Corporate strategy attempts to define the domain of businesses the firm intends to operate. Consider three Japanese electronics firms: Sony competes in the global market for consumer electronics and entertainment but has not broadened its scope into home and kitchen appliances. Corporation focuses only on electronic audio and video products. Each firm has answered quite differently the question of what constitutes its business domain. Their divergent answers reflect their differing corporate strengths and weaknesses, as well as their differing assessments of the opportunities and threats produced by the global economic and political environments.
