The invention provides a tool and method for monitoring and evaluating any industrial or commercial process, activity or system or the personnel carrying out that process, activity or system against a set of Performance Drivers for the process, activity or system; and for assessing the efficiency, capability or sustainability of that process, activity or system as a result of the monitoring. By utilizing both a weighting between each of the different statements and questions used to derive performance and compliance data from persons polled for input and a numerical maturity value given to the mean responses from different groups of those persons polled, the analysis of the data against the associated Performance Drivers permits the generation of assessment reports that assess compliance against individual statements and indicate the potential cause of any failure of the process, activity or system to attain its targets.
