Design Sprint -Interaction Design Foundation

Hi everyone! to be honest, I haven't work with those modern metodologies and since I have read an article*, I was a kind of insure about it.

So I attended to a Design Sprint , that was made by IDF mentors (https://www.interaction-design.org/) and a well-know bank here in Perú (BCP). They explained the metology and made us to solve a bank problem, ask for users at streets and prototype with paper.

My impression was that everything was very rush and It will works if you want to get involved stakeholders that doesn't understand what UXers does.

Everything was cool , however I'm still thinking if it really works. Maybe a pair of conference or a meetup with collegues will solve my doubts.

What do you think about it? Does it work for you? Do you have a kind of difficulties?

Let me know!
Thanks for the support!
