The BVI Framework
The advantage of a framework nested within an overarching model is that it allows flexibility for those tasked with its practical implementation. As long as the conceptual model is recognised, then actual delivery of any one aspect is not prescribed or required. Anyone using the BVI Model should feel free to rename or revise the functional parts in the Framework to suit local needs or to aid cognition or acceptance in their organisation or community.
The model-to-framework approach also accounts for the range of fuzzy elements within an assessment of impact. A high-level conceptual model allows for the thinking, context and perception to be represented, while the Framework allows the products of this thinking to be controlled, contained and then utilised.
