Learn how to use IPO Chart, a tool for computer programming and systems analysis, to describe the input, process, and output of a system or process. See an example of an IPO chart for computing the area of a rectangle and how to use it with Raptor Flowchart, a software for creating flowcharts.
Jul 19, 2023 · An IPO diagram helps you identify all the factors that influence a process and all the process’s outcomes, and it gives you a structured approach to analyzing and improving the system. The IPO diagram consists of three columns listing inputs on the left, describing the process in the middle, and then tracking the outputs on the right.

A comprehensive introduction to Input Process Output tables. Learn how to effectively model the important processing going on in your system. One of the first things we need to do in software development is understand the problem. We can't begin to plan the most effective solution until we properly understand what it is we are trying to solve. Inpu...
There are several different methods for displaying IPO tables. Some people prefer to list the items vertically instead of horizontally for instance. However you choose to display them is fine, the underlying principle of what they convey will still be the same. The layout described here is one which I find particularly easy to read. This layout mak...
When thinking about software development we can divide processes into two types. Those which are part of the problem, and those which are part of the implementation of the solution. Let's look at an example to illustrate what is meant by this. If we are going to make a simple calculator then the processes of addition, subtraction, multiplication an...
Any process may be explored through an IPO table but if we say that it's purpose is to help us better understand and define the problem then this gives us guidance as to which processes would be better to model. Ideally we want to model processes representing the problem. Processes which are part of implementing the solution are generally better ex...
A common mistake when creating IPO tables is to specify actions as either your Inputs or Outputs. For example an input may be listed as player wins game. This is incorrect as it is not an input but an event that occurs which triggers the processing. In an IPO we are not concerned with what triggers the processing (that will be looked at in other di...
So how do Input Process Output tables fit into the big picture of software design and development? IPO tables are a valuable tool to help you define and understand the problem. This may be one for which a computerised solution is to be created. Alternatively it may be an existing system which is to be replaced or improved. IPO tables will help you ...
Pick a sport and create a set of IPO tables that would be required if you were going to develop a piece of software to manage scoring for a game.
- Layout of the Chart: You can create a simple table, with three boxes in a single row, for your IPO chart. Leave room to label the boxes with "Input," "Process" and "Output".
- Input: In your "input" box, describe whatever data you want to process. To give a simple example, you could write "Number of hours worked". A more complex example might be, "Unique visitors to our website in any given month".
- Process: In the "Process" box, describe what you intend to do with the data. For example, with "Number of hours worked," you might describe how you process that data as, "Multiply hours worked by wages per hour".
- Output: In the "Output" box, describe the output you want for the data you processed. This is the practical result you can use. For the "hours worked" data, processing it by multiplying times hourly wages results in an output of total money spent on wages.

Learn how to use the input–process–output (IPO) model to describe the structure of a computer program or any other process. See examples of pseudocode, flowchart and code for converting Fahrenheit to Celsius temperatures.
The input–process–output (IPO) model, or input-process-output pattern, is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. Many introductory programming and systems analysis texts introduce this as the most basic structure for describing a ...
