Figure 2. Knowledge work. (Davies & Naumann, 1997. 9 & Davies, 2002. 68)

With Bereiter’s knowledge work definition one problem can be raised: For example if you are working with combustion engine to improve horse power, are you working with concrete artifact or conceptual artifact, in other words, are you working with concrete engine or conceptual horse power? Davies definition relies on the input, output and methods. Key factor in the definition is the output – the product of the knowledge work, which is useful information or knowledge.

2.2KNOWLEDGE WORKER DEFINITIONS Ware & Degoey (1998) say that there are very little understanding how knowledge workers actually use information technology, or how information technology impacts knowledge worker performance and productivity. Knowledge work itself is poorly understood. There are many different kinds of tasks that are loosely called knowledge work. (Ware & Degoey, 1998)

Bereiter (2002) defines knowledge worker:

Knowledge workers create, improve, find new uses for, or otherwise add value to conceptual artifacts.

The skills and other kinds of knowledge needed in knowledge work depends a great deal on what particular kinds of conceptual artifacts are dealt with. (Bereiter, 2002. chapter 6)
