Material Requirements Planning) an information system that determines what assemblies must be built and what materials must be procured in order to build a unit of equipment by a certain date. It queries the bill of materials and inventory databases to derive the necessary elements.
What Does Materials Requirement Planning (MRP) Mean?
One of the first software based integrated information systems designed to improve productivity for businesses. A materials requirement planning (MRP) information system is a sales forecast-based system used to schedule raw material deliveries and quantities, given assumptions of machine and labor units required to fulfil a sales forecast.
MRP was the earliest of the integrated information systems dealing with improvements in productivity for businesses with the use of computers and software technology to provide meaningful data to managers. With the advent of such systems, production efficiency could be greatly improved. As the analysis of data and the technology to capture it became more sophisticated, more comprehensive systems were developed to integrate MRP with other aspects of the manufacturing process.
Benefits of MRP Manufacturing Requirements Planning
The MRP system outputs a variety of information that can be used by the company, both for the planning side and the management side of the factory operations. These outputs include order release notices for the placement of orders that may have been planned by the MRP simulator system. The capacity and master schedule need to be managed correctly to help reduce the workload and maximize the effectiveness. Management has a big responsibility in this and how they choose to plan ahead and how effective they are, will in turn effect their decisions on the right approach and how effective the MRP system is. If certain areas become stressed and overloaded, jobs may end up being pushed back past their due date and end up being late. Planning is very important to help the company become more efficient, reduce costs and increase profits. Information systems are a competitive tool when running alongside traditional stock control systems.
A computerized MRP system is reliant on the fact that the demand for low-level components is brought about from the production of an end product of which the production level is planned. The system itself will make it easy to put together the production schedule saving vast amount of money that would otherwise be spent on labour time to do the same activity. MRP does not take into account the level of capacity of what can or cannot be handled by the shop floor. MRP is best used in manufacturing companies with products that have lots of assemblies and is based on what is to be sold, working backwards from a delivery date, using the just in time concept (JIT). If the MRP system is controlled and designed well, inventory levels can be reduced, by reducing the amount of work-in-progress (WIP).
An MRP system improves customer service by reducing the number of late orders, creates higher levels of productivity, and helps the company respond to changes in demand much quicker. If MRP is implemented correctly it has many benefits that will help improve productivity etc continuously. Here is a summary of the benefits below:
- Reduced Inventory with fewer (none) shortages
- Improved Customer Service
- Improved Direct Labour Productivity
- Reduced Purchasing Cost
- Reduced Traffic Cost
- Reduced Obsolescence
- Reduced Overtime
- Having the numbers to run the business
- Having accountability throughout the organisation
- Improved Quality of Life
Definition and Explanation of Direct Materials Budget
Direct materials budget is prepared after computing production requirements by preparing a production budget. Direct materials budget or materials budgeting details the raw materials that must be purchased to fulfil the production requirements and to provide for adequate inventories. The required purchases of raw materials are computed as follows:
|

Preparing a budget of this kind is one step in a company's overall material requirements planning (MRP). MRP is an operations management tool that uses a computer to help manage materials and inventories, The objective of material requirements planning (MRP) is to ensure that the right materials are on hand, in the right quantities, and at the right time to support the production budget.

Notes
- Ten percent of the next quarter’s needs. Example: Second-quarter production needs are 480,000 pounds. Desired ending inventory for first quarter = 10% of 480,000 = 48,000 pounds. Ending inventory of 22,500 pounds for the fourth quarter is assumed.
- Cash payments of the last year’s fourth-quarter materials purchases.
- $47,500 × 50%; $47,500 × 50%.
- $97,200 × 50%; $97,200 × 50%.
- $102,900 × 50%; $102,900 × 50%.
- $55,800 × 50%. Unpaid fourth-quarter purchases appear as accounts payable on the company’s year-end balance sheet.
Explanation of the Direct Materials Budget for Hamilton Inc.
The only raw materials include in this budget is high fructose sugar, which is the major ingredient in popsicles (finished goods of Hamilton Inc.) other than water. The remaining raw materials are relatively insignificant and are included in variable manufacturing overhead. As with finished goods, management would like to maintain some minimum inventories of raw materials as cushion. In this case, management would like to maintain ending inventories of sugar equal to 10% of the following quarter's production needs.
