5.1 QUESTION ASKING AND ANSWERING
Question asking and answering is a foundational process by which what people know tacitly becomes expressed, and hence, externalized as knowledge. To support such a view, we borrow from speech acts theory [Searle, J., 1969] that amongst others categorizes question asking as a form of a speech act. In adapting the theory, Hirschheim et al. [1995] describe types of speech acts that pertain to aspects of either Knowledge Management (KM), or Information Management (IM). For example, Boahene and Ditsa [2003] suggest that Information Management systems target a base of expressive speech acts by mainly supporting the recall of meaning-attribution while Knowledge Management systems target regulative and constantive speech acts primarily to support the organization
and management of dynamic complexity.
They reason that IM addresses questions such as ‘Where,’ ‘Who,’ ‘When,’ and ‘What,’ while KM targets problems involving dynamic complexity, addressing solutions to questions such as ‘How’ and ‘Why.’ Quigley and Debons [1999] adopted a similar stance that considers information as texts that primarily answer ‘informative’ questions such as who, when, what, or where while knowledge is considered as texts that answer more ‘explanatory’ or ‘meaning related’ questions such as why or how.
Another category of questions, “What-if,” will also fall in the domain of knowledge activity. Since such questions necessitate predicting and prioritizing outcomes, attempts to address such “what-if ” questions will require integrating understanding of “what” with “why” and “how” to arrive at reasonable resolution.Thus, what-if questions, primarily seen in the decision making domain, will likely call for exhaustion of all possible scenarios in order to arrive at any “best” alternative.

5.2 POSTING CONTENT TO REPOSITORIES
Contributing content such as lessons-learned, project experiences, and success stories is another approach to knowledge sharing. The capturing of best practice has often been highlighted as a form of externalized knowledge. O’Dell and Jackson [1998] point out the importance of frameworks for classifying information.
For many professionals who are used to online communication and accessing databases and discussion lists, we could argue that it is quicker and easier for the professionals to make the contribution themselves. Nick et al. [2001], noting the importance of learning by experience, point out that experience bases can be developed using case-based reasoning as the underlying concept. However, they also note that experience repositories require continuous maintenance and updating in order to handle continuous streams of experience.
Selvin and Buckingham [2002] describe a tool, Compendium, that claims to support rapid knowledge construction.They ground their claim on an empirical case study of its use in a corporate contingency planning situation by demonstrating the creation of knowledge content in a real time ‘on-the-fly’mode of content authoring, complemented by collaborative validation.
The developed content is then made available to others for (re)use, or, for re-combination, to support newinstances of knowledge creation. Richter et al. [2004] describe a functionally similar tool, TAGGER, designed and operationalized as allowing knowledge acquisition discussions to be “tagged” in real time with the relevant concepts so as to lessen the burden on documentation. As awareness increases for the importance of making knowledge explicit, more and more products will appear to help with creating knowledge bases and decision recommendations, but it is a mindset open to using, sharing, and creating knowledge that will make a difference in creating an organizational knowledge culture.

5.3 (RE)USING KNOWLEDGE
Desouza et al. [2006] assert that the decision to consume knowledge can be framed as a problem of risk evaluation, with perceived complexity and relative advantage being identified as factors relating to intentions to “consume” knowledge. However, it is essential that the knowledge consumer is able to reasonably frame his or her knowledge needs. Belkin et al. [1982] found that during problem articulation, users have anomalous states of knowledge, and they may not be able to specify their information needs accurately. Since the publication of this seminal work legions of researchers have worked on systems that will help people formulate effective questions that will retrieve relevant formation.McMahon et al. [2004], studying team work involving engineering design, suggest that both codification and personalization approaches to knowledge reuse are relevant. They recognize the notion of information value, allowing for the matching of information to the knowledge needs of the user. They propose that good representations of both information characteristics and user characteristics are essential.

5.4 KNOWLEDGE-BASED DECISION MAKING
In general, decision making involves identifying alternatives, projecting probabilities and outcomes of alternatives, and evaluating outcomes according to known preferences and implications for stakeholders. Choo, C. [2002] suggests that decision making activity requires the establishment of shared meanings and the assumption of prior knowledge.
Shared meanings and purposes as well as newknowledge and capabilities, converge on decision making as the activity leading to the selection and initiation of action.Shared meanings, agendas, and identities select the premises, rules, and routines that structure decision making. New knowledge and capabilities make possible new alternatives and outcomes, expanding the range of available organizational responses [Choo, C., 2002, p. 86]. Choo further proposes that information flows are a central process that bridges knowledge creation and decision making activity. Information flows continuously between sense making, knowledge creating, and decision making, so that the outcome of information use in one mode provides the elaborated context and the expanded resources for information use in the other modes [Choo, C., 2002, p. 85].
Information used in one activity that results in new knowledge will, in turn, be used to guide selection of alternatives in future tasks that involve decision making. Codified rules and routines would be relied on to support evaluation of alternatives and selection of action decisions. Choice of alternatives, and decision outcomes then provide the backdrop upon which sense making, or justification, of decision rationale occurs. Such decision rationale, and its associated sense making can then be codified for (re)use in other contexts, applied to future activities that draw on it to create new instances of knowledge.
