Tufte's argument that the space shuttle Challenger disaster was a direct result of the poorly displayed information. This example of the possible consequences of poor data display is certainly extreme. But similarly, poor data displays are an everyday occurrence in many organizations in the world and lead to mistakes; missed opportunities; and the loss of time, money, and sometimes, life or limb. the development of new ways of visualizing information is an active and exciting area of current research. However, to properly and effectively apply these new methods, one must first develop an awareness of where and how information is currently being displayed badly. Find an example of a poor information display that is currently in use in a business organization.

Statement: If the manager increased the price and operated at maximum capacity, the cafe would be profitable.Truthfulness: False If the cafe operates at the break-even price for their maximum capacity, it means that their revenues would be just enough to cover their costs, resulting in a breakeven point. There would be no profit in this scenario. Increasing the price while operating at maximum capacity may generate higher revenues, but it does not guarantee profitability as it depends on the costs involved. Statement: If the cost of coffee increased during the week, but the price remained the same, the cafe would still break even.Truthfulness: False If the cost of coffee increased while the price remained the same, it would directly impact the variable costs per cup. This would lead to a decrease in the gross margin per cup, and therefore the cafe would not break even. The increased cost of coffee would reduce the profitability unless the price is adjusted to compensate for the higher…
