This question already has an answer here:
Recently, two guys contacted me and asked me to build their mobile app. They have a brand new concept and want an app quickly.
I told them that I need some user stories and some specifications by example in order to accurately know what they expect from the app and to be able to make an estimate of the tasks and delay (front + back).
They respond: "It's up to you to make the specification, YOU are the developer... We know nothing about coding you know? If you ask some questions about functional behavior, YOU have to ask us. We explained you the concept, now we have to wait for the app you would build"
What to think about this? Should I help them to specify what the app should do ?" Isn't it risky to work for a customer that doesn't know what exactly the app should behave regarding several use cases?
