Thanks for sharing. Some of the more progressive thinkers in our space are exploring this model right now, so I'm not surprised T+L is as well.
Bob Moesta regularly does interviews about JTBD, but recently Ryan Singer has as well, with 37Signals hosting some of the JTBD Switch workshops in Chicago. Ryan Singer had a great interview with Des Traynor on the Inside Intercom blog.
If folks are interested in this methodology, they should listen to the interview Bob Moesta had with Horace Dediu on the Critical Path a few years back, and/or check out the online course on the subject on Coursera / Udemy (one of those online learning platforms).
