Dr. Michelle O'Sullivan:

There are some good proposals internationally on what proportionality means. A number of guiding principles have been proposed and developed. One is that employers should not use technology to provide an answer that could not credibly be answered by technology. For example, it would not be credible for an organisation to use technology to do a 30-second recording of an individual and, based on those 30 seconds, an algorithm would decide whether he or she is suitable for a job. Principles are being proposed that could help with the issues around proportionality.
