The person most responsible for all aspects of strategic management is typically the Chief Executive Officer (CEO) or the top-level executive of an organization.

The CEO is accountable for:

• Formulating strategy: Defining the mission, vision, and strategic goals of the organization.
• Implementing strategy: Ensuring that the strategy is effectively translated into action throughout the organization.
• Evaluating and controlling strategy: Monitoring performance, identifying deviations from the strategic plan, and taking corrective action.

While the CEO holds the ultimate responsibility, strategic management is often a collaborative effort involving other key members of the executive team, such as:

• Chief Operating Officer (COO)
• Chief Financial Officer (CFO)
• Other senior vice presidents or directors

Additionally, the board of directors plays a crucial role in overseeing and approving the organization's strategy.

Ultimately, the CEO is the person most responsible for the success or failure of the organization's strategic management efforts.
