Business Process Automation
There are many activities executed by business users that are in fact routine tasks without much of added value from humans. Those can often be automated by SW robots eliminating time to complete, error rates and human effort in general.
In cases standard migration techniques are not applicable and manual migration becomes an option, SW robots come in handy, for example in situations when you need to replace legacy system with a new one.
It is always best to integrate two applications in a conceptual way. Long time to complete however do not often comply with business owner needs. RPA might be a good temporary solution in such a case.
Robot can also help execute application regression testing which is often too complex and tedious for business users to perform.
