Explain flow time and lateness in operation management?

Flow time in operation management refers to the total time taken for a unit of work to move through the entire production process, from start to finish. Lateness, on the other hand, measures the difference between the completion time of a task and its due date, indicating whether the task is completed ahead of schedule or late. Effective management of both flow time and lateness is crucial for optimizing production efficiency and meeting customer deadlines. Reducing flow time can help minimize lateness, leading to improved operational performance.
