Knowledge management refers to practices and strategies companies use to create, distribute, and enable adoption of strategic insights and experiences. Knowledge is a competitive advantage as organizations that learn faster than competitors get ahead and stay ahead. Key trends impacting knowledge management include digital engagement, cognitive analytics, social activation, and industrialized crowd-sourcing. Knowledge management relies on three building blocks - knowledge sharing processes, an environment conducive to sharing, and leadership that fosters these.
