People respond to clear goals and expectations.

In general, for people to be "leaders" within an organization, they need to CLEARLY understand the goals and objectives of the parent organization.

Parent goals should be defined using Key Performance Indicators (KPI)
metrics used to periodically track and evaluate the performance of a business or organization toward the achievement of specific goals. They are also used to gauge the overall performance of the company against other comparable companies within the industry.

Management by Objectives (MBO):
Technique suggested by Drucker in 1952 that links individual smaller goals to the larger organizational goals.
Tasks are then added to support the smaller goals and employees are evaluated and rewarded monthly, quarterly or annually. In theory, this technique could be used on a weekly basis.

Objectives by Key Results (OKR): https://corporatefinanceinstitute.com/resources/management/objectives-and-key-results-okr/
Objectives are stated. Expected results are clearly defined. Initiatives are created to achieve those results.
Objectives still need to align with the parent organization objectives, but contrary to MBO where the "smaller" objectives are set by managers (within a department), objectives within the OKR method can be set by the individual (still in support of parent objectives).
