Questions Asked in Familiarity with ERP and MRP Systems Interview
Q 1. Explain the difference between ERP and MRP systems.
While both ERP and MRP systems aim to improve operational efficiency, they differ significantly in scope. Think of MRP as a specific tool within the larger toolbox that is ERP.
MRP (Material Requirements Planning) focuses solely on production planning and inventory control. It calculates the materials needed for production based on a master production schedule, ensuring that the right materials are available at the right time. It’s primarily concerned with the efficient flow of materials.
ERP (Enterprise Resource Planning), on the other hand, is a much broader system that integrates all aspects of a business, including planning, purchasing, inventory, sales, marketing, finance, and human resources. It provides a holistic view of the entire organization, facilitating better decision-making across departments.
In essence, MRP is a component often integrated within a larger ERP system. A company might use a standalone MRP system for simpler needs, but larger, more complex organizations almost always opt for a comprehensive ERP system which incorporates MRP functionality among its many modules.
Q 2. Describe the key modules within an ERP system.
The specific modules within an ERP system can vary depending on the vendor and the company’s needs, but some key modules commonly found include:
- Finance and Accounting: Handles general ledger, accounts payable, accounts receivable, financial reporting, budgeting, and financial consolidation.
- Human Capital Management (HCM): Manages employee information, payroll, benefits, recruitment, and performance management.
- Supply Chain Management (SCM): Oversees procurement, inventory management, production planning (often including MRP), warehousing, and distribution.
- Customer Relationship Management (CRM): Manages customer interactions, sales leads, marketing campaigns, and customer service.
- Manufacturing: Specifically for manufacturing companies, this module handles production scheduling, quality control, and maintenance.
- Project Management: For organizations that handle projects, this module aids in planning, tracking, and reporting on projects.
These modules are interconnected, allowing for seamless data flow across departments. For example, information about a sale (CRM) can automatically update inventory levels (SCM) and trigger the purchase of additional materials (SCM), which then impacts financial reporting (Finance and Accounting).

Q 5. How does MRP contribute to effective inventory management?
MRP significantly contributes to effective inventory management by optimizing inventory levels. It does this by:
- Forecasting Demand: MRP uses sales forecasts and production schedules to predict future demand for materials.
- Calculating Material Needs: Based on the forecast, MRP calculates the exact quantity of each material required for production at specific times.
- Scheduling Purchases: MRP generates purchase orders for materials, ensuring timely delivery.
- Minimizing Stockouts and Excess Inventory: By accurately forecasting demand and scheduling purchases, MRP helps reduce the risk of stockouts (running out of materials) and prevents the accumulation of excess inventory, thereby reducing storage costs and minimizing waste.
For example, a clothing manufacturer using MRP can accurately predict the amount of fabric, buttons, and zippers needed for each clothing line based on sales forecasts and production schedules. This prevents overstocking certain materials while ensuring there are enough materials on hand to prevent production delays.
Q 6. Explain the concept of Material Requirements Planning (MRP).
Material Requirements Planning (MRP) is a production planning and inventory control system. It’s a method to determine the materials needed to manufacture a product, when they are needed, and how many of each item should be ordered or produced. It relies on three primary inputs:
- Bill of Materials (BOM): A list of all the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an end product.
- Master Production Schedule (MPS): A schedule specifying the quantity of each end product to be manufactured over a given period.
- Inventory Records: Information on the current inventory levels of all items, including raw materials, work-in-process, and finished goods.
Using these inputs, MRP calculates the precise quantities of materials needed for each production run, generating purchase orders and production schedules. This ensures that the necessary materials are available when needed, minimizing delays and maximizing efficiency.
Q 7. Describe different MRP methods (e.g., rough-cut, capacity requirements planning).
Different MRP methods offer varying levels of detail and sophistication:
- Rough-Cut Capacity Planning (RCCP): This is a high-level planning technique that uses aggregated data to assess whether the overall production capacity is sufficient to meet the master production schedule. It doesn’t delve into the specifics of individual materials or operations.
- Capacity Requirements Planning (CRP): This method determines the capacity required to meet the detailed production schedule generated by MRP. It considers factors like machine availability, labor hours, and other resources, helping to identify potential capacity bottlenecks.
- Material Requirements Planning (MRP): As described earlier, this calculates the exact quantities and timing of material needs for production, generating purchase orders and scheduling activities.
- Closed-Loop MRP: This advanced method incorporates feedback from the shop floor into the MRP system. This allows for real-time adjustments to the production schedule and material requirements based on actual progress and any unexpected issues.
The choice of MRP method depends on factors such as the complexity of the manufacturing process, the level of detail required for planning, and the available resources.
Q 8. How does MRP integrate with other business processes?
MRP (Material Requirements Planning) doesn’t exist in isolation; it’s deeply integrated with numerous other business processes. Think of it as the central nervous system for production planning, constantly interacting with other systems to ensure smooth operations.
Sales & Marketing: MRP receives sales forecasts and customer orders, which are crucial for determining production needs. A surge in orders triggers MRP to plan for increased material procurement and production scheduling.
Purchasing: MRP generates purchase requisitions based on the calculated material needs. It interacts with the purchasing system to manage supplier relationships, track orders, and ensure timely delivery of raw materials.
Inventory Management: MRP constantly interacts with inventory levels to determine what needs to be produced, purchased, or possibly disposed of due to obsolescence. It helps optimize stock levels, minimizing storage costs and preventing stockouts.
Production Planning & Scheduling: This is the core function. MRP schedules production runs, allocating resources efficiently and considering factors like machine availability, labor capacity, and production lead times. It directly informs the production floor about what to make and when.
Finance & Accounting: MRP data feeds into cost accounting, providing accurate cost estimations for projects and products. It helps with budget planning and variance analysis by tracking material costs and production efficiency.
For instance, in a furniture manufacturing company, a large order for custom-designed chairs would trigger the MRP system to automatically generate purchase orders for the required wood, fabric, and hardware. It would also schedule the production process, ensuring that the appropriate machinery and personnel are allocated. Finally, the system would update inventory levels and provide the accounting department with the cost of fulfilling the order.
Q 9. What are the key performance indicators (KPIs) used to measure ERP/MRP system effectiveness?
