Products should be designed to be maintained in good condition. Most products cannot be maintained and simply run until something goes wrong and are then discarded. Maintenance is vital in maintaining performance and increasing the lifespan of products. Designers should attempt to minimise the amount of maintenance required, but make any maintenance that is required easy and cost effective to carry out. The product should also be designed in a way that encourages the user to keep the product properly maintained.
