Abstract: A model and method for channel-based workforce sourcing is provided. In one aspect, a computer model is populated to create a baseline capacity, including a current number of resources in each of a plurality of skill, sets for each of a plurality of available channels. The computer model is also populated with one or more modulators that affect business-defined values. A desired channel mix, for example, for a given time period may also be recommended and specified in the model. The model is validated and updated with additional or new information. The model and method then automatically generates a starting headcount based on the baseline capacity and ending headcount based on the one or more modulators. The model and method may also generate a targeted plan over a given period for achieving the ending headcount from the starting headcount according to desired channel mix.
