As electronic product designs age, component parts become increasingly difficult to obtain. Component buyers may experience difficulty in obtaining key parts within the design. Component part prices may increase. A point comes when component parts begin going end-of-life at an alarming rate. Quick fixes are no longer sufficient. Sometimes an OEM will procure a 'life-time' supply of problem parts – but this supply can be quickly wiped out should unforeseen demand develop. Lack of component parts puts an end to production.There is an alternative. Profitable, old products can be redesigned. Either preserving the original form fit and function, or adding new features. Product redesign is a cost effective means by which to extend the life of a marketable product.
