A method and system which tracks productivity including summarization of "tasks performed" for productivity analysis. The tracking capabilities of the system uses a positioning system and includes a complete reconstruction (graphically if desired by overlaying the positional movements on a 2 or 3 dimensional map of the location) of a series of movements over a period of time. The system gathers the exact time and position information of an employee over a period of each work day and the task being worked on at any given moment of time. This data can be analyzed to determine, for example, non-productive movements, and provide a better foundation of information for productivity payroll including the relative "difficulty" of a task.
