What scenario causes innovation where new routing methods emerge?

Answer

When existing methods fail to handle new complexity

The progression of call routing technologies illustrates a clear pattern of evolution driven by the necessity to overcome limitations in existing systems. Innovation in this field occurs precisely when the established methods prove insufficient for handling increasing complexity in communication management. For example, when simple sequential distribution became overwhelmed under high call volumes, the need for a more mathematical approach led to the Vector-based approach. Similarly, when basic availability checking could not accommodate specialized customer needs, the concept of skill-based routing emerged to solve the specialization problem.
