Functional flow block diagram

About this block diagram

A functional flow block diagram is a multi-tier, time-sequenced, step-by-step flow of the functional flow of a system. It shows the work of a lawnmower and divides the work into main phases. These diagrams are useful in system engineering. They describe complex processes.

The diagram's top level shows four steps: prepare for the lawnmower, start it, cut the grass, and shut it off. This is a brief description of the functions that are used at the highest level to manage the lawnmower; using a block diagram makes it simple to follow the paper.

The first step, ‘prepare lawn mower’, is subdivided into other tasks as follows; This very detailed step of the functional flow block diagram shows that one has to look for the lawnmower, look for protective equipment, do an eye inspection, take the lawnmower to the lawn, and finally check for anything on the lawn.

Thus, the main advantage of the functional flow block diagram is that it makes it easy to convey the hierarchy and the interdependence of the steps. The diagram, in the first step's flow, shows users how much planning and direction they need.

Essentially, functional flow block diagrams provide the proper sequence for each activity to be performed to reduce the chance of developed errors or accidents.
