SharePoint Designer 2010 Workflows with InfoPath 2010 forms and Visio Modeling
InfoPath forms are a great way to capture information from a user. They can be presented to the user as a web form right within a SharePoint site. User can fill out the form and it gets submitted to the form library in your site. The form library then has the capability to route that form for approval using a workflow. SharePoint Designer can be used to create that workflow. Workflows can also be modeled in Visio and then transferred to SharePoint Designer. All of this and more is demonstrated in this video.
