At this point, you have analyzed your needs and decided that building a site is what you need to do. Now it is time to identify the requirements that define the details of your site.

Requirements, coupled with your design plan, will give you what you need to create a list of criteria that you can use to confirm that Drupal is the right solution for you. You can use the requirements to verify and validate you got what asked for. Without clear requirements to set expectations, you run the risk of not getting the site you need.
