Final answer:
Statement B) Creating value for customers is an important part of planning and implementing strategy is true. Customer value is a key factor in strategy but not the only one, and it is not shown on a balance sheet. Additionally, increased costs do not automatically lead to lost customer value, especially if associated with perceived value.
Step-by-step explanation:
The correct answer for the statement about customer value is B) Creating value for customers is an important part of planning and implementing strategy. Customer value is not a tangible asset that is reported on a corporation's balance sheet, which makes option A incorrect. While customer value is important, option C is not true as it is not the only focus for managers when formulating strategies. Managers must also look at other aspects such as competition, company capabilities, and financial resources. Lastly, customer value may not necessarily be lost with an increase in costs of the product. This is incorrect because if the perceived value or the quality of the product increases with the cost, customers may still find value in the product, rendering option D incorrect. Strategy implementation focused on customer value requires understanding the needs and preferences of customers and aligning products or services accordingly to meet or exceed them.
