Enhanced communication skills help me in almost every situation-dealing with customers on the phone, defending designs to a review board, or expressing opinions in a team meeting. Not quite as much the writing as the speaking. The STC Program was an excellent one. The more opportunities to give presentations the better. Heavier emphasis on verbal skills.
Writing is important too, but many more opportunities to use verbal skills.
E-mail and phone mail, people don't explain themselves well or in an organized way. Technical people in general don't communicate well verbally. I don't deal directly with job openings.
