Business philosophy

Weeks has said that "If you’re going to sustain as an institution, you have to focus on problems that matter. For Corning, some of those things are cleaner air; safer, more effective medicines; and fast, reliable communication. A company’s value is ultimately measured by whether or not it does good in society." He believes that creative destruction is an important part of capitalism, but so is collaboration.^[7] He regards failures as opportunities to learn.^[8]
