While CMMI adoption is supported by Government mandate, adoption of the CMM for Business Development (BD-CMM) draws heavily on an ROI model based on industry experience and benchmarking. During 2017, the Business Development Institute International conducted a global study to update and extend the model's ROI based on industry experience in 4 world geographies. This presentation will share top-level results from the study and demonstrate their applicability to the model's underlying CMMI maturity framework. Also, it will share how this benchmarking enables impact calculations of best practice on business ROI (including CMMI readiness) in markets and businesses around the world.
