Responses about the personal definition of the respective jobs of CRA (i.e. working on behalf of the sponsor), CRT (i.e. working on behalf of the centre with the investigating team), and CRPM. Each surveyed person had to define each particular task in terms of relationship with the job as either ‘major’, ‘minor’, or ‘beyond job scope’. An optional ‘do not know’ was also offered. For each job, the tasks are ranked by decreasing rate of ‘major’ responses, or rate of [‘major’ + ‘minor’] in case of equally ranked tasks. The response rate per item and per task is shown by a horizontal stacked bar (black for ‘major’, grey for ‘minor’, striped for ‘beyond job scope’, and transparent otherwise). The percentage values appearing over each bar are those which were considered for the ranking mentioned above. The abbreviations used to describe each task are explained in Table 1
