This is a minimum-style description of what activities a person typically engages in in their designated role as described on this wiki (eg. application expert or systems expert). This should be kept as short as possible; just a few words, not even a full sentence, but with leading capital letter and ending full stop character. This should not be regarded as a daily blog of what the person is up to, but should rather list more general things, or larger projects. This can be set multiple times to specify multiple different activities, and if so, they should be listed in decreasing order of importance.
In some cases, the phrase "Application expert in FIELD" is sufficiently descriptive in itself, and if so this property should be left blank.
