About a week ago I finished a 5-day course for Microsoft SharePoint administration. SharePoint is a collaboration platform that encompasses functionality including content management, wikis, blogs, files sharing (including file check-in/check-out/versioning), workflow/BPM (Business Process Management), BI (Business Intelligence) integration with MS Outlook/Exchange, integration with other third party ERP (Enterprise Resource Planning) platforms such as Oracle and SAP via the BDC (Business Data Catalog), and an amazing search engine to crawl and index all of these data sources.
The convergence of all of this functionality into a single platform is aggressive. There is room for improvement in some of these areas. For instance a comparison of the document management in SharePoint may not quite be on par with Stellent but it's pretty good.
MindSharp is just a fantastic organization as well. If you need SharePoint Training I can't stress this enough: you need MindSharp. Ben Curry was the trainer for the class I took and he is the most knowledgible, dynamic, student-focused trainer I've ever had the pleasure of listening to. In addition to being a first class teacher his books on Microsoft Press are on par. His titles include Microsoft SharePoint Products and Technologies Administrator's Pocket Consultant and Microsoft Office SharePoint Server 2007 Best Practices (just published). In addition he contributed material to Microsoft Office SharePoint Server 2007 Administrator's Companion by Bill English (founder of MindSharp).
