If someone were looking into implementing a selection system I would suggest that if they can answer a few questions in that process, then they will be better off in the long run. The question is what do they want to accomplish by that? Is it simply a turnover challenge, or a productivity challenge, do they have a need to hire people faster because of a competitive labour market?
Next, they need to decide where the pain is. Have they quantified that pain? In other words, have they put a dollar amount on what turnover rate costs their organization? If they put a dollar amount down and do a financial analysis, then the final thing they should look at is the return on investment. - Jeff Furst of FurstPerson
