face the challenge of keeping these people on your team. I see this as a challenge because I don't believe our typical individual performance metrics are well suited to measuring creative individuals.
Consider some of the common metrics used to assess individual employee performance: on-time task completion; task management; completion of specific goals; project management — all of these measures are heavily geared toward favoring individuals who have a natural ability to be well-organized, methodical and goal-oriented. Perhaps this describes your ideal employee.
