Used in program design, this tool presents a graphic presentation of the detailed sequence of steps needed to solve a programming problem.

The tool you're referring to is called a "Flowchart". A flowchart is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. This diagrammatic representation illustrates a solution model to a given problem. Flowcharts are used in analyzing, designing, documenting or managing a process or program in various fields.

Here's a step-by-step guide on how to create a flowchart:

1. Identify the Process or Task to be Flowcharted: This is the starting point for your flowchart. It could be a problem that needs a solution, or a process within your organization that you want to visualize.

2. Gather Information on the Process: This includes all the steps involved in the process, the decisions to be made, and the outcomes of those decisions.

3. Start to Plot the Flowchart: Begin with the start/end symbol, which is represented by an oval shape.

4. Add Steps and Decision Points: Use rectangles for instructions or actions, and diamonds for decision points. Arrows are used to guide the flow from one step or decision to the next.

5. Review and Test the Flowchart: Once you've plotted out your flowchart, review it to make sure it accurately represents the process. You can also test it by following the steps and decisions to see if it leads to the correct outcomes.

6. Finalize the Flowchart: Once you're satisfied with your flowchart, you can finalize it and share it with others.

Remember, the key to a good flowchart is clarity: it should be easy to understand and follow.
