The CIA wrote a manual on how to do this. It’s a bit old and parts of it are outdate for some times of work, but a lot of it is still useful.

• Misunderstand orders. Ask endless questions or engage in long correspondence about such orders
• Insist on perfect work in relatively unimportant products
• Hold conferences when there is more critical work to be done (some might say normal businesses do this as a matter of course…)
• Bring up irrelevant issues as frequently as possible
