Those who understand  BINARY and those who DON’T.”  TASK: 1. Create a new word processing document and save it as Binary Numbers. 2.

Our lead developer was recently certified in Scrum, one of the agile methodologies, and would like to try to manage this project using scrum.

In order for her to do this, she needs us to rewrite the requirements list you previously created as user stories. Just to remind you, a user story looks like this:

For example: As a taxi driver, I want directions so that I can quickly get to my next customer.

Please rewrite all of your requirements as user stories and I will pass it on to our development team.
