Problem solvers often have multiple operators available to them but must select just one to apply. We present three experiments that demonstrate that solvers use at least two sources of information to make operator selections in the building sticks task (BST): information from their past history of using the operators and information from the current context of the problem. Specifically, problem solvers are more likely to use an operator the more successful it has been in the past and the closer it takes the current state to the goal state. These two effects, respectively, represent the learning and performance processes that influence solvers ’ operator selections. A computational model of BST problem solving, developed within the ACT-R theory (Anderson, 1993), provides the unifying framework in which both types of processes can be integrated to predict solvers ’ selection tendencies. � 1996 Academic Press, Inc. Most problems can be approached in multiple ways but solved by only a few. Problem solving can be viewed, then, as finding one of the few paths that leads from a problem’s initial state to its goal state through some space of possible intermediate states (Newell & Simon, 1972). In this framework,

In the knowledge-based theory of the firm, the ability to create new knowledge is seen as the most important source of a firm’s sustainable competitive advantage. Knowledge creation is explained through concepts of dynamic routines and dynamic capabilities. In the evolutionary framework dynamic routines correspond to search routines and in the dynamic capability literature dynamic capabilities are relatively simple rules that organizations follow. These different approaches identify accumulated knowledge as the main explanation factor for innovation. The discussion about the characteristics of creativity questions these different assumptions and suggests that creativity and its related routines need to be considered in order to understand and favor the knowledge creation and innovation process.
