K2
The K2 platform is workflow and BPM software for automating enterprise business processes.
Built on .NET and deeply integrated with SharePoint and other technologies, K2 replaces the complexity of traditional software development with easy-to-use, visual tools — enabling business people and technical people to collaborate and assemble process-driven.
K2 also provides a Case management framework for SharePoint through which organizations can leverage SharePoint to increase efficiency, reduce mistakes and improve customer experience, while at the same time manage the increased burden of regulatory control.
