美国苹果公司联合创办人乔布斯曾说:“消费者并不知道自己需要什么,直到我们拿出好的产品,他们会发现,这就是我要的东西。”在i Phone出现前,大众并没有智能手机的概念,进行调查自然会没有结论或得到偏差的结论。在社会服务中,社工也常有类似的误区——以为发现和了解需求只要通过进行调查就可以了。 Jobs, co-founder of Apple Computer, once said: “Consumers do not know what they need until we come up with good products and they find out that this is what I want.” Before i Phone appeared, Without the concept of a smart phone, the conclusion of the investigation will naturally be no conclusion or bias.
