What is needed is a system and method for using behavioral insights to determine who might be an appropriate placement or replacement within an organization. Accordingly, the present disclosure provides a more effective way to replace positions and teams. In some embodiments, the system may create a target candidate and pull from a pool of candidates to determine best fit using behavioral insights. In some implementations, the system may suggest a candidate based on an employer's requests. For example, an employer may specify they are looking for a candidate just like the one retiring. Based on the retiree, the system may find a viable candidate and present the person to the employer weighing what matches and what does not.
