Communication lies at the heart of any business. You should never write as though you were having a conversation. It can be just like Administrative Communication in many ways. A little while ago I was involved in a project where we had to redevelop part of a web site.
This is not an uncommon problem in business. It would be similar to a communications textbook many times. As the saying goes; lose lips sink ships.
Today, the world is closer together than ever before and an economic crisis in any one country has far-reaching effects elsewhere around the world. You should be conversational (e.g. write using the kind of words you might use if you were having a conversation) but not as though you were having a conversation. So use few words but don’t assume that the other person knows what you are talking about. Is it true that not everyone can be trusted with information? Many people would agree, some would go so far as to say that humans cannot be trusted with information, but why? Well, information is power and if you power-up those who cannot control their integrity levels or choose not to, then in a way giving them the information makes you an accessory to their actions.
You will be able to see a miniature of whoever you are talking too, watch the body language and get a much better feel for the conversation. In fact I would even go so far as to say that without communication there can be no business. Oftentimes, it can be just like a business writing textbook. This did not mean believing they were stupid (something business people often wrongly assume about those who read their communications) but that they just knew nothing about what I was trying to get across.
