Creating visual aids and models requires a systematic process that starts with planning: defining the scope, objectives, and requirements of the visual aid or model; identifying the sources, inputs, and outputs; choosing the type, format, and medium; and allocating the time, resources, and tools. This is followed by designing: sketching or outlining the structure, layout, and elements of the visual aid or model; applying principles of clarity, simplicity, consistency, and relevance; and using colors, shapes, symbols, labels, and legends. Then comes developing: building or refining the visual aid or model; utilizing appropriate tools; testing and validating; incorporating changes as needed. Finally, reviewing: evaluating the quality and accuracy of the visual aid or model; seeking feedback from stakeholders or experts; revising or modifying it as needed. By following this process you can create visual aids that meet your business analysis needs and standards.
