4.3.5 Guide Chart-Profile Method (Hay methodThe Hay guide Chart-Profile Method is a job evaluation system that is basically a factor comparison system, although it is also very similar to the point method since it uses points. The Hay system is used by more than 5,000 employees worldwide, including many of the largest corporations. This method uses three compensable factors:1.Know-how2.Problem solving3.AccountabilityFor each of these compensable factors, the Hay method uses two-dimensional matrices showing the number of points assigned to that factor. The points are determined by comparing the job description with the appropriate rows and columns for each matrix.For the know-how factor, there are four levels of managerial know-how(limited, related, diverse, and comprehensive)and eight levels of technical know -how (ranging from primary to professional mastery). Each level of technical know-how has three degrees, and within each cell there are also subcategories that recognize three different levels of human relations skills(basic, important, and critical). An evaluator may select among at least 288(4x8 x 3x3) different combinations of managerial, technical, and human relations know-how to evaluate a job.
