Since the industrial revolution, most industries have sought to increase efficiencies and maximise profits through automating as much of their routine workflow as possible. Until the 80s and 90s, the majority of automation concerned physical processes, such as factory work. But once computers had become a more established part of professional workplaces, it was possible to start automating routine office tasks. Over the past decade or so, law firms have joined the automation revolution, adopting various forms of legal technology which allow them to leave various routine tasks to computer software.
