However, technology marches on, and eventually teams might decide to reposition a product on the perceptual map. When the revision project completes, the product's age will be cut in half. The "new, improved" revised product is not as dated as the original, but it is not brand new either. Customers perceive the age to be half of what it was just prior to the revision.

Just changing MTBF, however -without changing the product's size or performance -does not affect its perceived age.
