1. An Enterprise-wide Value Chain Management (EVCM) system comprising: an interface unit; a value computation unit to interact with a pluralities of entities in an organization through the interface unit to track an activity occurred between the pluralities of entities in real time to compute a value generated through the activity occurred between the pluralities of entities; a value measurement unit coupled to the value computation unit to process and monitor a flow of the measured values across the organization to detect a value generation, a value absorption and a value consumption and a value leakage at any point in an entire value flow; a reporting unit connected to the value measurement unit to receive and report an output of the value flow analysis unit to management to monitor a performance of the organization at multiple levels of value flow and transfer; wherein the multiple levels of value flow includes a process level, an entity level and a policy level; and a value optimization unit to ensure that value flow disruptions are tracked and trigger right corrective actions by interfacing with the entities.
