- Contracted service levels and customer contracts determine the overall parts distribution and required service response network. When there is either equipment downtime, caused by a failing part, or when equipment consumables are suddenly out-of-stock, equipment is no longer generating value for end-customers. There is very little tolerance for inventory back-orders since non-performing equipment results in downtime costs that can far outweigh the cost of the replacement part.
- Service parts component demand is often manifested in intermittent or lumpy demand signals, caused by actual equipment operational conditions or changes in operating environment. That means planning in an environment of long-tail demand, parts that exhibit larger numbers of variability, lumpy or seasonality focused demand patterns. Traditional forecasting or demand planning techniques are often ineffective in planning parts demand in such environments. That’s because SPP is far more concentrated in individual item-level planning as contrasted to product family or aggregated planning techniques. SPP planning models feature higher stock keeping unit (SKU) counts and associated long-tail demand planning computations than traditional supply chain planning models. Algorithms that capture actual parts demand, or plan for future demand need to be far more sophisticated in item level and shipping location mathematical modeling.
- Service parts networks require the need for multi-echelon and multi-tiered inventory stocking strategies tied to more predictive parts demand. Long-tail demand can be best managed by planning that factors item level and shipping location simultaneously. SPP must therefore be able to effectively manage and optimize inventory within such multi-echelon stocking environments.

Editor’s Note: This week we have a guest post from Bob Ferrari, Managing Director of the Ferrari Consulting and Research Group. This blog first appeared in Supply Chain Matters. It is the second in a series on how companies can build foundational service parts planning technology to prepare for the Internet of Things (IoT).
In a previous blog, I declared that one of the most promising line-of-business areas that will benefit from Internet of Things (IoT) enabled technologies applied to supply chain management will be equipment services management, especially service and spare parts management.
A longstanding challenge in service or replenishment parts planning and management has always been the ability to forecast item-level demand when such demand is sporadic or sudden. Now consider the opportunities to have demand-driven or predictive failure data and information emanating directly from the physical equipment.
But with any major business transformation, there are always foundational capabilities that come first. In the specific area of IoT enabled equipment and services management, a foundational capability is usually the need for a robust, responsive, and analytically-driven service parts planning (SPP) capability.
Yet an unfortunate reality is that many manufacturing and services organizations with lower levels of process maturity have not recognized the differing process and decision-making needs required for responsive and effective SPP. Considering a leap to an IoT enabled service management business model will likely expose this weakness.
What Makes Service Parts Planning Different?
Three fundamental differences often found in SPP are the following:
