The Harrison Assessment system uses 6500 job-specific formulas and 175 job performance traits to accurately predict employee performance. It evaluates eligibility, suitability, personality, work preferences, and other factors. The system is based on Enjoyment Performance Theory, which states that enjoyment of job tasks and fit with the work environment leads to better performance. It also uses Paradox Theory to provide deeper psychological insights and predict stress behavior. Using the Harrison Assessment can help businesses reduce costs, improve workforce planning, increase productivity and retention, and achieve better results.
