CAP Model

The Change Acceleration Process model was developed by General Electric (GE) as a method to help influence changes in the business. GE learned that it's not enough to have the right solution, but implementing such a solution that involves change must be accepted by those impacted by that change; otherwise the change (and ultimately that solution) may fail. The model is based on the equation Quality x Acceptance = Effectiveness (or Q x A = E) which accounts for the multiplicative impact of acceptance (i.e., buy-in for the change) to influence how effective the final change will be.
