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?arrow_forwardGalaxy Candy Company manufactures two popular candy bars, the Eclipse bar and the Nova bar.

- Chris has three different workstations: one for drip coffee, one for espresso drinks, and one to prepare food. During the morning rush, Chris has 5 people working: one person at the drip coffee station, two at the espresso station, and two at the food prep station. These employees are not cross-trained, and thus must stay at their station. On average, it takes the person at the drip coffee station 1 minute to make the coffee. On average, it takes one person working at the espresso station 3 minutes to make one espresso drink. On average, it takes one person working at the food station 4.5 minutes to prepare the food for one customer.

Due to increased levels of competition, this company is now increasingly finding it difficult to compete – especially as the larger companies seem to be a little more innovative, agile and responsive to client requirements. Management have noticed that staff, especially the highly skilled ones, are now leaving the company to seek work elsewhere (in these larger companies). This has meant appointing new staff and undertaking a considerable amount of re-training to replace those that have left the company. Apart from impacting on core business operations, ABC Solutions has started witnessing a drop in its profit margin. Given this position, senior management at ABC Solutions have decided to implement a performance measurement tool (PMT) that would allow them to align the strategic, management and operational requirements of the business. They are therefore considering the adoption of the…arrow_forwardDon't used Chat gptarrow_forward
