The chief difference between a broad differentiation strategy and a focused differentiation strategy is

the degree to which the product is differentiated from the product offerings of rivals$--$a broad differentiation strategy emphasizes capturing the differentiation benefits of a large number of value drivers whereas a focused differentiation strategy concentrates on capturing the differentiation benefits of just one or two $($occasionally as many as three$)$ value drivers.

the number of differentiating attributes incorporated into the product offering$--$a broad differentiation strategy entails having many differentiating features and attributes while a focused differentiation strategy is concentrated on just a few differentiating features and attributes.

the size of the buyer group that a company is trying to appeal to$--$a broad differentiation strategy is aimed at many buyer groups and market segments and a focused differentiation strategy is aimed at appealing to the unique preferences and needs of a narrow, well$-$defined group of buyers or market segment.

the number of upscale attributes incorporated into the product offering$--$a broad differentiation strategy entails having a bigger number of upscale attributes than does a focused differentiation strategy.

the type of value chain being used to achieve a differentiation$-$based competitive advantage$--$a broad differentiation strategy requires a more complex and sophisticated value chain than does a focused differentiation strategy.
