Effective ways of displaying information

2.2.2 A second diagram

This first representation can be developed in the way shown in Figure 11.

Figure 11
Figure 11: Inputs, transformation, outputs

Figure 11 includes a general representation of the process that transforms the inputs into outputs. In the example, the transformation is the movement of the passengers, the customers, from their home railway stations to the stations close to their work. The diagram can help your thinking in two ways:

  • It emphasises the need for a transforming process. Something must be done with the inputs in order to achieve the outputs.

  • The transformation process is the reason for the existence of the organisation. It is the value that the organisation adds to the inputs.

You can apply an input-output diagram to an organisation or to a part of an organisation. You can apply it to your own work or to your activities outside work.

When you identify the inputs and the outputs, identify those ones that are sufficient for your purposes. Sometimes, it will be appropriate to identify a relatively long list of both. At other times, it will be sufficient to identify just the major inputs and outputs.
