Facebook innovated its way to become the dominate social network with 600 million users in just six years since launch. What will it do for an encore? More importantly, how will it continue to innovate? For this month's LAB, we will apply the Attribute Dependency tool to demonstrate how Facebook might continue re-inventing itself. To use Attribute Dependency, make two lists. The first is a list of internal attributes. The second is a list of external attributes - those factors that are not under your control, but that vary in the context of how the product or service is used. Then create a matrix with the internal and external attributes on one axis, and the internal attributes only on the other axis. The matrix creates combinations of internal-to-internal and internal-to-external attributes that we will use to innovate. We take these virtual combinations and envision them in two ways. If no dependency exists between the attributes, we create one. If a dependency exists, we break it. Using Function Follows Form, we envision what the benefit or potential value might be from the new (or broken) dependency between the two attributes. Here are attributes of the Facebook experience:
