Various embodiments of the present invention provide improved computer systems for the evaluation of the performance of employees. Embodiments may use an engagement algorithm to calculate a single engagement score for each employee. Embodiments may use a second algorithm for skills to calculate a single skills score for each employee. A third algorithm may plot the employee's engagement score against the employee's skills score on a two-dimensional graph and indicate what scores are needed for a good evaluation and what scores are needed for a great evaluation. Various embodiments of the invention prescribe specific aspects of a job to coach to improve the employee's performance. Embodiments of the system archive and maintain all evaluations and scores for employees and provide access to them to subsequent supervisors.
