Example of top down:

Company Management Structure: A CEO creates a strategic plan for the company and delegates tasks to department managers, who in turn delegate to their subordinates.How do you use top-down approach?

The top-down approach to project management means that you start with the final deliverable (project goal) and break it down into smaller, more manageable tasks. These tasks can be further broken down into subtasks — great details — and then assigned to individual teams and/or team members within that team.

Bottom-up processing happens when someone tries to understand language by looking at individual meanings or grammatical characteristics of the most basic units of the text, (e.g. sounds for a listening or words for a reading), and moves from these to trying to understand the whole text.
