What Is MRP?

Material requirements planning (MRP) is a solution that helps you establish inventory item requirements to develop effective product production plans from start to finish.

This solution allows you to manage bill of materials (BOM), estimates, purchase planning and more in one centralized hub to streamline manufacturing operations, from collecting orders to producing merchandise and distributing them to consumers.

Brief History

Before the MRP system debuted, people maintained inventory by hand with pencil and paper.

General Electric and Rolls Royce crafted the first computerized MRP system in the early 1950s to streamline inventory management. Black & Decker was the first business to use commercialized MRP software in 1964.

In 1975, more than 700 companies used MRP systems. Today, an MRP system continuously receives upgrades to maintain inventory, manage manufacturing protocols and help other business departments.

MRP vs. ERP

ERP and MRP may sound similar on the surface, but these systems are as different as night and day.

MRP focuses on manufacturing tasks and can integrate with other solutions, such as customer relationship management (CRM), accounting and inventory management. You can also consider MRP as an ERP module, but most MRP systems are standalone.

ERP software is a suite of different modules that serve all of a company’s departments, from accounting and marketing to manufacturing and HR.

How It Works

We can break down how an MRP system works into four comprehensive steps:

1. Estimate Required Materials: Use the master production schedule to gauge product demand and required objects to craft the merchandise from bill of materials (BOMs) and work orders.
2. Distribute Stock Items: Leverage an MRP system to ascertain available stock and incoming deliveries. This software can help you make extra orders to meet your demand if significant gaps exist.
3. Schedule Production: Assess required production time, labor, machinery and production stations for each step in creating and finishing a product.
4. Supervise Processes: Govern workflows and receive notifications for delayed orders.

Primary Benefits

MRP systems have several advantages, from managing inventory items and saving time to building customer relationships.

Control Inventory

Avoid raw material shortages or overstocking to save time and money.

Let’s say you own a men’s and women’s jean factory and keep fabrics, threads, dyes and other materials in your facilities. You could have a high demand for bleach-white jeans in the spring and summer.

However, white jeans drop in demand after Labor Day (since fashion believes white after this holiday is obsolete). Your MRP can help you buy the proper inventory amounts without wasting money or buying too little and exposing yourself to shortages.

Align Purchases With Schedules

Plan for items according to your production schedule needs.

You plan to sell thousands of black leather jeans in the fall months to accentuate autumn, and Halloween looks. However, if you wait until the last minute, you may not have enough leather and other materials to create your forecasted jeans.

MRP solutions can help you plan for buying items in manageable chunks or all at once before you need them or they sell out.

Enhance Resource Distribution

Allocating the ideal resources — i.e., employees, machinery, tools, materials and so on — for each job requires careful planning. Luckily, an MRP system offers practical resource management tools to assign the best duties to the right workers to increase production.

For example, most workers are good at managing different machines during jean production. However, a few workers could also excel in loading finished products onto delivery trucks.

You can delegate outbound truck-loading to those employees who succeed while the other workers focus on the main factory floor tasks to expedite production speed.

Save Time

Allocating resources, automating inventory replenishment plans and planning production schedules saves time and money.

When you have the right resources diligently working on getting products out of warehouses to clients, you save time and diminish human errors. You also gain suitable tools for creating specific merchandise quantities.

Strengthen Customer Relationships

Boosting on-time deliveries with effective workflows ensures strong customer relationships.

When you create your jeans and deliver them to the right vendors and clients promptly, more people will want to buy your pants. Happy clients will rave about your jeans to their family, friends and social media followers, which increases orders and profitability.

Disadvantages

Everything has pros and cons, even MRP systems. Here are three disadvantages of implementing an MRP system:

• Relies Too Much on Data Accuracy: You need accurate data to initiate ideal inventory replenishment, purchasing and workflow plans. Not inputting the correct data could cause insufficient funds or wrong stock quantities.
• Expensive Implementations: Similar to ERP, implementing MRP systems can be costly in terms of money and time. You need time to migrate all existing data and allow for hidden or additional costs.
• Has Customization Restrictions: Some software vendors enable you to customize programs to align with your current needs. Some MRP providers don’t have this option, or customizations are finite with little wiggle room.

