seemingly routine, but that require deeper technology, product, or customer knowledge to fulfill the function. These include: providing technical or customer support handling unique customer issues addressing open-ended inquiries Generally, if the knowledge can be retained, knowledge worker contributions will serve to expand the knowledge assets of a company. While it can be difficult to measure, this increases the overall value of its intellectual capital. In cases where the knowledge assets have commercial or monetary value, companies may create patents around their assets, at which point the material becomes restricted intellectual property. In these knowledge-intensive situations, knowledge workers play a direct, vital role in increasing the financial value of a company. They can do this by finding solutions on how they can find new ways to make profits. This can also be related with market and research. Davenport (2005) says that even if knowledge workers are not a majority of all workers, they do have the most influence on their economies. He adds that companies with a high volume of knowledge workers are the most successful and fastest growing in leading economies including the United States. Reinhardt et al.'s (2011) review of current literature shows that the roles of knowledge workers across the workforce are incredibly diverse. In two empirical studies they have "proposed a new way of classifying the roles of knowledge workers and the knowledge actions they perform during their daily work." The typology of knowledge worker roles suggested by them are "controller, helper, learner, linker, networker, organizer, retriever, sharer, solver, and tracker": Additional context and frameworks Drucker (1966) defines six factors for knowledge worker productivity: Knowledge worker productivity demands that we ask the question: "What is the task?" It demands that we impose the responsibility for their productivity on the individual knowledge workers themselves. Knowledge workers have to manage themselves. Continuing innovation has to be part of the work, the task and the responsibility of knowledge workers. Knowledge work requires continuous learning on the part of the knowledge worker, but equally continuous teaching on the part of the knowledge worker. Productivity of the knowledge worker is not — at least not primarily — a matter of the quantity of output. Quality is at least as important. Finally, knowledge worker productivity requires that the knowledge worker is both seen and treated as an "asset" rather than a "cost." It requires that knowledge workers want to work for the
