Business requirements analysis during Production release

It's impossible to underestimate business analysis impact on product success -- we need to know what end user need and we must provide it to them. However it's very often that we see how 'simple business enhancement' turns out to be 'full system architecture review'. The idea of this lightning talk is not to argue about the reasons but rather show some examples of these 'false easy' changes and ways of fighting them in the face of upcoming release.

Requirements analysis is critical for product development success and knowing how to do it right will allow to prevent a lot of issues from happening.
