This is something that the large clients for legal services have been advocating for a while. It is generally called project based billing. Many legal fields operate more or less on project based billing nowadays, even if they technically operate on hourly billing. (Usually the billing is hourly but there is understanding about how long each project should take).
I think this is very dangerous and tends to reward mediocre work. But it is probably inevitable too, because in the legal field a large client will usually eventually get what he/she wants.
