, Landmark Worldwide's core business operation is the delivery of seminars and training courses which aim to offer improvements in personal productivity, vitality, communication skills, and decision-making. Some of these are intensive two- or three-day courses. Landmark structures others as weekly three-hour seminars over a three-month period. The organization also advertises six- and twelve-month training programs in topics such as leadership, teamwork, and public speaking. Some of the courses require participants to start a community project, and those courses are structured to support them in the design and implementation of such projects.
