This report provides detailed guidance on proving your emerging technologies’ research and evaluation efforts as part of our ReCPI framework. We break prove work into three components with different objectives: 1) proving the capabilities and maturity trajectory of the emerging technologies involved with an opportunity; 2) evaluating the fit of an opportunity with your firm’s culture and talent; and 3) evaluating the fit of an opportunity with your firm’s processes and architecture. For the prove component of the ReCPI framework, we provide specific work objectives, activities, and outputs.
