A water resources consulting firm has three water plant senior designers. Two of the designers have a master's degree in engineering and the other a bachelor's degree in engineering and a Ph.D. in waste management. They travel to potential and existing water resource sites and plants to define technical projects and survey sites. Currently, the firm has 20 projects per year and each senior designer can handle 6 projects per year. What is the current labor utilization of the senior designers? What do you recommend?
