In process management, block diagrams are a visual vocabulary for describing activities within a complex system where cubes are black boxes which represent logical or mathematical operations which exist in sequence from left to right and top to bottom, but not the physical entities, such as processors or relays, that execute those operations. It is likely to make such cube diagrams and implement their functionality with technical programmable logic controller (PLC) programming languages.

In biology there is an increasing use of technology fundamentals, techniques of research and methods of diagramming. There is some correlation between the block structure and what is named Systems Biology Graphical Notation. Since it is there's use created in systems economics of the cube diagram technique exploited by controller engineering in which the latter itself is a program of control theory.

A block diagram is a type of a method where the principal components or functions are represented by cubes joined by lines that show the relationships of the blocks. They are heavily used in technology in hardware design, electronic design, software design, and process flow diagrams.

In electrical engineering, a layout may often start as a very significant level block diagram, getting increasingly more detailed block diagrams as the design progresses, eventually finishing in block diagrams comprehensive enough that every individual block is easily executed (at which point the block diagram will be also a schematic diagram). This is known as top down layout. [4] Geometric shapes are frequently used in the diagram to aid interpretation and describe meaning of this procedure or model. The geometric shapes are connected by lines to indicate institution and direction/order of traversal. Each engineering discipline has their own meaning for each shape. Block diagrams are used in each discipline of technology. They're also a valuable source of theory building and educationally valuable in non-engineering areas.

Block diagrams are generally used for higher level, less detailed descriptions which are intended to clarify overall concepts without concern for the particulars of implementation. Compare this with the schematic diagrams and layout diagrams used in electric engineering, which show the implementation details of electrical elements and physical construction.

For example, a block diagram of a radio is not anticipated to show each and every connection and dial and change, but the design diagram is. The design of a radio doesn't demonstrate the diameter of every connection from the circuit board, but the layout diagram will not.

To make an analogy to the map manufacturing planet, a block structure is very similar to a highway map of an entire nation. The major towns (serves ) are listed but the minor county roads and city streets are not. When troubleshooting, this elevated degree map is helpful in narrowing down and isolating in which a problem or malfunction is.

An illustration of that is the function block diagram, one of five programming languages described in section 3 of the IEC 61131 (see IEC 61131-3) benchmark that's highly formalized (see proper system), with strict rules for the diagrams should be built. Directed lines are utilised to connect input factors to block inputs, and prevent presses to output variables and inputs from other cubes.

Block diagrams rely on the principle of the black box in which the contents are concealed from view to avoid being distracted by the details because the details are not known. We understand what goes in, we know what happens, but we can not see how the box does its work.
