One of the key causes of employee turnover is the lack of occupational interest. As a result of 60 years of research and meta-analyses, a high correlation has been identified between professional interest and performance in the workplace. Great People Inside developed a set of statements with a (Cronbach Alpha Score) validity of at least 0.85 on each of the 6 dimensions (realistic, investigative, artistic, social, conventional and enterprising). Thus, GR8 Interest supplements the numerous questionnaires for the identification of occupational interest, while having the great advantage of giving you the ability to identify the level and combination of performance predicting interests for each job. The algorithms developed by Great People Inside ensure extra validity and, first and foremost, offer specific predictability, by using performance models which are based on concurrent studies or labour analysis. These automated methods can turn any user of Great People Inside systems into a fan.