Key Features

Here’s a rundown of the best features to have in MRP systems.

BOM

Supervise and manage BOMs to review assembly methods, raw materials and more to create and fulfill client orders.

For example, you may have an order for your white, leather and maroon-colored jeans. Your BOMs will tell you how much fabric is needed and the type of materials required to complete the order.

Forecasting/Estimation

Customers have diverse needs and wants. These requirements affect product and service demand across several timeframes. Forecasting and estimation tools can improve your projections for certain quarters, months or seasons.

You can determine how many jean styles to sell in different intervals and compare forecasted against actual profits for enhanced production to avoid unsold merchandise.

Inventory Management

Managing inventory is an essential MRP function. You can understand on-hand stock with real-time data, make appropriate refill protocols and find items quickly.

If you don’t have enough fabrics for your jeans during the holiday season, your production run could fall short of your expectations, disappointing many consumers.

Purchase Planning

Understand what items are needed to complete a project and craft appropriate spending plans.

You may try jeans with hints of wool or fleece for a winter look. However, you want to buy enough materials and store them in a safe place.

You can effectively plan out how much wool you’ll need for each pair of jeans and sensibly buy your materials as required.

Customer Relationship Management (CRM)

Producing customers with the right services and products should always be your priority. CRM tools allow you to maintain customer communications with client portals and collaboration tools to improve customer relationships.

Let’s say you want customer insight for a few jean designs. You can set up a customer portal or use social media to post a poll with four ideal methods. Clients can voice their opinions so you can understand what they’re looking for in a new pair of pants.

Warehouse Management

Maintaining warehouse facilities lets you know where you keep stock items, finished products, prototypes, rejects and so on. A warehouse management system (WMS) tool helps you maintain picking, packing, order shipping and inventory.

An ideal WMS system can help you manage your jean operations across one or several facilities. Ensure your products’ movement along your supply chain pipeline in real time and catch any bottlenecks before they transform into significant issues.

Best Practices

After covering MRP system benefits, limitations and top features, here’s a brief rundown of best practices when finding and implementing this solution.

Find a Solution That Matches Your Business Needs

How do you find an MRP system that best aligns with your company’s and industry’s goals?

We offer our nine-step Lean Selection Methodology that streamlines the software buying process from start to finish. Here’s a quick overview of each step:

1. Establish: Take an internal survey of why you need new software for your practices.
2. Collaborate: Assemble an internal software selection team with a project manager, internal and external stakeholders, end users, department leaders and more.
3. Define: Meet with your team from the previous step to develop a requirements list.
4. Distribute: Compare your modules list with several vendors and shortlist the ones that are the best match.
5. Justify: Discuss these questions with your selection committee: Do we need new software? Do we need add-on modules for our current system? Or do we end the software hunt here?
6. Prove: Ask potential vendors for use cases, demos or proofs-of-concept (POCs) to showcase what their products can do.
7. Rank: Review and organize software providers based on their demo scores and total cost of ownership (TCO). You should have two to three picks that best meet your needs.
8. Negotiate: Review and discuss terms and agreements with your top-rated software provider. Seek supplemental legal counsel if a contract seems sketchy. Repeat this step if you can’t reach a compromise with this provider.
9. Sign: Shake hands, sign the contract and establish an implementation plan for your MRP system.

Integrate Your MRP With Other Systems

If you have other software, such as CRM, ERP, supply chain management and so on, find an MRP system that can integrate with your existing programs.

Centralizing your solutions into one hub offers better navigation instead of simultaneously opening multiple windows.

You may also run into an MRP that aligns with your company size and industry needs but may lack certain features. If the system merges with your other solutions, you have fewer worries.

Know Your Limits

You don’t want to bite off more than you can chew.

In other words, MRP systems could estimate how many products you could craft in a particular duration. For example, this solution could recommend developing one million pairs of jeans at the end of 30 days.

However, crafting one million pairs of jeans sounds unrealistic if you’re a mid-sized company with one or two locations,

Know your capacity limits, and don’t overdo things, even if your MRP says you should.
