Recruiting, if done correctly, is an effort that needs to be coordinated with several other corporate functions. Let's see why. Managers and team leaders play a major role in the success of the business. When they go out recruiting, they do a variety of beneficial things besides just finding candidates. But most importantly, a manager's role also requires them to be on the leading edge of knowledge and business practice, and recruiting is an extraordinary learning tool.
Managers have a tendency to be inward focused.
In a fast changing world, a few months of isolation can lead to costly mistakes in product design and customer service. Isolated decision-makers can cause both the qualities of their product and the process decision making to go down as well as weaken the quality of their people decisions. Candidate lists need to become potential client lists and vice versa. Sales people need to become recruiters and recruiters need to also think like sales people. New product ideas might come up during the course of recruiting discussions as well.
