The way in which we process and therefore understand written and spoken texts is often described as either top-down or bottom-up. In our first language, we probably make use primarily of top-down processing. Our previous experience of watching TV news gives us some knowledge and expectations from which to make predictions about the likely content, as well as the style of language that will likely be used by presenters and journalists.

Bottom-up processing is an explanation for perception that involves starting with an incoming stimulus and working upwards until a representation of the object is formed in our minds. This process suggests that our perceptual experience is based entirely on the sensory stimuli that we piece together using only data that is available from our senses. In order to make sense of the world, we must take in energy from the environment and convert it to neural signals, a process known as sensation.
Generally speaking, there are two approaches to understanding the process of perception. These are the top-down processing and the bottom-up processing. What differentiates one from the other?
Top-down and bottom-up approaches are methods used to analyze and choose securities. However, the terms also appear in many other areas of business, finance, investing, and economics. Generally, each can be quite simple.
One of the things that makes project management so interesting is that no one can ever say that they have all the answers. Project management approaches and strategies are constantly being evaluated, revised and improved, and successful project managers make it a priority to stay informed about the latest developments in their field. In recent years, the world of project management has been the scene of a growing debate over two fundamentally different approaches to defining and assigning project tasks: the top-down approach vs.

Top-down and bottom-up are both strategies of information processing and knowledge ordering, used in a variety of fields including software, humanistic and scientific theories see systemicsand management and organization. In practice, they can be seen as a style of thinking, teaching, or leadership. A top-down approach also known as stepwise design and in some cases used as a synonym of decomposition is essentially the breaking down of a system to gain insight into its compositional sub-systems in a reverse engineering fashion.
