It has always been my pleasure and fun to facilitate workshops for PM (product management) community at and outside Cisco, although this was first time I did a BDD workshop with PMs alone. And I realized today how PayPal has been a really great venue for SVPMA annual product camp "unconference" for 1k+ PMs with 550 waitlisted this year! I look forward to this event every year now...huge success!
Synopsis: As PMs, we should be driving innovation thru' those fuzzy ideas in terms of scenarios you always think about. Talk about those to your engineering teams or even peer PM/POs, and you see those diverging ideas converging to something concrete. That's how BDD helps you shape that idea. That fuzzy scenario, when validated thru' an engineering "spike", can be useful for your MRD/PRD/use-case-models/stories...whatever it is that you want to use to drive the product development. Go for it! So instead of doing top-down or bottoms-up product management, try this inside-out approach.
My workshop on BDD is about what I term as "Outside-in agile product management". To understand what I really mean by that, here is my slideshare presentation used rarely when teaching from the back of the class during this hyper-interactive workshop.
