I think krp67 brings up a very interesting and important topic in regards to communication techniques and style for medical device projects, and I think many projects struggle simply because of poor communication. I think the 2 major forms of communication that should be used for a project are face to face and email. In general I agree that face to face is the best, but in some situations I think email is also very appropriate. Email chains provide traceability so that it is easy to look back and remember decisions that were made previously and conversations that were had in the past. However, when discussing detailed topics email can be very confusing and in that case it is better to have face to face meetings and just take notes.
