Really, it has been a good day. But to help me remember, lest I get led astray:
1. Alternative chosen to make happen a desired future, such as achievement of a goal or solution to a problem.
2. Art and science of planning and marshalling resources for their most efficient and effective use. The term is derived from the Greek word for generalship or leading an army.
Means by which a strategy is carried out; planned and ad hoc activities meant to deal with the demands of the moment, and to move from one milestone to other in pursuit of the overall goal(s). In an organisation, strategy is decided by the board of directors, and tactics by the department heads for implementation by the junior officers and employees.
