Challenges of Spare Parts Supply Chain

Jun 14, 2024

In the world of business, exceptional customer service is the key to success. And because of this, it helps you build brand loyalty, too.

Henry Ford once said that a business focused on providing good service will not have to worry about profits as they will be abundant. This applies to all industries, as companies that prioritise customer service and the management of spare parts are more likely to gain loyal customers and achieve more profits.

However, managing spare parts can be difficult for many supply chain organisations because of the set of challenges they have to face.

As supply chain consultants, we understand the complexities of business operations and have identified several obstacles that can disrupt the efficiency of spare parts supply chains.

In this blog post, we will explore the key issues and challenges associated with spare parts management so that you do not have to worry about anything on your end.

Challenges of Spare Part Management

Challenges Related to Spare Parts Management

  1. Demand Forecasting :

    Forecasting of spare parts presents a unique challenge due to the need to not only predict the quantity but also the timing of when these parts will be required. Unlike other industries where demand can be more predictable and stable, spare parts may be needed more urgently without any previous demand or for a long time. This sporadic and unpredictable behaviour makes it difficult to accurately determine the right amount and type of parts to keep in stock.

  2. Strategies to Overcome this Challenge of Demand Forecasting:

    Historical Data Analysis :

    Examine historical data to recognise patterns in demand over time, including trends and seasonal fluctuations.

    Customer Relationship Management Systems (CRM) :

    CRM systems utilise customer data to gain insights into equipment usage and anticipate maintenance requirements.

    Machine Learning and Predictive Maintenance :

    Make use of artificial tools to analyse data from machines and predict when they will need maintenance so that replacement parts can be ordered in advance.

    Collaboration with Customers :

    Work together with customers by maintaining open lines of communication to understand their maintenance schedules and parts requirements.
  3. Managing Variety and Obsolescence :

    One of the major difficulties faced in managing spare parts is the wide array of parts needed to support a diverse range of products. Each product line or model often has its own specific set of parts, thus complicating the task of inventory management. Additionally, as product lines progress and advance, older parts eventually become obsolete. This calls for meticulous planning to effectively phase out the outdated stock and smoothly transition to newer parts.

  4. Strategies to Handle Parts Variety and Obsolescence:

    Standardisation :

    To streamline inventory management and decrease overall variety, it is advisable to standardise parts across different product lines whenever feasible.

    ABC Classification :

    The ABC Classification system categorises parts into three groups based on their importance and cost: A (high importance/cost), B (medium), and C (low). The main focus is on managing inventory levels efficiently for A and B category parts.

    Lifecycle Management :

    Develop a detailed strategy for discontinuing outdated parts and inform customers ahead of time so they can obtain any necessary replacements.

    Vendor-Managed Inventory :

    Partner or work with vendors to handle a portion of spare parts inventory. This further improves the inventory accuracy and minimises instances where you can run out of stock.
  5. Inventory Optimisation and Cost Control :

    You can find spare parts everywhere because they are used to maintain and assist various products at different locations, such as warehouses, offices, retailers, OEM locations, etc. Therefore, managing spare parts inventory from various global partners requires tracking the location and quantity of products at all times. Cost control involves estimating and managing demand for products. The goal is to balance having enough stock to meet customer needs without holding excess inventory. Stockouts can lead to unhappy customers and downtime while overstocking can lead to using more capital. Therefore, accurate inventory counts are crucial for success.

  6. Strategies to Overcome the Inventory and Cost Challenges:

    Safety Stock Management :

    This involves determining the most suitable amount of safety stock for each part, taking into account various factors such as lead times, demand variability, and desired service level goals.

    Minimum Order Quantities (MOQ) :

    Negotiate with suppliers to establish flexible order quantities for slow-moving parts in order to prevent excessive inventory.

    Demand Forecasting Methods :

    You must continuously improve your demand forecasting methods to ensure that you have the necessary inventory when needed.

    Collaborative Planning, Forecasting and Replenishment :

    CPFR is a strategy where companies work together with their suppliers to exchange information about demand and jointly plan inventory levels.
  7. Geographic Challenges :

    With the presence of globalisation, businesses no longer operate within a single country. Instead, they have now expanded their operations to multiple locations, catering to customers with diverse needs all across the globe. However, this geographical dispersion comes with its own set of challenges, particularly when it comes to delivering spare parts to these dispersed locations in an efficient manner. This is because of the different customs regulations, transportation infrastructure differences, and language barriers that hinder communication.

  8. Strategies to Overcome this Challenge:

    Regional Warehousing :

    It involves setting up warehouses in remote locations worldwide to decrease lead times and enhance the availability of parts for customers in specific regions.

    Third-party Logistics Providers :

    Partner with skilled 3PL providers who know global shipping and customs procedures.

    Digitalisation of Spare Parts :

    Utilise a strong logistics management system to track spare parts movement globally in real-time as part of supply chain digitalisation efforts.
  9. Counterfeiting and Quality Concerns :

    The issue of fake spare parts is becoming increasingly a growing concern in many industries. These fraudulent components are often of poor quality, posing a significant threat to equipment malfunction, potential safety risks, and, ultimately, dissatisfied customers. Thus, it is imperative to prioritise the verification of spare parts' authenticity and quality to uphold customer confidence and safeguard the reputation of the brand.

  10. Strategies to Overcome the Quality Concerns:

    Supplier Qualification :

    Thoroughly evaluate and approve potential suppliers of spare parts by reviewing their quality control procedures and certifications.

    Secure Packaging and Labelling :

    Use secure packaging that has tamper-evident features and unique identification marks on authentic parts.

    Customer Education :

    You must inform and warn your customers about the risks of using counterfeit parts while also giving them tools to recognise the right parts.
