Kathy Iberle
Portland, Oregon


Katherine met Kathy Iberle in 2000, when they were both working for Hewlett Packard's Printer Group. They drove several major programs together before Katherine left HP in 2005 to start Whittier Consulting Group. They reconnected after Kathy left HP so that Katherine could leverage Kathy's Agile experience. Kathy supported one of the four major programs that led to the development of the Rapid Learning Cycles framework, and said at the time, "If this works — it's a breakthrough!" Seven years later, hundreds of companies have experienced breakthrough acceleration of time-to-market.
