Assimilation, Integration, Separation and Deculturation.
Option (a) is incorrect because, in Integration, both entities aim to preserve most of their identity, cultural characteristics, and organizational practices. This would be an ideal setting for the new entity, if both cultures can be managed well. to achieve harmony, both parties must be willing to substitute or abandon existing values and adopt new ones that may emerge over time.
Option (b) is incorrect because in separation each entity agrees and attempts to maintain all of its cultural elements, remain autonomous and independent of the other entity. This strategy requires the commitment from the acquiring company not to interfere and impose values on the acquired.
Option (d) is incorrect because, Deculturation, also called Marginalization, involves the loss of cultural identity and the refusal to adopt a new one by the acquiree. The acquired employees can no longer identify with their old organizational culture, and resist being assimilated by the acquirer.
