According with the comments, looks like you are asking about the possibilities of automating repetitive jobs.
Human is falible. It's not good at doing repetitive and tedius things over and over. The more times it does something the more chances it has of failing. Here is where applications, as automated works, (or workflows) fit well.
Programms are good doing repetitive jobs. They don't get distracted, they don't get exhaust and if they are well implemented, they don't fail. Or in the worse case, they always do the same errors :-). And on top of this, they don't have payrolls.
They also are faster than us, what basically reverts in the consumer benefit. Consumers are provided with a service/product that generates predictive and faster responses.
The less time we spend doing an specific job, the more time we have to go shopping or to play video games.
Finally, it reduce the need of intermediaries. The interaction consumer - product/service is quite more straightforward and efficient. As you know, we humans sucks in communication, so the less intermediaries the better. And cheaper in the long run.
That being said, I have the feeling that you are probably asking about automate business processes. Humans workflows.
As I commented, some workflows are more administrative-like and they still may require intermediaries.
Here the final result of the process is not so predictive. The process still depends on the people doing their job. Like in the public administration.
This sort of automations are known as BPMS. BPMS allow us to computerize procedures that usually would take us to do manually and in person and that get involved different persons at different places and moments. These process still require some human activity like validations, confirmations, reviews, etc.
Think how we apply for unemployement benefits to the local administration. It require us to go to the local administration, wait for the turn, fill up a form and wait for the aproval. Then we have to be back for the renewval every month.
From the consumer point of view is a huge waste of time. From the guy/gal at the local administration office is an insane amount of work and papers.
Computerizing this workflow, the local administration allows citizens to apply for the benefits from home. Or from wherever they are. They also can check out the request's status (in process, waiting for aproval, aproved, rejected). Traceability we call it.
From the consumer point of view, automate workflows are seen as a time and energy savings. From the provider point of view, are seen as cost-cutting and reliable tools. They can make faster a business process that traditionally would take days or weeks to get done. The provider no longer need to send a messenger half way across the world to get the form X and wait for the best.
From everybody point of view, they allow us to focus on what matter. Anything but repetitive and tedius jobs.
