The basic premise of Scrum is to help in developing complex software through an incremental and iterative approach based on regular feedback. The feedback comes from sprint review as part of the Increment inspection. That may translate into adaptation in Product Backlog if needed. Agile manifesto has a key tenet around change, i.e. “Responding to change over following a plan”.

Is it even possible to work in a fixed price Agile mode? If so, how?
This post outlines the most common challenges in executing fixed price Agile projects. It also suggests ways to handle them.
