Someone on your left speaks French and someone on your right speaks English; both individuals need to speak to each other. The systems analyst is the middleman, assessing the needs of the end-user and translating them into programming or turning over the programming responsibility to the development department. What are the business requirements? Who will comprise the user community? How large is the application going to be? Will it be internal or external? These are all questions facing the systems analyst, who spends much of the day in front of the computer poring over these issues.    With a new product, other elements come into play, such as network location, user community, type of machine, and portability. If the analyst is reviewing an established product, the user community will dictate its changes and enhancements. "One of the biggest surprises in my 25 years of technology work is that people who have a creative background as opposed to a degree in computer science tend to make better systems analysts," says one seasoned professional. "The best analysts I've come across came from backgrounds in theater, art, and filmmaking. But they were all able to see and grasp big-picture concepts very quickly, and break them down into subcomponents. People who have a computer science or math background tend to be very technical, and sometimes that can be a hindrance." Systems analysts need to be independent thinkers – people who can "think out of the box" by grasping concepts quickly and seeing the big picture as opposed to the small details. "I also look for someone who is self-motivated. Here take the ball and run with it and come back if you have any issues," says one employer who heads up a technology group.

Sabe-se que um deles usava óculos, outro era tagarela, outro era excessivamente magro, outro detestava Davi, outro tinha 25 anos e o último era solteiro, características estas próprias de apenas um deles.

− a pessoa de 25 anos sentou-se entre Carlos e o homem que sentou-se à frente daquele que detestava Davi;
− Fernando, que tinha um ótimo relacionamento com todos, sentou-se ao lado do homem excessivamente magro e defronte ao solteiro.

Nessas condições, é correto afirmar que o homem de 25 anos era
