The Common Approach to Impact Measurement project is a new type of impact measurement standard for social enterprises. The lack of a standard measure impedes social enterprises from effectively telling its story, communicating with a wide variety of stakeholders and operating in a high impact manner. And yet, forcing all social enterprises into the same way of measuring their impact will also impede this ability. Between too little uniformity and too much uniformity is the sweet spot that the common approach will satisfy. The Common Approach to Impact Measurement project is building on great work already done by the social enterprise ecosystem, connecting it to cutting-edge globally recognized research.
