Process engineers are responsible for designing, implementing, controlling, and optimizing industrial processes, especially continuous ones such as the production of petrochemicals1. One of the decisions that process engineers would most likely make is the routing sequence, which is the order of operations or activities that are performed on a product or material as it moves through the production process2. The routing sequence affects the process performance, efficiency, quality, and cost, and it requires careful planning and analysis by the process engineers. Option A is not correct, because lead times are the time intervals between the initiation and completion of a process or a project3. Lead times are influenced by many factors, such as demand, capacity, inventory, scheduling, and supply chain management, and they are not solely determined by the process engineers. Option B is not correct, because production capacity is the maximum amount of output that a process or a system can produce within a given period of time4. Production capacity depends on the availability and utilization of resources, such as materials, labor, equipment, and facilities, and it is not only decided by the process engineers. Option C is not correct, because product reliability is the probability that a product will perform its intended function without failure for a specified period of time under specified conditions5. Product reliability is affected by many aspects, such as product design, quality control, testing, maintenance, and customer feedback, and it is not the sole responsibility of the process engineers.
