ANS:B - production schedule

Gantt charts are primarily used for streamlining the production schedule. A Gantt chart is a popular project management tool that visually represents the scheduling of tasks over time. It provides a graphical representation of a project's timeline, showing the start and finish dates of various project activities, as well as their dependencies and progress. Gantt charts are particularly useful for scheduling and coordinating tasks in manufacturing and production environments, where it is essential to plan and monitor the sequence of activities to ensure timely completion of projects and efficient resource utilization. While Gantt charts may indirectly impact aspects like inventory control and quality control by helping to manage production schedules effectively, their primary purpose is to facilitate project planning and scheduling.
