What's the Discovery Phase?

It's mostly at that point it's kind of just the problem of scoping paired with the technology stuff you're talking about. Yeah, and then what you've got through that discovery phase you found a problem we think it can be solved. We understand broadly speaking what a kind of high level solution might look like and what it might take to do it. Can you walk us through the next phase of the design what does that design process look like? I don't know if there are any other things in that sort of discovery phase that you're looking out for in particular. Nothing I can think of that we haven't talked through.
