Before moving into training and coaching, I was an IT Consulting Engineer for 25-plus years. To this day, I have a left-brain bent. But I remember the experience that changed my perspective on what makes a powerful technical communicator (hint: it involves both hemispheres).
I was watching a very senior engineer at Cisco give a technical presentation. This engineer was so senior and well-regarded, he held a prestigious Fellow position at the high-tech company.
