1. Evidence of substantial corporate spending on IT for knowledge management has been well documented. Companies spent $2.7 billion in 2002 on knowledge-management software, with document-and content-management software capturing the top share. Worldwide spending on knowledge-management services totaled $2.6 billion in 2001, much of it on documentation efforts. The software market is expected to increase to $4.8 billion in 2007, and spending on services is expected to increase to $4.6 billion in 2004. In addition, 85% of the Global 2000 are expected to have selected a portal platform by the end of 2004. Employee portals represented companies’ largest expected software spending priority in 2003, with content and document management remaining a close second. Sources for these figures: S.

2. Many approaches to creating more value from knowledge have been addressed in the management and academic literature. These include transferring and applying tacit knowledge and expertise; acquiring, creating and codifying new knowledge; and organizing existing knowledge, both tacit and codified. We focus on a subset of these issues — knowledge that has already been codified and placed in a repository. This knowledge represents significant sunk costs by organizations that we believe could be made much more valuable with incremental investments. The management of codified knowledge has been discussed in M. Zack, “Managing Codified Knowledge,” Sloan Management Review 40 (summer 1999): 45–58; R. Cowan, P.A. David and D. Foray, “The Explicit Economics of Knowledge Codification and Tacitness,” Industrial and Corporate Change 9 (2000): 211–253; and R. Cowan and D. Foray, “The Economics of Codification and the Diffusion of Knowledge,” Industrial and Corporate Change 6 (1997): 595–622. However, little attention has been given to the relationship between codified knowledge and knowledge-worker productivity in particular and to illustrating by analogy the ways in which nonintuitive case studies have relevance for managers trying to increase the value of their organizations’ documents.
3. An implicit assumption is that existing documents represent some or most of the codified knowledge a company would want employees to find and apply. If this were not the case, organizations would want to devote more time to identifying, codifying and prioritizing the most important knowledge.
4. These actions build on the significant contributions in the literature to the design of information- and knowledge-based products, including M.H. Meyer and M. Zack, “The Design of Information Products,” Sloan Management Review 37 (spring 1996): 43–59; and the more popular views of information design by E. Tufte (all published by Graphics Press, Cheshire, Connecticut): “The Visual Display of Quantitative Information” (2001), “Visual and Statistical Thinking: Displays of Evidence for Decision-Making” (1997), and “Envisioning Information” (1990).

6. EBay is similarly successful helping customers qualify potential sellers, which is critical given that their business model is based on trust. Every eBay member has a profile with basic information about the member and a list of feedback left by their trading partners from previous transactions. Learning to trust a potential seller (or buyer) has a lot to do with what their past customers or sellers have said about them. For each transaction, only the buyer and seller can rate each other by leaving feedback, which consists of a positive, negative or neutral rating and a short comment. The feedback gives other eBay shoppers and sellers a good idea of what to expect when dealing with that person.
7. Consider an example: If average employee salaries are $80,000 and an employee searches for knowledge on average twice daily, then a five-minute savings in search time could result in 40 hours of time saved over the course of a year per employee (assuming 240 working days). This represents over $15 million for an employee base of 10,000 workers and 400,000 hours of time that could be better spent on more productive activities than searching for knowledge.
