This is a Pareto Chart - If you address the tallest column (always on the left of the chart) you will make the most improvement with the least amount of effort. pg. 166 - "The Official CompTIA Project+ Guide"
Remember the 80/20 rule: 80% of the problems come from 20% of the causes. We want to eliminate that 20% that causes 80% of our problems. If we look where the cumulative % bar passes 80% and draw a line straight down, that is the cause that will give us the greatest benefit by fixing. It is the 20%. We should focus on that first and then we can look at more common issues.
Aside from the fact that B has the highest impact. It also mentioned that you were tasked with refurbishing the desktops. If your boss tells you to refurbish a DESKTOP and he comes back and all youve done is replace the peripherals (Webcams, Keyboards, Headphones, Printers) say goodbye to your job.
Don't get tripped up by the histogram, it's a ratio of the CUMULATIVE percentages vs overall defects. The eighty-twenty rule. What least amount of work or resource drain can we do or use, to produce the greatest impact. It's a ratio.
Via Google:
A Pareto chart is a bar graph. The lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right. In this way the chart visually depicts which situations are more significant.
