Managing Spare Parts Inventory: Best Practices

Managing spare parts inventory is a critical component for businesses that depend on equipment uptime and service reliability. Unlike regular inventory items, spare parts often have unpredictable demand patterns, making them more challenging to manage effectively. An efficient spare parts inventory management system helps prevent stockouts that can lead to operational downtime and costly delays while also avoiding overstocking that unnecessarily ties up capital and increases holding costs.

In this blog, we’ll explore several effective strategies for managing spare parts inventory, emphasizing the importance of optimizing stock levels, maintaining service levels, and using smart tools to aid in decision-making.

For many industries—especially manufacturing, transportation, utilities, and any sector reliant on complex machinery—spare parts serve as the backbone of maintenance operations. Ineffective management can result in significant downtime when critical parts are unavailable, leading to production halts, service disruptions, and customer dissatisfaction. On the other hand, overstocking items that may not be used promptly ties up working capital, increases storage costs, and can lead to obsolescence.

Given that many spare parts experience intermittent and unpredictable demand, it is essential to have a clear and proactive strategy for managing them. Effective spare parts inventory management ensures operational efficiency, cost savings, and reliability, which can provide a competitive advantage in the marketplace.

 

Key Strategies for Managing Spare Parts Inventory

1. Forecasting Intermittent Demand. Spare parts often exhibit irregular demand patterns characterized by long periods of zero demand punctuated by sudden spikes when equipment failures occur. Traditional forecasting methods, which rely on consistent historical data trends, may not accurately predict such erratic usage. This can lead to either overstocking or stockouts.

Utilizing specialized forecasting tools like Smart IP&O’s patented intermittent demand forecasting algorithms can provide more accurate predictions. These advanced models analyze historical usage data, equipment failure rates, and maintenance schedules to adjust for demand variability. By incorporating probabilistic forecasting , machine learning, and AI techniques, now we can avoid both shortages that could halt operations and excess inventory that unnecessarily consumes resources.

2. Setting Optimal Safety Stock Levels. Safety stock is essential for mitigating the risk of stockouts, especially for critical spare parts. Safety stock should account for lead time variability, demand fluctuations, and the criticality of the part. Using systems that calculate optimal safety stock levels based on these factors ensures that your parts are available when needed without excessive overstock​. Safety stock settings should be reviewed regularly as part of an ongoing inventory optimization process.

3. Using Min/Max Inventory Policies. A common approach to spare parts inventory is using Min/Max policies, where inventory is replenished up to a maximum level once it drops below a minimum threshold. This system allows for flexibility and ensures that stock levels are maintained without requiring constant monitoring. Adjusting these parameters based on service level goals can ensure you’re not carrying excess inventory while still meeting demand​.

4. Inventory Optimization involves balancing holding costs, stockout costs, and desired service levels to achieve the most cost-effective inventory management strategy. Software solutions like Smart IP&O can simulate various demand and supply scenarios and calculate the optimal inventory policies.

By leveraging advanced AI algorithms and data analytics, Smart IP&O helps organizations determine the right inventory levels for each spare part, considering factors like demand variability, lead times, and cost constraints. This ensures that you maintain the right balance between having sufficient inventory to meet demand and minimizing the costs associated with overstocking. Moreover, optimization tools allow for continuous adjustments based on real-time data and shifting demand patterns, enabling organizations to respond proactively to market or supply chain changes.

5. Regular Review of Supplier Lead Times Supplier performance and lead times can significantly impact your spare parts strategy. Delivery delays can cause stockouts if not accounted for in your planning. Monitoring actual lead times against expected performance helps adjust reorder points and safety stock levels accordingly.  Systems like Smart IP&O provide detailed reporting on supplier performance, including lead time variability, on-time delivery rates, and quality metrics. With access to this information, you can identify potential risks in your supply chain and take proactive measures, such as finding alternative suppliers or adjusting inventory policies, to mitigate the impact of supplier unreliability.

6. Managing Obsolescence. Spare parts often become obsolete when equipment is upgraded or phased out. Holding onto obsolete inventory ties up capital and occupies valuable warehouse space. Regularly reviewing your inventory for items nearing obsolescence can prevent excess stock. Methods such as using cycle stock and safety stock calculations based on demand can help mitigate the risks of holding onto outdated inventory​.

7. Automating Inventory Processes. Automation in inventory management can significantly reduce manual errors, increase efficiency, and ensure timely replenishment of spare parts. Tools like Smart IP&O automate many forecasting, optimization, and replenishment tasks that would otherwise be labor-intensive and prone to human error.

By integrating these tools with existing  ERP systems, organizations can achieve seamless updates and adjustments based on the latest demand and supply data. Automation enables real-time visibility into inventory levels, demand trends, and supply chain disruptions, allowing for quicker decision-making and enhanced responsiveness to changes. Moreover, automation frees up personnel to focus on strategic tasks rather than routine data entry and calculations.

Managing spare parts inventory effectively ensures operational continuity and avoids unnecessary costs. By leveraging advanced forecasting tools, setting optimal safety stock levels, and using smart inventory optimization strategies, companies can minimize stockouts, reduce holding costs, and enhance overall service levels. Continuous improvement and the integration of technology into the inventory management process provide significant long-term benefits for any organization reliant on spare parts. Embracing these best practices not only contributes to operational efficiency but also supports strategic objectives such as cost reduction, customer satisfaction, and competitive advantage.

      Why MRO Businesses Need Add-on Service Parts Planning & Inventory Software

      MRO organizations exist in a wide range of  industries, including public transit, electrical utilities, wastewater, hydro power, aviation, and mining. To get their work done, MRO professionals use Enterprise Asset Management (EAM) and Enterprise Resource Planning (ERP) systems. These systems are designed to do a lot of jobs. Given their features, cost, and extensive implementation requirements, there is an assumption that EAM and ERP systems can do it all.

      For example, at a recent Maximo Utilities Working Group event, several prospects stated that “Our EAM will do that” when asked about requirements for forecasting usage, netting out supply plans, and optimizing inventory policies. They were surprised to learn it did not and wanted to know more.

      In this post, we summarize the need for add-on software that addresses specialized analytics for inventory optimization, forecasting, and service parts planning.   

      EAM Systems

      EAM systems can’t ingest forecasts of future usage – these systems simply aren’t designed to conduct supply planning and many don’t even have a place to hold forecasts. So, when an MRO business needs to net out known requirements for planned production or capital projects, an add-on application like Smart IP&O is needed.

      Inventory Optimization software with features that support planning known future demand will take project-based data not maintained in the EAM system (including project start dates, duration, and when each part is expected to be needed) and compute a period-by-period forecast over any planning horizon. That “planned” forecast can be projected alongside statistical forecasts of “unplanned” demand arising from normal wear and tear. At that point, parts planning software can net out the supply and identify gaps between supply and demand. This ensures that these gaps won’t go unnoticed and result in shortages that would otherwise delay the completion of the projects. It also minimizes excess stock that would otherwise be ordered too soon and needlessly consumes cash and warehouse space. Again, MRO businesses sometimes mistakenly assume that these capabilities are addressed by their EAM package.

      ERP Systems

      ERP systems, on the other hand, typically do include an MRP module that is designed to ingest a forecast and net out material requirements. Processing will consider current on hand inventory, open sales orders, scheduled jobs, incoming purchase orders, any bill of materials, and items in transit while transferring between sites. It will compare those current state values to the replenishment policy fields plus any monthly or weekly forecasts to determine when to suggest replenishment (a date) and how much to replenish (a quantity).

      So, why not use the ERP system alone to net out the supply plan to prevent shortages and excess? First, while ERP systems have a placeholder for a forecast and some systems can net out supply using their MRP modules, they don’t make it easy to reconcile planned demand requirements associated with capital projects. Most of the time, the data on when planned projects will occur is maintained outside of the ERP, especially the project’s bill of materials detailing what parts will be needed to support the project. Second, many ERP systems don’t offer anything effective when it comes to predictive capabilities, relying instead on simple math that just won’t work for service parts due to the high prevalence of intermittent demand. Finally, ERP systems don’t have flexible user-friendly interfaces that support interacting with the forecasts and supply plan.

      Reorder Point Logic

      Both ERP and EAM have placeholders for reorder point replenishment methods such as Min/Max levels. You can use inventory optimization software to populate these fields with the risk-adjusted reorder point policies. Then within the ERP or EAM systems, orders are triggered whenever actual (not forecasted) demand drives on-hand stock below the Min. This type of policy doesn’t use a traditional forecast that projects demand week-over-week or month-over-month and is often referred to as “demand driven replenishment” (since orders only occur when actual demand drives stock below a user defined threshold).

