Quality  measures a product’s performance against its specifications now.  Reliability  is a measure of performance over time  [i.e., how long a device will continue  to perform within its specifications; and, even if it remains within its specifications, that it will be stable (i.e., drift  will not be an issue)].

Companies should be in business to satisfy customers’ needs (reasonable pricing for the on-time delivery of product that meets quality and reliability guidelines).  Assuming this is successfully accomplished, other things (profit, creative innovation, job creation & preservation, etc.) will, with the passage of time, fall naturally into place.
