I work for company whose HQ is in the US, but has offices all over the world. Our computer system uses the "American" date format of mm/dd/yyyy, but at the same time we are required use dd/mm/yyyy in any texts. As this has lead to many costly misunderstandings, most of the offices outside of the US have started to use the DDMMMYYYY (17DEC2015) format to avoid misunderstanding, but only in unofficial documents and emails. In fact, many people from the offices in the US have followed, but the company still refuses to change the format in the computer system (because of the expense?), so our whole workforce has to recognize and mentally convert dd/mm/yyyy to mm/dd/yyyy and back, scores of times per day.

Homework: Why would switching the computer system to dd/mm/year be too expensive to imply?
