Attention to Detail and the important role it plays in the design process.
Attention to detail makes for a better experience in any industry. A mint sweet on your pillow at the hotel or a mint with your cheque at a restaurant makes for a more enjoyable travelling experience. Detectives and law officials know that it is in the details of a crime scene that they find success. Engineers and architects know that the stability of the most enormous structure depends on the integrity of its smallest element.
Why then, should it be any surprise that the integrity and success of your design depends heavily on the attention you give to the details therein? Paying close attention to detail simply makes your design more professional.
Even simple maths need attention, moreso if the are going to be on the cover of a document, that is going to be use for research and important knowledge gathering tasks. I had a brief moment of questioning my understanding of maths, when I saw the front cover of Census 2011 statiscal release say 21÷7=6.
The agency that did this for Statistics South Africa and the communication team at Statistics South Africa, need to be taught about the importance of attention to detail and maybe go for some elementary maths.
They might know South Africa, all it's statistics and understand that it's our home, but I doubt they pay attetion to detail and may be they don't understand simple Maths. 21÷7=3, not 21÷7=6
Such mistakes teach the wrong kind of maths, are bad for PR and should not happen. But I guess that's why it's called a mistake.
