Key Differences Between Strategic, Tactical, and Operational Plans are:

Strategic Plans:

Time Horizon: Typically 3–5 years

Scope: Broadest; focus on the entire organization

Complexity: The most complex and general, because of potentially covering different industries and business (for groups of companies)

Impact: Have the potential to dramatically impact, both positively and negatively, the survival and success of the organization

Interdependence: High; must take into account the resources and capabilities of the entire organization and its external environments. 

Tactical Plans: 

Time Horizon: Often focused on 1–2 years in the future

Scope: Typically focused on a strategic business unit

Complexity: Complex but more specific, with a more limited domain of application

Impact: Affect specific business units, but the effect on the entire organization is measured

Interdependence: Moderate; must take into account the resources and capabilities of several units within a business

Operational Plans:

Time Horizon: Usually focused on the next 12 months or less

Scope: Narrowest; usually centered on departments or smaller organizational units

Complexity: The least complex, because of usually focusing on small, homogenous units

Impact: Impact is usually restricted to a specific

department or organization unit

Interdependence: Low; the plans may be linked to higher-level tactical and strategic plans but are less interdependent

The correct answer is Choice D.
