Compare these two very different mission statements: (a) An organization with five people said that its mission was "to eliminate hunger in the world." (b) Actor and social entrepreneur Brad Pitt, appalled by the sorry progress of rebuilding in New Orleans after Hurricane Katrina, started a nonprofit organization with a mission "to build 150 affordable, green, storm-resistant homes for families living in the Lower 9th Ward." What are the strengths and weaknesses of each mission statement?
