Methods of determining optimal staffing distributions include receiving input, wherein the input includes a first workforce constraint and a second workforce constraint; identifying a plurality of values for the first workforce constraint; determining, for each identified value for the first workforce constraint, a combination of the plurality of agent groups that provide the identified value for the first workforce constraint; selecting, for each identified value for the first workforce constraint, a combination of the plurality of agent groups from the determined combinations, that provides an optimal value for the second workforce constraint; generating an optimal line; displaying the optimal line on a graphical user interface; receiving a selection of a point on the optimal line; and applying the selected point to a staffing distribution plan.
