Consider a law firm with 15 lawyers and 3 paralegals. The firm is struggling to keep up with the high demand for its services, particularly during the busy litigation seasons. It has been observed that the lawyers spend a significant amount of their time on administrative tasks that could potentially be handled by paralegals. After a careful study of the work distribution within the firm, it was determined that 35% of the activities carried out by the lawyers are administrative in nature. Given that each lawyer works 50 hours a week, please determine: (a) How many additional paralegals should the firm hire to handle the administrative tasks currently performed by the lawyers? (b) If the lawyers' time spent on administrative tasks is redirected to billable legal work, by what percentage could the firm potentially increase its billable hours?

Tax Prep Advisers, Inc., has forecasted the following staffingrequirements for tax preparation associates over the next12 months. Management would like three alternative staffingplans to be developed. The company currently has 10 associates. No more than 10new hires can be accommodated in any month because oflimited training facilities. No backorders are allowed, andovertime cannot exceed 25 percent of regular-time capacityon any month. There is no cost for unused overtime capac-ity. Regular-time wages are $1,500 per month, and overtimewages are 150 percent of regular-time wages. Undertime ispaid at the same rate as regular time. The hiring cost is $2,500per person, and the layoff cost is $2.000 per person.a. Prepare a staffing plan utilizing a level workforce strategy,minimizing undertime. The plan may call for a one-timeadjustment of the workforce before month 1.b. Using a chase strategy, prepare a plan that is consistent withthe constraint on hiring and minimizes use of overtime.c.…
