By tapping into the vast reservoir of creative intellect and expertise within any type of organization, anyone in the organization can share their knowledge. People within or outside of an organization can similarly search for the knowledge of others, creating the potential for perpetual innovation and continual performance improvement. Nadler and Tushman (1998) further suggest, "Successful firms will learn and act at a faster rate than the competition. The ability of an enterprise to perform certain types of behaviors, resulting from shared learning, appears to be one of the few remaining points of leverage for enterprises that seek to fundamentally better their competitive positions". They further explain that organizations that believe that knowledge, insight and ideas are found inside the organization rather than outside are doomed to a "death spiral". Usually, this is because they lose their customer focus, speed deteriorates, and they "become less capable of effectively innovating in ways that contribute to marketplace success". They contend that organizational learning is the ability to gain insight from experience. They examine their strategies and processes in relation to what is learned. "Effective learning occurs when people reflect on the consequences of their actions and gain insight, such as a richer and more accurate understanding of the key factors in their environment". "Sharing information among organizational groups is critical in facilitating reflection and action. Effective learning systems surface differing perspectives in order to better interpret experience and spark innovation".
