Step-by-step explanation:
In the planning process, once a planner completes environmental scanning, the step that should be applied by planners is developing strategies.
Environmental scanning involves gathering information about the internal and external factors that can affect the organization's plans. Once this information is collected, planners need to develop strategies to achieve the objectives set for the organization. Strategies are the actions and approaches that will be used to achieve these goals.
After strategies are developed, they can be implemented and plans can be put into action. Finally, performance needs to be evaluated to assess the effectiveness of the plans and make any necessary adjustments.
