What is top-bottom approach in project planning?

The top-bottom approach in project planning involves senior management setting the overall goals and objectives, which are then communicated down to lower levels of the organization for execution. This method emphasizes alignment with the company's strategic vision and ensures that all team members understand how their tasks contribute to broader objectives. While it can lead to efficient decision-making and clear direction, it may also limit input from lower-level employees, potentially overlooking valuable insights from those directly involved in the work.
