The emergence of change or shift in the environment is ordinarily unpredictable and powerful for an existing business. Current capabilities and knowledge are quickly becoming obsolete in a changing era. Moreover, the stock of knowledge captured and stored easily causes an overload in organizational memory. These problems will hinder the further development or even the company's survival.
On the other hand, more studies still focus on knowledge acquisition and learning instead of discarding and unlearning. It could escalate the problem in such a fluctuating time. This paper introduces the concept of knowledge divestment from knowledge management (KM) processes in the view of organizational unlearning, which emphasizes the readiness to change and unlearn individual behavior and the strong position of key individuals such as CEOs. Also, organizational culture could be influenced or, at the same time, act as an intervention for unlearning. This research is based on secondary data, compares three key KM models in the House of Quality Framework, and chooses the Bukowitz and Williams KM Cycle as the benchmark. The case of Nokia is introduced to prove the work and value of knowledge divestment in Williams's model. Furthermore, it finds that divestment through unlearning could help the organization redirect its strategy and convert the ancient knowledge to a new valuable one via relearning within the organization or redeploying outside to improve utilization via other organization's learning. Under the unstable environment and the matter of knowledge value, it is more effective to divest knowledge in this way instead of simply giving them up.
