As the speed of change in the marketing environment quickens, time horizons are becoming shorter. Nevertheless, most firms carry out strategic planning every 3– 5 years and treat the process as a means of checking whether the company is on track to achieve its vision and mission. Ideally, strategies are both dynamic and interactive, partially planned and partially unplanned.

Marketing is not confined to any particular type of economy, because goods must be exchanged and therefore marketed in all economies and societies except perhaps in the most primitive.
