Which of the following is not a step in task planning?

Managing waste is not typically considered a step in the task planning process. Task planning primarily focuses on how to efficiently organize a project or set of activities to ensure successful completion. This includes creating a timeline to outline when tasks will occur, setting deadlines to establish a timeframe for task completion, and assigning specific tasks to team members to ensure accountability and clear distribution of responsibilities.

While waste management is certainly important in many projects, especially in terms of efficiency and resource management, it is more of a broader operational concern rather than a direct step in the planning phase itself. The other options—creating a timeline, setting deadlines, and assigning tasks—are integral parts of planning as they help define the scope, timing, and responsibilities involved in a project.
