4. Provide scatter diagram showing the relationship between IT Budget and Organization’s Revenue . Create a trend line. Provide labels for X and Y axis. Title the chart. Display revenues in millions. Display IT budget in thousands. (10 points). Use the following data: Fiscal Year IT Budget (in $) Use of EHR Organization’s Revenue (in $) 2009 200,000 20,000 130,000,000 2010 230,000 22,000 133,000,000 2011 275,000 23,000 137,000,000 2012 300,000 27,000 139,000,000 2013 320,000 30,000 140,000,000 5.

Consider the following ratings for the need for information and indicate which piece of information should be collected regularly and made available through the computer to decision makers, which other pieces of information should be planned for and finally which pieces of information does not require data collection. Show how your conclusions are derived from ranges and averages in the data, using the median to separate high and low values.

Impact of quality should be collected. Impact of cost doesn’t need data. 8. Assume that cost is 2 times more important than reputation and reputation is 3 times more important than compatibility with existing systems, and compatibility is 5 times more than ease of use , what is the relative importance of all 4 attributes. Answer the question calculating weights. (10 points) Ease of use=x compatibility=5x reputation=15x cost=30x Total=x+5x+15x+30x=51x weights will be 1/51,5/51,15/51, 30/51 respectively. weight for ease of use=1/51=0.02 weight for compatiability=5/51=0.1 weight for reputation=15/51=0.3 weight for cost=30/51=0.6 9. A purchasing committee has rated 4 systems on 4 criteria as follows: Compatibility with existing systems Ease of use Cost Reputation System A 60 10 50 80 System B 50 70 0 60 System C 80 60 90 40 Standardize attribute ratings (10 points) Compatibility with existing systems Ease of use Cost Reputation This study source was downloaded by 100000809230712 from CourseHero.com on 02-28-2024 09:36:29 GMT -06:00 https://www.coursehero.com/file/70203906/HAP-360-Midterm-2020doc/
