But the machine wasn’t a steam engine: it was an office copier. Watt realised that copies of his letters would be very useful to others and so he invented a machine that transferred damp ink from a freshly written letter to another sheet of paper, creating a copy of it. The instructions included are in their most basic form. They say to take a sheet of paper, put it on top of the other sheet of paper. Put the felt blanket on top. And put it through the rollers. “As James Watt was a very practical man, the instructions are not a booklet,” Bridgman told a 2009 BBC radio documentary, How to Write an Instruction Manual. “They are actually a sheet of paper glued to the machine so you can’t lose them – a rule that modern manufacturers could do well to emulate.” In fact, for Ballard, Watt’s instructions exemplify a successful manual’s fundamental principles. The first is “findability”: making it easy for people to find the information they need, whether that means being able to find the manual itself by putting it in an obvious location or having an intuitive structure that has anticipated the way the reader thinks about their problem. The second is making the instructions easy to understand. “Clarity will win every time,” says Ballard. Simplicity and directness in both language and design is key. The final rule? “Get out of the way,” Ballard says. This means making sure people know what to do next when their particular need has been met – whether that is finding out something else or cracking on with using the product. This, Ballard jokes, is why instruction manuals face an “existential crisis”. “The whole point is the product, not the manual; the more you're spending time looking at the manual, the less you're getting out of the product.”
