The practice of designing and building solutions for specific, often temporary situations—engineering without the luxury of planning, testing, or mass production. Ad hoc engineering is what happens in emergencies, in remote locations, in startup offices, in any situation where you need something to work now and can't wait for proper engineering. It's the art of the temporary fix, the makeshift solution, the structure that only needs to stand for a while. Ad hoc engineering is despised by professional engineers (who value reliability) and beloved by everyone else (who value results). It's engineering for the real world, where most problems are unique and most solutions are temporary.
Example: "She practiced ad hoc engineering in her apartment, building a bookshelf from cinder blocks and planks, a desk from a door and sawhorses, a headboard from an old fence. Nothing would survive a move; everything worked perfectly here. Ad hoc engineering wasn't permanent, but it was home."
