We’re revisiting Shape Up and product development thoughts with Ryan Singer, Head of Product Strategy at Basecamp. Last August we talked with Ryan when he first launched his book Shape Up and now we’re back to see how Shape Up is shaping up — “How are teams using the wisdom in this book to actually ship work that matters? How does Shape Up work in new versus existing products?” We also talk about the concept of longitudinal thinking and the way it’s impacting Ryan’s designs, plus a grab bag of topics in the last segment.
