Team building.
Too often managers build a perfect job description and hope for the perfect fit candidate. Like the candidate was pressed in a factory.
Not often enough does a leader hire the person with the right set of skills and experience. A leader who hires someone like that can customize the job to fit that person’s unique skill set.
Team building is about building what you don’t have enough of - complimenting your weaknesses with another’s strength.
That’s how great teams thrive.
