Abstract: A method includes acquiring (601) process data collected in an industrial process control and automation system (100). The method also includes reducing (603) a dimension space of the process data by combining two or more parameters (405, 410, 415) of the process data or examining a frequency response of the process 5 data. The method further includes determining (605) a change in a process based on a change in the process data in the reduced dimension space. The method also includes outputting (607) a result based on the determined change in the process.