The first line in the direct materials budget contains the required production for each quarter, which is taken directly from the production budget (see production budget page). Looking at the first quarter, since the schedule of production budget calls for the production of 14,000 cases of popsicles (finished goods of Hamilton Inc.) and each case requires 15 pounds of sugar, the total production needs are for 210,000 pounds of sugar (14,000 cases × 15 pounds per case). In addition, management wants to have ended inventories of 48,000 pounds of sugar, which is 10% of the following quarter's needs of 480,000 pounds. Consequently, the total needs are for 258,000 pounds (210,000 pounds for the current quarter's production plus 48,000 pounds for the desired ending inventory). However, since the company already has 21,000 pounds in beginning inventory, only 237,000 pounds of sugar (258,000 pounds – 21,000 pounds) will need to be purchased. Finally, the cost of the materials purchases is determined by multiplying the amount of raw materials to be purchased by the cost per unit of the raw materials. In this case, since 237,000 pounds of sugar will have to be purchased during the first quarter and sugar costs $0.20 per pound, the total cost will be $47,400 (237,000 pounds × $0.20 per pound). As with the production budget, the amounts listed under the year column are not always just the sums of the quarterly amounts. The desired ending inventory of raw materials for the year is the same as the desired ending inventory of raw materials for the fourth quarter. Likewise, the beginning inventory of the raw materials for the year is the same as the beginning inventory of raw materials for the first quarter. Direct materials budget is usually accompanied by a schedule of expected cash disbursements for raw materials.
This schedule is needed to prepare the overall cash budget. Disbursement of raw materials consists of payments for purchases on account in prior periods plus any payments for purchases in the current budget period. Direct materials budget in our example includes such a schedule of expected cash disbursements. Ordinarily, companies do not immediately pay their suppliers. At Hampton Freeze Inc. the policy is to pay for 50% of purchases in the quarter in which the purchase is made and 50% in the following quarter, so while the company intends to purchase $47,400 worth of sugar in the first quarter, the company will only pay for half, $23,700, in the first quarter and the other half will be paid in the second quarter. The company will also pay $25,800 for sugar acquired in the previous quarter, but not yet paid for. This is the beginning balance in the accounts payable. Therefore, the total cash disbursements for sugar in the first quarter are $49,500--the $25,800 payment for sugar acquired in the previous quarter plus the $23,700 payment for sugar acquired during the first quarter.
Budget Planning
Budget planning is the process by which a company or individuals evaluate their earnings and expenses and project their monetary intakes and outtakes for the future. The goal is to lay out all necessary components and brainstorm future goals. Budget planning may be completed in one meeting or it may take weeks of evaluating available data to finalize.
- Revenues - Revenues are earnings from sales, less the cost of goods sold. In a personal budget, it is wages. During the budget planning process, use historical data, such as wage stubs and prior year financial statements, to set a baseline, then consider the future. Do you anticipate an increase? What costs will be associated with this increase? For example, if you intend to produce more widgets, how many man hours will it take and how much will materials cost to earn the extra revenue?
- Expenses - The second half of the budget is expenses. Begin with the expenses for the previous year, then adjust for increased usage, streamlining and inflation. This is a good time to negotiate new contracts with vendors and to look for ways to achieve cost savings. Remember to budget for unexpected expenses, such as repairs and gifts. Remember to allow for entertainment and annual expenses, such as insurance premiums and winter snow removal.
- Call to Action - Use the budget planning process to set goals and stress the importance of living within a budget. Have everyone involved in the process commit to working toward a successful financial year. Follow up periodically with feedback. Compare actual results for the month or quarter to the budget. Where did you succeed and where did you fail? Use the information to improve your future budgeting. A budget is only useful when it is actively put to use.
- Conservative Forecasting - Forecasting future income and expenses should be conservative in nature. This means any amounts that you are estimating; you should overestimate expenses and underestimate income slightly. Think of it as a realistic but worse-case scenario. It is much easier to find ways to spend extra money than it is to replace income that is not earned. Combine this with a possible high debt-to-income ratio or a bad credit score and you may be headed for bankruptcy.
- Flexibility - Budgets are designed for flexibility. As you find out actual numbers, such as wage increases received after the budget is finalized, update the budget going forward. The more accurate you maintain the budget, the more use you will get out of it. Be ready to revisit the budget planning process periodically and consider budgeting for more than a year in the future. A five-year plan can help you keep focused on long-term goals.
