The results chain logic model clearly identifies the linkages from inputs to activities through associated outputs to the sequence of expected outcomes. Inputs and activities are identified to the left of the process as being within the area of control internal to the organization, and outputs are identified as products or services reaching an external group. To the right is the area of influence external to the organization in which immediate, intermediate and final outcomes are identified. This is where external factors are also identified as having influence or effect. Below the model areas of efficiency and effectiveness are also identified with efficiency taking place during the inputs, activities and outputs steps and effectiveness beginning during outputs and continuing through to the final outcome.
