THE STANDARD PRODUCT LIFE MODEL
Use this to remind you of the fact that you and the products you sell have a natural life cycle.
Theodore Levitt first published his four-stage Product Life Cycle Model in the Harvard Business Review in 1965. If you replace ‘Introduction’ with ‘Infancy’ the model actually depicts the major life stages that every person goes through. It may have been this cycle that inspired the model.
