The analysis tool that shows the flow of input data to processing and finally to output is the system

The analysis tool that shows the flow of input data to processing and finally to output is known as a "Data Flow Diagram" (DFD).

Here are the steps to create a Data Flow Diagram:

1. Identify and define the process: The first step in creating a DFD is to identify the process or system that you will be analyzing. This could be a software system, a business process, or any other type of system that involves data flow.

2. Identify the inputs and outputs: Next, you need to identify what data is input into the system and what data is output from the system.

3. Identify the data flows: After identifying the inputs and outputs, you need to determine how the data flows between them. This involves identifying the processes that the data goes through as it moves from input to output.

4. Draw the diagram: Once you have identified the processes, inputs, outputs, and data flows, you can start to draw your DFD. This typically involves drawing a box for each process, with arrows representing the data flows between them.

5. Review and refine: After drawing your initial DFD, you should review it to make sure it accurately represents the system you are analyzing. You may need to refine it by adding, removing, or changing processes, data flows, inputs, or outputs.

6. Finalize and use: Once you are satisfied with your DFD, you can finalize it and use it as a tool for understanding and improving the system you are analyzing.
