Abstract: A management system and method providing a flexible, iterative approach for conducting strategic consulting and planning engagements as well as application-based and custom system development projects. The system and method are intended to provide a unifying framework to both communicate planning and delivery approaches to clients and to enable collaboration among various personnel called upon to deliver a client solution. In one embodiment, said method includes creating a decision inventory and business process flow, identifying and designing models to inform decision yield and business architecture requirements; capturing baseline decision yield information; and quantifying potential improvements to the decision yield to determine a decision yield value proposition with said quantifying being based at least in part on said captured baseline decision yield information.
