non-functional
Out of commission
Non-functional describes something that doesn't work or serve its intended purpose: The elevator has been non-functional for weeks.
In software development, non-functional requirements specify how a system should perform rather than what it should do—covering speed, security, reliability, and scalability.
Non-functional objects may be decorative rather than practical: non-functional buttons on a jacket sleeve.
