For a software engineering organization to be efficient, it is key that everyone is an efficient communicator. Everybody needs to be calibrated in what to communicate, to whom and how to ensure information spreads properly in the organization. Having smart people with a lot of knowledge results in progress only if information flows well in the veins of the organization. This does not mean that everyone needs to communicate everything – on the contrary, it is also the responsibility of every individual to make sure there is the right amount of communication, not too much and not too little.
Key in anything. Faulty language is faulty everything from there on out.
