What is HIPO Chart?
The chart displays the overall program structure. This tool is used during the program design or the initial planning phase.
There are several names for this chart. A hierarchy chart is also known as:
- Structure Chart
- Top-down chart
Structure charts because the chart displays the overall program structure. Top-down chart because the tool is used during top-down program development approach.
The Structure chart is high-level and only shows the organization of the program. The chart breaks the program into modules and sub-modules. It displays how the program modules are related to each other. It doesn’t go into implementation or processing details. This chart is prepared before writing the program code.
The Top-down chart is read from the top to the bottom and from the left to the right direction.
