"Mr. X is the supervisor for a dry cement packaging company. His work crew iscomposed of unskilled workers who load large transport trucks with bags ofcement, gravel, and sand. The work is hard, and the employee turnover rate ishigh. Employees record their attendance on separate time cards. Mr. Xauthorizes payroll payments each week by signing the time cards and submittingthem to the payroll department. Payroll then prepares the paychecks and givesthem to Mr. X, who distributes them to his work crew." Is there an internal control issue or none? Justify your answer.

A company is setting up an assembly line to produce 90 units per hour. The table below identifies the work elements, times, and immediate predecessors. Work Element Time (Sec.) Immediate Predecessor(s) A 25 - B 18 A C 20 A D 5 B, C E 12 C F 8 E G 16 D, F H 12 G Use one of the heuristic decision rules described in Table below to balance the assembly line so that it will produce 90 units per hour. Clearly state the decision rule you use and complete the below table using the selected rule. Decision Rule Logic Longest work element Picking the candidate with the longest time to complete is an effort to fit in the most difficult elements first, leaving the ones with short times to “fill out” the station. Shortest work element This rule is the opposite of the longest work element rule because it gives preference in workstation assignments to those work elements that are quicker. It can be tried…
Personnel Planning; TDABC Recent competitive pressures have caused National InsuranceCompany to examine policies regarding personnel planning. As a start, the company has decided toexperiment with and develop a time-driven ABC model for its claims processing center.A study of this support center indicates the following three primary activities: remote processingof customer claims, 0.5 hour; onsite processing of customer claims, 1.0 hour; and updating/maintaining customer records, 0.2 hour. Onsite processing is required for larger claims, while remote processing is done for smaller claims. (For onsite processing, assume—for simplicity—that the claimsprocessors use their own automobiles.) All claims will require that the customers’ records be updated.The claims processing center currently employs three full-time employees. Total annual cost ofthe center (salaries, depreciation, utilities, etc.) is estimated at $255,000. The net amount of availablepersonnel time per year for this…
2. Jamila wants to set up a manufacturing unit, so she meets with Rashid, a humanresource manager at her company. Rashid explains that in order to decide on thehuman resource needs for the unit, they should conduct a workflow analysis. Shesuggests they start by defining the outputs of the process. To do this, what shouldJamila define?A) the processes that will be involved in manufacturingB) the number of people required for productionC) the type of products that will need to be manufacturedD) the special equipment, facilities, and systems needed for productionE) the data and information needed by the work unit
