System throughput is the ability of the organization to produce value over a period of time.
Every value stream of the organization is dependent on the throughput of the system. It is limited to the capacity to deliver one unit in x-number of units of time in a given phase. The smallest capacity of the value stream is also referred to as a bottleneck and is crucial to be identified and removed to open overall organizational productivity. It is well-described in the theory of constraint.
System throughput of the enterprise determines the velocity with which the organization is capable of delivering the value through acquisition>integration>change management of the practices. Ultimately, system throughput is the most important factor that will determine the ability of the organization to execute on the entire Value Creation Plan (VCP). Without clear throughput, the organization may fail to raise capital towards the goals outlined by the Board of Directors.
