The document discusses knowledge work and knowledge workers. It defines knowledge work as work based on cognitive skills that results in intangible outputs through information processing and creativity.

The term "knowledge work" was coined by Peter Drucker in 1973 to describe the most valuable asset of 21st century institutions. Characteristics of knowledge workers include continuing innovation, self-management, and being viewed as an asset rather than a cost. Types of knowledge work include diagnosis, planning, monitoring, organizing, authoring, and system development. Technology such as personal computers, networks, and intelligent workstations support knowledge work.
