Product	Overall Ranking	Notes
K2.net 2003 Enterprise Workflow	8	Currently the K2.net product best fits our business requirements.  This product provides a full set of built-in workflow actions that tightly integrating with SharePoint, Microsoft Office (including InfoPath), Exchange, etc.
Ascentn BPM System	7	The Ascentn product by far has the best workflow designer of all the products evaluated; built directly into Visio.  This provides a tool many users are familiar with which may reduce training and education needs.  Ascentn was able to demonstrate integration with InfoPath but no other Microsoft Office integration "out of the box".  Built in SharePoint workflow action types are limited.
Skelta Workflow.NET 2004 with SharePoint Accelerator	5	The Skelta product provides a full set of built-in workflow actions that tightly integrate with SharePoint, Microsoft Office (including InfoPath), Exchange, etc.  I found the workflow administration features to be limiting; workspace administrators can create and deploy workflows without any approval by IT.
Captaris Business Process Workflow	4	The Captaris product has a very nice workflow designer UI with an integrated debugger.  This is the only product I have evaluated that has the integrated debugging feature.  Unfortunately the workflow action feature set is limited and requires development for most common tasks.  Limited "out of the box" reporting also requires development in every step of a workflow process.
Ultimus	N/A	This product was ruled out because it does not support any direct SharePoint integration features; or that information was not provided on their web site.  From the information I was able to find, this product was geared more towards a development environment.
