A reusable workflow can be packaged up as a workflow template and moved to a different site collection. The package is a workflow solution file with a .wsp extension. This file is deployed to the solution gallery and then activated so it can be used at the other site collection. The procedure is demonstrated in this video.

SharePoint Server ships with several built-in workflow templates to be utilized right away. As a site administrator, you can use any of these templates to create a new unique workflow for any list or library on your site. Most of these templates are exposed and available to be modified as needed using SharePoint Designer 2010. This video shows how you can modify the Approval workflow template to your needs.

You can publish a reusable workflow globally to a site collection. Once published, the workflow is then available throughout the site collection and can be used at any site. This video shows how easy it is to create this type of workflow.

SharePoint Designer workflows automatically generate forms as needed to interact with participants of the workflow. If you are running SharePoint Foundation, these forms can be modified using SharePoint Designer itself. However, if you are running SharePoint Server Standard or Enterprise, the forms generated are automatically InfoPath forms. If you have InfoPath 2010 available to you, you can use it to modify these forms and use all types of powerful functionality available in InfoPath such as data validation, conditional formatting, and action rules.

If you are running SharePoint Server 2010 Enterprise, you have the capability to visualize any running SharePoint workflow. The visualization appears in the workflow history page and shows you the current status of the workflow. This process is supported by Visio Graphics services which ships with SharePoint Server Enterprise. This video shows how this visualization works.

Visio Premium 2010 supports modeling a SharePoint workflow. This functionality is not available in Visio Standard or Professional. A business or process analyst can model a workflow in Visio then hand it off to a developer, power user or site administrator to configure and deploy the workflow in SharePoint Designer 2010. This process can work the other way around as well. You can take an existing workflow in SharePoint Designer 2010 and export it to be viewed in Visio Premium 2010 without any loss of functionality or settings.

SharePoint Designer can be used to create powerful workflows on your site. You can create workflows on a list or library, create reusable workflows or create site based workflows. This video focuses on creating list workflows. While showing you how to create a list workflow, the various capabilities of the workflow designer environment (such as steps, conditions, actions, parallel branching, moving actions around etc) are explained so you can take full advantage of this robust environment.

Being able to create reusable workflows is a major component of SharePoint Designer 2010. In this presentation, you will see how you can create a reusable workflow and attach it to a content type and then use that content type in a library.

One of the types of workflows you can create using SharePoint Designer 2010 is the site workflow. This type of workflow is not attached to a list or library but rather to a site itself. In this video, you will see how to accomplish that. In addition, you will also see how to modify the user interface form, that this workflow creates, using InfoPath 2010
