A manufacturer of cupboard hardware is reviewing sales figures to determine whether or not to standardize its sliding drawer hardware. Research indicates that there are two lengths that are widely used, with other lengths ending up as surplus inventory. The manufacturer sells its product to kitchen cupboard and furniture manufacturers all over the world. The hardware is an innovative product, a result of a year of research that was launched a year ago. The manufacturer has not yet realized its return on investment. It is easy to install, and is a durable and quiet closured with very few service requirements. What would be the disadvantage for the manufacturer to only provide two standard lengths of drawer slides?
