Final answer:
It is true that strategy implementation is the most challenging phase in strategic-management due to the need for personal discipline, commitment, and proactive planning.
Step-by-step explanation:
Strategy implementation is often cited as the most difficult stage in the strategic-management process. Indeed, it is true that this phase requires personal discipline, commitment, and sacrifice. Unlike strategy formulation, which is more about analysis and decision-making, strategy implementation involves changing an organization's processes and culture, which demands commitment from individuals to alter their thinking and behaviors. Moreover, achieving strategic goals necessitates careful planning to ensure that the objectives set are attainable and appropriate to the given situation. It's a complex process that entails coordination among various stakeholders and the alignment of resources and actions with strategic goals. Thus the inherent challenges of strategy implementation frequently make it a strenuous phase for organizations.
