A parameters modification system for a contact center is provided. The parameters modification system includes an input module for enabling a user to provide an input indicating one or more parameters required to be modified. The parameters modification system further includes a determination module for determining a surface based on key performance indicators (KPIs) associated the one more parameters. The determination module further determines an optimal path in the determined surface. The parameters modification system further includes a modification module for modifying the one or more parameters along the determined optimal path so that key performance indicators associated with the one or more parameters remain within a predetermined threshold.
