Question

What visual aid is most effective in auditing and why?

Answer 1

Audit results can be converted into statistical maps that will visually demonstrate the performance of a system or process against best practices.

Horizontal bar graphs are superior for visually communicating the same information. The bars can be easily ordered as a Pareto. The category labels would be in a simple column next to the vertical axis. The goal could be displayed simply as a subtle line. The graphs can be legibly packed into a compact space.

Radar charts are excellent when using them to compare supplier audit results, such as when evaluating/comparing audit results during a supplier selection process.

Some other visual aids are:

Time-series line graphs. These visual aids can be used to show financial metrics, such as revenue and cost of sales, over time. They can help stakeholders identify trends, like seasonality and rates of growth (or decline), that can be used to interrupt historical performance and project it into the future.

Bar graphs. Here, data is grouped into rectangular bars in lengths proportionate to the values they represent so data can be compared and contrasted. A company might use this type of infographic to show revenue by product line or geographic region to determine what (or who) is selling the most.

Pie charts. These circular models show parts of a whole, dividing data into slices like a pizza. They might be used in financial reporting to show the composition of a company’s operating expenses to use in budgeting or cost-cutting projects.

Effective visualizations avoid “chart junk.” That is, unnecessary elements — such as excessive use of color, icons or text — that detract from the value of the data presentation. Ideally, each infographic should present one or two ideas, simply and concisely. The information also should be timely and relevant. Too many infographics can become just as overwhelming to a reader as too much text.
