10. Theresa Caragol
Vice President, General Manager, Global Business
Caragol began her tenure with Ciena six years ago. She recently led a nine-month initiative to overhaul Ciena's channel program after the completion of the Nortel MEN asset acquisition. Caragol's new program is "value-based" and rewards partners on a range of criteria in addition to how many products they sell. The improved program was designed based on feedback from partners and is aimed at providing them with streams of high-margin revenue.
