THE INSTITUTEAre you dreading the possibility of having management duties added to your job responsibilities this year? Many engineers find themselves unprepared for the transition from focusing on technical tasks to overseeing other engineers. To help you gain insight into how to become an effective manager and leader, the IEEE Graduates of the Last Decade group recently sponsored a webinar titled “Geek in the Lead: Growing From Engineer to Manager.”

IEEE Senior Member B. Michael Aucoin, a professional trainer and consultant in electrical engineering, project management, and engineering management, presented the hour-long session in December, and it’s now available free for download. Aucoin is the founder of two companies: Leading Edge Management and Electrical Expert Inc., both in College Station, Texas. He is the author of Right-Brain Project Management: A Complementary Approach [Management Concepts, 2007] and From Engineer to Manager: Mastering the Transition [Artech House Publishers, 2002].

Even as the initial sales receipts for the first transistors to hit the market were being tallied up in 1948, the next generation of transistors had already been invented (see “The First Transistor and How it Worked.”) Since then, engineers have reinvented the transistor over and over again, raiding condensed-matter physics for anything that might offer even the possibility of turning a small signal into a larger one.
