Foundational free Patterns
Assign a responsible individual for handling each case type
Determine whether activities are related to the same type of case and, if necessary, distinguish new business processes
If capacity is insufficient, consider increasing the available number of resources
Order knock-outs by least effort and highest termination probability first.
Consider whether activities may be executed in parallel
Start implementing actions that can offset or counterbalance the environmental effects generated by business processes that cannot be changed.
Automate for environmental impact
Implement automation in a sustainable way
Expertise-based task assignment
Match tasks to experts' specialized skills for efficiency
Delegate tasks according to resource cost
Reduce the number of contacts with customers and third parties
If capacity is insufficient, consider increasing the available number of resources
