Model-View-Template separation pattern helps to maintain simple CRUD based logic. Viewflow is the library that offers an additional layer of django web framework, allows explicitly specify people's workflow and extracts collaboration logic from django views.

Viewflow layer is based on the BPMN - business process management and notation standard. It is the graphical notation readily understandable by all business stakeholders and software developers. Viewflow bridges the gap between a picture as the software specification and the working solution.
