A note has been added to explain that events are to treated as actual activities

This capability describes how activities are represented. The activity may be:

performed on a product by a person;

EXAMPLE The changing of a flat tyre by the car driver.
performed on a product by another product;

EXAMPLE The running of fault diagnostics on a car engine by automatic test equipment.
performed by product;

EXAMPLE The running of a car engine.

This capability does not describe the use of activities that are part of a formal change process, and that are related to a Directed_activity and a Work_order. See capability C065: representing_work_order (includes Directed_activity) and C064: representing_work_done (contains a special usage of Activity_actual).
