Production Planning and Control Viva Questions and Answers

Q: What is Production Planning and Control (PPC)?

A: Production Planning and Control (PPC) is the process of planning, scheduling, controlling, and coordinating the manufacturing processes to ensure that products are produced efficiently, on time, and to the desired quality standards.

Q: What are the objectives of Production Planning and Control?

A: The objectives of Production Planning and Control are to ensure that the manufacturing processes are carried out efficiently, minimize production costs, optimize the use of resources, maintain quality standards, meet delivery deadlines, and improve customer satisfaction.

Q: What is the difference between Production Planning and Production Control?

A: Production planning involves the preparation of a detailed plan for production, which includes the determination of the required resources, scheduling of activities, and the establishment of production targets. Production control, on the other hand, involves the monitoring and control of the production process to ensure that it conforms to the plan and achieves the production targets.

Q: What are the different types of Production Planning?

A: The different types of production planning include long-term planning, medium-term planning, and short-term planning. Long-term planning involves planning for the production of products over a period of several years, while medium-term planning involves planning for the production of products over a period of several months to a year. Short-term planning involves planning for the production of products over a period of a few weeks or less.

Q: What are the different techniques used in Production Planning and Control?

A: The different techniques used in Production Planning and Control include forecasting, capacity planning, production scheduling, material requirement planning (MRP), just-in-time (JIT) manufacturing, and total quality management (TQM).

Q: What is Material Requirement Planning (MRP)?

A: Material Requirement Planning (MRP) is a technique used in Production Planning and Control to ensure that the required materials are available for production at the right time, in the right quantity, and at the right cost. It involves the use of computer-based systems to generate a detailed plan for the purchase and use of materials in production.

Q: What is Just-in-Time (JIT) Manufacturing?

A: Just-in-Time (JIT) Manufacturing is a technique used in Production Planning and Control to minimize inventory levels and reduce waste by producing goods only when they are needed, and in the quantity required. JIT manufacturing involves close coordination between suppliers and manufacturers to ensure that materials and components are delivered just in time for production.

Q: What is Total Quality Management (TQM)?

A: Total Quality Management (TQM) is a management philosophy that emphasizes continuous improvement in all aspects of an organization's operations. In the context of Production Planning and Control, TQM involves a focus on quality at every stage of the production process, from the design and development of products to their manufacture and delivery.

Q: What are the benefits of Production Planning and Control?

A: The benefits of Production Planning and Control include improved efficiency, reduced costs, better quality control, improved customer satisfaction, increased productivity, and better utilization of resources.

Q: What is Production Planning and Control?

A: Production Planning and Control is the process of planning, scheduling, and controlling the production process to ensure that products are manufactured efficiently and meet customer requirements.

Q: What are the objectives of Production Planning and Control?

A: The objectives of Production Planning and Control include optimizing the use of resources, minimizing costs, meeting customer demand, maintaining quality standards, and ensuring timely delivery of products.

Q: What is the difference between production planning and production control?

A: Production planning involves the preparation of production schedules, resource planning, and forecasting demand. Production control involves the actual implementation of the production plan, tracking progress, and making adjustments as necessary.

Q: What are the different types of production systems?

A: The different types of production systems include job production, batch production, mass production, and continuous production.

Q: What is a bill of materials (BOM)?

A: A bill of materials (BOM) is a document that lists all the components, parts, and raw materials required to produce a product.

Q: What is a production schedule?

A: A production schedule is a document that outlines the production plan and specifies the start and end dates for each operation and the resources required for each operation.

Q: What is a production capacity?

A: Production capacity is the maximum amount of products that a manufacturing facility can produce in a given period of time, under normal operating conditions.

Q: What is the role of inventory management in production planning and control?

A: Inventory management plays a critical role in production planning and control by ensuring that the right amount of inventory is available at the right time to support production schedules, while minimizing costs and waste.

Q: What is the role of quality control in production planning and control?

A: Quality control plays a critical role in production planning and control by ensuring that products meet quality standards and customer requirements. Quality control involves inspecting and testing products at various stages of the production process to identify and correct any defects or non-conformities.

Q: What is a production bottleneck?

A: A production bottleneck is a process or operation that has a lower capacity than the other processes in the production line, causing delays and backlogs in the production process.

Q: What is capacity planning?

A: Capacity planning is the process of determining the production capacity required to meet customer demand and achieve production goals, and involves evaluating and managing the resources, equipment, and labor required for production.

Q: What is lean production?

A: Lean production is a production management philosophy that focuses on maximizing efficiency, minimizing waste, and improving quality by continuously improving the production process and eliminating non-value-added activities.

Q: What is Six Sigma?

A: Six Sigma is a methodology for quality management that aims to reduce defects and variation in the production process by analyzing and improving process efficiency and effectiveness.

Q: What is Total Quality Management (TQM)?

A: Total Quality Management (TQM) is a management approach that emphasizes continuous improvement in all aspects of an organization, including the production process, to achieve customer satisfaction and improve overall performance.
