Foundational free Patterns
Assign a responsible individual for handling each case type
Empower workers for more decision-making authority
Delegate and optimize your operations
Consider to deepen or broaden the skills of resources
Collect similar work items and work in batches
Execute tasks when the grid is powered by renewable energy
Start implementing actions that can offset or counterbalance the environmental effects generated by business processes that cannot be changed.
Experience-based task assignment
Delegate task according to experience: execution frequency, case involvement, interactions
Allocate task based on collaborative experience: handover time, interactions, diversity
Reduce the number of contacts with customers and third parties
If capacity is insufficient, consider increasing the available number of resources
