patterns

We have requirement to build a new web application - order tracking application. Requirements are as follows.

1. Our application is just a consumer - not a source system
2. We have to consume a web service which will provide order details
(product and milestones for a specific product/ order)

3. The challenge we have is we have to build a framework which should allow showing the milestone details in the UI in a graphical way

- Milestone details are dynamic to some extent. i.e. That is there should be no change from our end when new milestone introduced
- Also there should be minimal / no change when new products introduced


Are there any techniques / design patterns used to build this kind of applications/ frameworks? When a new product us introduced, we should make that product available in the product-select drop down with minimal/no change. Also when an order is searched for - milestones should be rendered and coloured without knowing exactly how many milestones available for that product while doing required validations.

Appreciate your input here.
