This document discusses guidelines for revitalizing declining or dead brands. It begins by providing an example of Oldsmobile, which lost its identity as an innovator and ultimately died. It then discusses factors that can lead to brand decline, such as poor product quality, price increases/cuts, brand neglect, and an inability to stay relevant to the target market. The document explains how brand equity is diminished when the differential effect, brand knowledge, and customer response are negatively impacted. Finally, it offers four guidelines for revitalizing brands: determining if the brand is worth reviving, taking a long-term perspective, carefully repositioning and investing in the brand to educate the market, and correcting any past mismanagement.
