QUESTION 2
VF is a small accounting firm supporting wealthy individuals in their preparation of annual income tax statements. Every December, VF sends out a short survey to their customers, asking for the information required for preparing the tax statements. Based on 24 years of experience, VF categorizes their cases into the following groups:
• Group 1 (new customers, easy): 25 percent of cases
• Group 2 (new customers, complex): 20 percent of cases
• Group 3 (repeat customers, easy): 30 percent of cases
• Group 4 (repeat customers, complex): 25 percent of cases
Here, “easy” versus “complex” refers to the complexity of the customer’s earning situation. In order to prepare the income tax statement, VF needs to complete the following set of activities. Processing times (and even which activities need to be carried out) depend on which group a tax statement falls into. All of the following processing times are expressed in minutes per income tax statement.

The activities are carried out by the following three persons:
• Administrative support person: filing and writing.
• Senior accountant (who is also the owner): initial meeting, review by senior accountant.
• Junior accountant: preparation.
Assume that all three persons work eight hours per day and 22 days a month. For the following questions, assume the product mix as described above. Assume that there are 50 income tax statements arriving each month.
g. Due to the recent regulation change, the writing stage now takes 30 minutes longer for all cases, what is the new implied utilization rate for the administrative support person? Round your answer to the nearest whole number and ignore the percentage sign. For example, if your answer is 0.45 or 45%, fill in 45; if your answer is 0.76 or 76%, fill in 76.
Your answer is .
The characterization of cases of firm are as given below:
• Group 1 (new customers, easy): 25 percent of cases
• Group 2 (new customers, complex): 20 percent of cases
• Group 3 (repeat customers, easy): 30 percent of cases
• Group 4 (repeat customers, complex): 25 percent of cases
Now,
Since, the writing time has increased by 30 minutes in each case,
Hence new writing time would be -
Group 1 - 50+30 = 80 minutes
Group 2 - 80+30 = 110 minutes
Group 3 - 60+30 = 90 minutes
Group 4 - 60+30 = 90 minutes
Table for total work load of three resources -
Resource | Minutes per month | 1 | 2 | 3 | 4 | Total work load | Implied Utilization |
Administration | 10560 | 1250 | 1500 | 1650 | 1625 | 6025 | 6025/10560 =0.5705 = 57% |
Senior | 10560 | 625 | 1500 | 75 | 375 | 2575 | 2575/10560 = 0.2438 = 24% |
Junior | 10560 | 1500 | 3000 | 2250 | 2500 | 9250 | 9250/10560 = 0.8759 = 88% |
Calculations are as follows :
Administration = % of statements for the group x Total number of income tax statements x (Filing + Review writing)
Administration 1 = (0.25 x 50) x (20+80) = 1250
Administration 2 = (0.2 x 50) x (40+110) = 1500
Administration 3 = (0.3 x 50) x (20+90) = 1650
Administration 4 = (0.25 x 50) x (40 + 90) = 1625
Senior = % of statements for the group x Total number of income tax statements x ( Initial + Senior Accountant review)
Senior 1 = (0.25 x 50) x (30+20) = 625
Senior 2 = (0.2 x 50) x (90+60) = 1500
Senior 3 = (0.3 x 50) x (0+5) = 75
Senior 4 = (0.25 x 50) x (0+30) = 375
Junior = % of statements for the group x Total number of income tax statements x Meeting Preparation
Junior 1 = (0.25 x 50) x 120 = 1500
Junior 2 = (0.2 x 50) x 300 = 3000
Junior 3 = (0.3 x 50) x 150= 2250
Junior 4 = (0.25 x 50) x 200 = 2500
Hence,
The new implied utilization are -
Administration = 57%
Senior = 24%
Junior = 88%
