Obsession and Stock Ticker are both what?
Obsession (board game) Obsession is a board game released in 1977 for two players in which the player wins by moving their ten rings along numbered slots. They must get all ten rings into the "safety zone" before their opponent. Each player rolls a pair of dice, and can choose either to move their own rings up, or their opponent's rings down.
Bullwhip effect The bullwhip effect is a distribution channel phenomenon in which forecasts yield supply chain inefficiencies. It refers to increasing swings in inventory in response to shifts in customer demand as one moves further up the supply chain. The concept first appeared in Jay Forrester's "Industrial Dynamics" (1961) and thus it is also known as the Forrester effect. The bullwhip effect was named for the way the amplitude of a whip increases down its length. The further from the originating signal, the greater the distortion of the wave pattern. In a similar manner, forecast accuracy decreases as one moves upstream along the supply chain. For example, many consumer goods have fairly consistent consumption at retail but this signal becomes more chaotic and unpredictable as the focus moves away from consumer purchasing behavior.
