In this tutorial, we will learn about IPO Chart. IPO stands for Input, Process, and Output.
IPO chart is a handy tool to approach problem-solving before designing the flowchart. IPO chart is a table with three columns.
IPO chart is a breakout to determine the inputs, processing, and outputs of the flowchart.
The Input column specifies the input to the flowchart entered in the Input dialog, input file.
Process columns contain the processing items or computations and calculations done in the flowchart.
The Output column specifies the output of the flowchart displayed in the Master Console window, output file.
For example, an IPO chart to compute the area of rectangle flowchart would be:
The input column is the input for the flowchart. We need the length and the width of the rectangle to compute the area. So, the input for the flowchart is the length and the width of the rectangle.
Process column contains the processing to the input to provide valuable information to the user in the form of the output. To compute the rectangle area we need to multiply the length and the width of the rectangle.
area= length * width
The output provides the output to the user. The mandatory output is the area of the rectangle. To enhance the user experience, we can replay the input variables to the output screen as well.
