When It comes to brand identity, The Home Depot is a perfect example. The Home Depot has The Home Depot Foundation and Team Depot. Some of their national partners include Habitat for Humanity International, the American Red Cross and Team Rubicon. This makes sense, they're one of top American "do it yourself" (DIY) home improvement supply retailing companies that sells tools, construction products, and services. Focusing on disaster relief and building communities connects to their brand identity and the resources they bare. I imagine focusing on unrelated cause-areas would be a mistake.
