Answer to Question 2
Extraordinary leverage and increasing returns. Knowledge is not subject to diminishing returns. When it is used, it is not decreased (or depleted); rather, it is increased (or improved). Its consumers can add to it, thus increasing its value.
Fragmentation, leakage, and the need to refresh. As knowledge grows, it branches and fragments. Knowledge is dynamic; it is information in action. Thus, an organization must continually refresh its knowledge base to maintain it as a source of competitive advantage.
Uncertain value. It is difficult to estimate the impact of an investment in knowledge. There are too many intangible aspects that cannot be easily quantified.
Value of sharing. It is difficult to estimate the value of sharing one's knowledge or even who will benefit most from it.
