TECHNIQUES

1. Prepare complete examples of each output and input in the system. This can be prepared using a prototyping tool or some other media (e.g., pencil/paper, text editors, etc.).

2. Be sure to show actual data values on the screen for the user to visualize on the report or screen. Do not show entries such as "XXXXX," "ZZZZZ.ZZ" or "00000."

   Show variations of the examples. For example, show how data exceptions are handled, errors, messages, default values, overrides, etc. Also, consider how foreign languages will be accommodated (if applicable).

   Concentrate on developing the outputs first. This will then become the basis for the inputs.

   NOTE: Preparation of the illustrative examples may require participation of the user during this activity. Otherwise, the user will review the recommended examples as part of the final phase deliverables.

   For additional design tips for creating inputs and outputs that cross geographical borders, see: Creating Universal Systems.

3. Update the physical characteristics of the data elements in the IRM (DD's). For example, length, precision, scale, fill character, void state, justification, validation rules, etc.

4. Update the Descriptive Text for each Input and Output (ID/OD) with an explanation of how each is produced, including:

   • How headings and footers are produced (including pagination).

   • How the body is produced, including special processing rules.

TOOLS

During this activity, use the following types of tools:

1. Documentation Aid to record notes and develop narratives to describe the inputs and outputs.

2. Prototyping Tools such as a Graphical User Interface (GUI) development tool.

3. Screen Painting tools.

4. Text Editors to map out character based screens and printed reports.

5. Screen Capture tools to print examples.

6. Pencil and Paper for simple examples.

7. Repository to document inputs, outputs and data elements (ID, OD, and DD).
