A couple that come to my mind are the legal and pharmaceutical fields. Yet even then, with all the details about just how and why a decision was made, or all the conditions surrounding a clinical trial, the resulting documents still focus only on the explicit aspects of the topic. Contrast this with the works of the novelist or essayist and we see one reason why the two forms of documents are so easily distinguished. They do this through numerous methods, all available to, but rarely used by, today's technical authors. Document managers can not solve these issues alone.
Help is needed from many other aspects of the business community.
It could mean developing authoring environments that lead our technical authors to think about the tacit aspects of the knowledge they are trying to convey. It might mean providing tools that would help us uncover and document the explicit triggers to tacit knowledge. Or maybe it just means that we need to rekindle the understanding that there really is a set of distinctive skills that make a person a good communicator, writer, or author. However, there is more to the knowledge life cycle than just the creation phase. We also need to enhance our understanding of how knowledge contained in documents is retained, maintained, transferred, and made useable.
