What are a burn-up chart and a burn-down chart, and how are they used in the agile SCRUM process?

This is a technical question. It asks you to define a specific element of the agile methodology and discuss how you would use it. Keep in mind that technical questions are best answered succinctly and straightforwardly with little embellishment. You should also be prepared for follow-up questions.

"The burn-up chart depicts the amount of work already done on a project, whereas the burn-down chart shows the amount of work still required to do. These charts are used to communicate the status of a project. They also enable the developers to negotiate with the project owner for additional resources, time, or funding needed to complete the project."
