• 2. QWIK RATIO EXERCISE Directions: Step 1. Gather the Data Complete the data table, Page 1 of the exercise. Note: If you don’t have the data, provide a “best estimate” number. Step 2. Calculate the Ratios Using the value in the data table (Page 1), calculate the indicated rations in each of the 10 boxes on Page 2. For example, to calculate the first ratio, Maintenance Cost, % ERV, do the arithmetic in the box: Line #6 / Line #8 Score your result on a scale of 1-10 based on the scale shown for each ratio. <2.5% 3.0% >3.5% Points 10 5 1 Note: If you don’t have the data, even an estimate of the data, and can’t do the calculation from the data, then at least estimate (or guess) the ratio and score it 1-10 on the scale. You now should have a 1-10 score in each of the 10 boxes. Step 3. Plot the Radar Chart (“spider diagram”) Using the radial scale of 1–10 on the radial graph (page 3), plot each of the 10 box scores on its corresponding radial line. Connect the points. Color the diagram. INTERPRETATION This chart has been designed to plot industrial averages at about 5 points, and “world class” or “best of class” numbers about 10 on the chart. That means that to the degree that you are “world class” you will have lots of area under the curve, most ratios close to 10 (say 7 or better). To the degree that you have “opportunity” for improvement, your values will be low, and not much area under the curve (say 0–3); there will be lots of “white” space on the outside of the curve. See the example plot on Page 4. ©Marshall Institute, Inc. r1 1-800-637-0120 Instructions
