Organiser

An organiser (British English) or organizer (American English) is a person who plans, coordinates, and oversees events, activities, or campaigns. Organisers manage logistics such as scheduling, budgeting, communications, and stakeholder coordination to ensure successful execution.

The term also refers to tools, systems, or devices that help arrange and manage items or tasks. Physical organizers include desk organizers, filing systems, drawer dividers, and travel organizers. Digital organizers encompass calendar apps, task managers, contact managers, and note-taking software that keep information and schedules orderly.

Usage notes and varieties: in British English, organiser is standard for both people and devices, while in American English organizer is commonly used for these senses. The concept spans several domains, including event planning, project management, and personal productivity.

Common types include: physical organizers that structure space and materials, such as binders, folders, and drawer inserts; and digital organizers that help manage time and information, such as calendars, to-do lists, and information managers. In professional contexts, organisers or organizers coordinate teams, suppliers, venues, and communications to produce events or campaigns.
