Hi,
HWS is not one of the best features of BizTalk, it will be present in 2006, but maybe not after that. There’s a few other options for building human workflow solutions with Microsoft Technology:
BizTalk + SharePoint + Office (InfoPath)
You can build a human workflow application very easily with these technologies, you don’t get the full featureset of a human workflow product unless you implement it yourself, but for simple scenarios, it’s a good option.
Windows Workflow Foundation (WF)
WF is worth looking at, you don’t have the enterprie hosting that BizTalk povides, but if you don’t need that (messaging, adapters, BAM etc.) it’s an option. The disadvantage is it’s only in beta at the moment.
Third Party Products.
K2 (http://www.k2workflow.com) has a workflow solution that allows you to build an advanced workflow solution on top of the Microsoft products (BizTalk, SharePoint, Office etc.). Worth looking at if you need a powerful solution.
Regards,
Alan
