2. Given the following narrative description of a payroll process for wage workers, which is currently a manual process, draw a context diagram and a level-0 DFD for the activities with several processes described. State any assumptions if you have any. Roger Petersen is a longtime warehouse supervisor of 45 wage workers at a medium- sized export facilitation company that provides services to approximately 400 companies around the state of Wisconsin. Every Monday, Christine Moran from Accounting sends Roger new prenumbered, labeled time cards. Roger places the time cards in the lounge area where employees check in and out on the cards at the beginning and end of each shift. Roger’s office is a glassed-in area at the end of the employee lounge and he makes a point of being in his office to observe the arrival and departure of employees. On Friday, Roger reviews the hours recorded by each employee, approves any overtime, and prepares a payroll summary sheet showing the number of time cards and the total number of hours worked by all employees that week. Roger forwards the time cards and summary sheet to Accounting where Christine Moran reviews Roger’s math (he rarely makes a mistake) and prepares a payroll input delivery form for the Computer Service Center to process payroll. The service center prepares weekly payroll checks, computes gross pay, calculates various payroll taxes, determines employee deductions, calculates net pay, updates earnings records, and prepares the weekly payroll journal for all warehouse workers. When Christine receives the information back she compares the paychecks and journal to the information on the payroll input delivery form and makes the necessary payroll entries into the company’s computerized general ledger package. Christine sends the prenumbered checks, which are also watermarked and Void after 90 days to Roger for distribution to employees the following Friday. If any employees are sick or on vacation Roger holds the checks for them until they return, but no longer than 2 weeks. At the end of two weeks, the checks are forwarded to Christine Moran, who also reconciles the payroll account at the end of each month.
