Which of following statements is/are true concerning strategic positioning?

		Once a firm has chosen a position, it is unwise to change it, even though the company or business environment might change.
		If a firm does decide to compete on more than one strategic position, it must carefully execute both strategies to be successful.
		Since the business environment is always changing, rather than stick constantly with one strategic position, firms should pay close attention during times of change, and adjust their strategies accordingly.
		A firm following both competitive strategies is likely to succeed only if it achieves one of the strategies very well.
