First-contact problem resolution
Establish a one-contact resolution for customer issues
Explore whether a process can easily be used for additional products or services

Distribute tasks by interdepartmental interactions to enable or restrict involvement
Reduce the number of contacts with customers and third parties
If capacity is insufficient, consider increasing the available number of resources
