Without saying the words, Jeanne Liedtka, Professor of Business Administration, Darden School of Business, University of Virginia and Co-Author, Designing for Growth: A Design Thinking Toolkit for Managers (Columbia Business School Publishing) discusses the Job to Be Done metaphor. Listen to this short talk she gave at Rotman School of Design.
Her co-author, Tim Ogilvie, CEO of innovation strategy consultancy Peer Insight was a past podcast guest and I highly recommend both the podcast and the book. Both are favorites of mine.
