Of all the entries on this list, this one is without a doubt the most ironic of them all. We all know how important education is, as it helps to cultivate and develop a child’s mind, while also providing individuals with credentials and a pathway towards the profession of their choice, and it is up to the people who run the educational system to provide schools and students with the things that they need. The New York City Department of Education manages all of the public schools in the city, which is the largest school system in the U.S. This department gets an annual budget of around 25 million dollars, as it has to provide services for over one million students, services like transportation. In 2006, a New York City comptroller made a very costly typo when he added an extra letter to a word, which caused the computer’s accounting software to misinterpret a document regarding the Department of Education’s transportation budget. This mistake caused the department to spend double on their transportation budget, which ended up costing an additional 1.4 million dollars.