      But just because it isn’t using a period-over-period forecast doesn’t mean it isn’t being predictive. Reorder point policies should be based on a prediction of demand over a replenishment lead time plus a buffer to protect against demand and supply variability. MRO businesses need to know the stockout risk they are incurring with any given stocking policy. After all, inventory management is risk management – especially in MRO businesses when the cost of stockout is so high. Yet, ERP and EAM do not offer any capabilities to risk-adjust stocking policies. They force users to manually generate these policies externally or to use basic rule of thumb math that doesn’t detail the risks associated with the choice of policy.

      Summary

      Supply chain planning functionality such as inventory optimization isn’t the core focus of EAM  and ERP. You should leverage add-on planning platforms, like Smart IP&O, that support statistical forecasting, planned project management, and inventory optimization. Smart IP&O will develop forecasts and stocking policies that can be input to an EAM or ERP system to drive daily ordering.

        Why MRO Businesses Should Care About Excess Inventory

        Do MRO companies genuinely prioritize reducing excess spare parts inventory? From an organizational standpoint, our experience suggests not necessarily. Boardroom discussions typically revolve around expanding fleets, acquiring new customers, meeting service level agreements (SLAs), modernizing infrastructure, and maximizing uptime. In industries where assets supported by spare parts cost hundreds of millions or generate significant revenue (e.g., mining or oil & gas), the value of the inventory just doesn’t raise any eyebrows, and organizations tend to overlook massive amounts of excessive inventory.

        Consider a public transit agency.  In most major cities, the annual operating budgets will exceed $3 billion.  Capital expenses for trains, subway cars, and infrastructure may reach hundreds of millions annually. Consequently, a spare parts inventory valued at $150 million might not grab the attention of the CFO or general manager, as it represents a small percentage of the balance sheet.  Moreover, in MRO-based industries, many parts need to support equipment fleets for a decade or more, making additional stock a necessary asset. In some sectors like utilities, holding extra stock can even be incentivized to ensure that equipment is kept in a state of good repair.

        We have seen concerns about excess stock arise when warehouse space is limited. I recall, early in my career, witnessing a public transit agency’s rail yard filled with rusted axles valued at over $100,000 each.  I was told the axles were forced to be exposed to the elements due to insufficient warehouse space. The opportunity cost associated with the space consumed by extra stock becomes a consideration when warehouse capacity is exhausted. The primary consideration that trumps all other decisions is how the stock ensures high service levels for internal and external customers.  Inventory planners worry far more about blowback from stockouts than they do from overbuying.  When a missing part leads to an SLA breach or downed production line, resulting in millions in penalties and unrecoverable production output, it is understandable.

        Asset-intensive companies are missing one giant point. That is, the extra stock doesn’t insulate against stockouts; it contributes to them. The more excess you have, the lower your overall service level because the cash needed to purchase parts is finite, and cash spent on excess stock means there isn’t cash available for the parts that need it.  Even publicly funded MRO businesses, like utilities and transit agencies, acknowledge the need to optimize spending, now more than ever.  As one materials manager shared, “We can no longer fix problems with bags of cash from Washington.”  So, they must do more with less, ensuring optimal allocation across the tens of thousands of parts they manage.

        This is where state-of-the-art inventory optimization software comes in, predicting the required inventory for targeted service levels, identifying when stock levels yield negative returns, and recommending reallocations for improved overall service levels.  Smart Software has helped asset intensive MRO based businesses optimize reorder levels across each part for decades.

          Top Differences Between Inventory Planning for Finished Goods and for MRO and Spare Parts

          What’s different about inventory planning for Maintenance, Repair, and Operations (MRO) compared to inventory planning in manufacturing and distribution environments? In short, it’s the nature of the demand patterns combined with the lack of actionable business knowledge.

          Demand Patterns

          Manufacturers and distributors tend to focus on the top sellers that generate the majority of their revenue. These items typically have high demand that is relatively easy to forecast with traditional time series models that capitalize on predictable trend and/or seasonality.  In contrast, MRO planners almost always deal with intermittent demand, which is more sparse, more random, and harder to forecast.  Furthermore, the fundamental quantities of interest are different. MRO planners ultimately care most about the “when” question:  When will something break? Whereas the others focus on the “how much” question of units sold.

