Why are there 3 different event roles?

The roles are:

1. Event manager
2. Event administrator
3. Event organiser

Events are a big topic and cover a wide range of activities. Also, the club will typically involve several people to be involved in their events. Some examples:

• Monthly leagues
• Various tournaments, singles, doubles, junior, senior, tennis, squash, squash 57 etc
• Social events like club dinners, dances, golf outings, exhibition matches etc
• Coaching programmes
• Club nights and other group sports activities

And many more. An "event" covers all manner of activities the club may support. So it's a multi-disciplinary topic that involves many people.

Typically, a club would designate just one or two individuals to be an event manager. The manager is responsible for defining every event and they would normally delegate the responsibility to administrate each event to another individual - the event administrator.

The event administrator is responsible for a single event (or more if the event manager had designated more). They would take responsibility for the recurrence of the event from month to month (e..g. leagues, club nights etc) or year to year. The event administrator may delegate responsibility to organise any one such occurrence to another individual - the event organiser.

The event organiser is responsible for the organisation of all the details of one specific occurrence of an event - for example this years' club championship. In doing so they oversee the joiners, build the draws and are generally responsible for making that event a success. Some events, like a social, would not involve building draws - which is less work for the event organiser.

In summary the above three roles are a hierarchy where one delegates to the next. In practice there will be many events where the event manager delegates to themselves - i.e. performs all three roles. This is fine, but for clarity and "diversification" the roles are well defined and separable.
