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!
As Product Owners and Managers are driving innovation thru' those fuzzy ideas in terms of scenarios, testers have always been thinking about those in form of test cases which take form of acceptance criteria for those scenarios. When you talk about those scenarios to your teams or even peers, 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 product management MRD/PRD/use-case-models/stories...whatever it is that you want to use to drive product development.
And this is where Agile Tester role begins! So instead of doing top-down or bottoms-up product management & testing, try this outside-in approach. Go for it!
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.