           

          Business Knowledge

          Manufacturing and distribution planners can often count on gathering customer and sales feedback, which can be combined with statistical methods to improve forecast accuracy. On the other hand, bearings, gears, consumable parts, and repairable parts are rarely willing to share their opinions. With MRO, business knowledge about which parts will be needed and when just isn’t reliable (excepting planned maintenance when higher-volume consumable parts are replaced). So, MRO inventory planning success goes only as far as their probability models’ ability to predict future usage takes them. And since demand is so intermittent, they can’t get past Go with traditional approaches.

           

          Methods for MRO

          In practice, it is common for MRO and asset-intensive businesses to manage inventories by resorting to static Min/Max levels based on subjective multiples of average usage, supplemented by occasional manual overrides based on gut feel. The process becomes a bad mixture of static and reactive, with the result that a lot of time and money is wasted on expediting.

          There are alternative planning methods based more on math and data, though this style of planning is less common in MRO than in the other domains. There are two leading approaches to modeling part and machine breakdown: models based on reliability theory and “condition-based maintenance” models based on real-time monitoring.

           

          Reliability Models

          Reliability models are the simpler of the two and require less data. They assume that all items of the same type, say a certain spare part, are statistically equivalent. Their key component is a “hazard function”, which describes the risk of failure in the next little interval of time. The hazard function can be translated into something better suited for decision making: the “survival function”, which is the probability that the item is still working after X amount of use (where X might be expressed in days, months, miles, uses, etc.). Figure 1 shows a constant hazard function and its corresponding survival function.

           

          MRO and Spare Parts function and its survival function

          Figure 1: Constant hazard function and its survival function

           

          A hazard function that doesn’t change implies that only random accidents will cause a failure. In contrast, a hazard function that increases over time implies that the item is wearing out. And a decreasing hazard function implies that an item is settling in. Figure 2 shows an increasing hazard function and its corresponding survival function.

           

          MRO and Spare Parts Increasing hazard function and survival function

          Figure 2: Increasing hazard function and its survival function

           

          Reliability models are often used for inexpensive parts, such as mechanical fasteners, whose replacement may be neither difficult nor expensive (but still might be essential).

           

          Condition-Based Maintenance

          Models based on real-time monitoring are used to support condition-based maintenance (CBM) for expensive items like jet engines. These models use data from sensors embedded in the items themselves. Such data are usually complex and proprietary, as are the probability models supported by the data. The payoff from real-time monitoring is that you can see trouble coming, i.e., the deterioration is made visible, and forecasts can predict when the item will hit its red line and therefore need to be taken off the field of play. This allows individualized, pro-active maintenance or replacement of the item.

          Figure 3 illustrates the kind of data used in CBM. Each time the system is used, there is a contribution to its cumulative wear and tear. (However, note that sometimes use can improve the condition of the unit, as when rain helps keep a piece of machinery cool). You can see the general trend upward toward a red line after which the unit will require maintenance. You can extrapolate the cumulative wear to estimate when it will hit the red line and plan accordingly.

           

          MRO and Spare Parts real-time monitoring for condition-based maintenance

          Figure 3: Illustrating real-time monitoring for condition-based maintenance

           

          To my knowledge, nobody makes such models of their finished goods customers to predict when and how much they will next order, perhaps because the customers would object to wearing brain monitors all the time. But CBM, with its complex monitoring and modeling, is gaining in popularity for can’t-fail systems like jet engines. Meanwhile, classical reliability models still have a lot of value for managing large fleets of cheaper but still essential items.

           

          Smart’s approach
          The above condition-based maintenance and reliability approaches require an excessive data collection and cleansing burden that many MRO companies are unable to manage. For those companies, Smart offers an approach that does not require development of reliability models. Instead, it exploits usage data in a different way. It leverages probability-based models of both usage and supplier lead times to simulate thousands of possible scenarios for replenishment lead times and demand.  The result is an accurate distribution of demand and lead times for each consumable part that can be exploited to determine optimal stocking parameters.   Figure 4 shows a simulation that begins with a scenario for spare part demand (upper plot) then produces a scenario of on-hand supply for particular choices of Min/Max values (lower line). Key Performance Indicators (KPIs) can be estimated by averaging the results of many such simulations.
