Human resource specialists who know their stuff attempt to validate selection methods against the performance of the people selected so that the process can be modified and improved as time goes on. Some firms keep records of who interviews applicants. When recruits subsequently do especially well or poorly in their jobs the human resource people try to analyse what the interviewers saw or missed. As a result recruitment and selection can be made more effective. It is a good thing for team leaders to cooperate with this activity or press for it to occur if it does not already happen. Everything that can be done to improve the quality of the people who are taken on is very much in the firm’s and the team’s interests. It is a prime concern for team leaders.
