ABSTRACT
Also called task. Technical disciplines tend to use the term ‘activity’, while non-technical disciplines seem to prefer the term ‘task’. The term ‘activity’ is used in this book. The term ‘activity’ may refer to a physical activity, an administration or
a management activity, a material delivery activity, or anything that has a finite duration and uses resources (and consequently money); an identifiable piece of work. Exceptions to this include:
• A dummy activity which exists to maintain work method logic in a network, has zero duration and uses no resources. A dummy activity might be referred to as a logic restraint. Project start and project end activities may also be optionally introduced in order to give identifiable start and end points to a project.
