While I do agree with the importance of interpersonal skills, I think the 70% ratio is too great (especially if applied to all job fields). For example, a BME scientist who’s primary task is to create and run experiments in a lab setting will require more technical skill. While he/she may need to relay the results to a peer or committee, it will not suffice to be better at communicating the results than actually coming up with successful ones. For a BME consultant, however, the interpersonal skills will be weighed more as they work and communicate with a bigger pool of clients on a daily basis.
