Answer
Barnes & Noble could segment its company wide performance by individual store, by sales channel (i.e., brick-and-mortar versus on-line), and by product line (e.g. non-fiction books, fiction books, music CDs, toys, etc.). Procter & Gamble could segment its performance by product category (e.g., beauty and grooming, household care, and health and well-being), product line (e.g., Crest, Tide, and Bounty), and stock keeping units (e.g., Crest Cavity Protection toothpaste, Crest Extra Whitening toothpaste, and Crest Sensitivity toothpaste).
