One of the most significant advances is the ease with which assessment criteria can be defined for each position within the organisation, whatever the skills or qualifications involved and whatever the level of remuneration. Vitae is designed so that the organisation itself defines its own benchmarks, using the system's database expansion facilities. Vitae also helps managers to develop a more thorough approach to the selection process and to motivational issues affecting existing personnel. Where individuals are appraised at intervals over time, managers are able to track patterns of change and an individual's progress. In identifying stress and other factors, Vitae personality profiling helps to reveal problems that may be at the root of decline or improvement in performance.
