Figure 2 uses a scatter diagram to display the importance ratings of 24 job tasks identified from the job analysis (X-axis) with the usefulness rating from the internet survey (Y-axis). Twenty-three of the job tasks fell along the important lower left to upper right diagonal, providing impressive support for the effectiveness of the certification. MCSEs rated the certification as most useful for those job areas that were most important. They did not rate the certification as useful for everything that they did-unimportant job areas generated lower usefulness ratings for the certification. The one job task that clearly did not fall along the lower-left to upper-right diagonal warranted investigation for increased coverage as part of the certification process.
