You are on a team that is developing a Web site for a local business, Custom Car Care. There is a set schedule of four months for requirements analysis, development, and successful deployment.

The team is on schedule, in week 8, and has just shown Debbie, the CEO of Custom Car Care, the prototype. Debbie is very happy with your work so far, but has some additional capabilities she would like added to the site. Although the additions are not in the previous time or cost estimate, she requires that you stay on schedule and within current budget. What do you do?
