Introduction

Within the complex world of contemporary supply chain management, demand fluctuations play a crucial role in determining the flexibility and durability of a business. The COVID-19 epidemic caused a dramatic change in demand dynamics. Companies initially anticipated a drop in customer demand, so they needed to prepare for an unheard-of spike (Queiroz et al., 2020). The risks present in current supply chain infrastructures were exposed by this unexpected disruption, which made a thorough investigation of inventory management techniques necessary. Thus, the following study examines how demand variations affect various inventory systems, paying particular emphasis to the difficulties that just-in-time (JIT) systems and conventional make-to-stock strategies encounter.

A key question drives this research: What are the implications for supply chain dynamics when demand changes ripple through different inventory systems? The study has two main objectives. The main aim is to lay out the specific difficulties that Just-in-time (JIT) systems and conventional make-to-stock procedures have while managing unanticipated changes in demand. Moreover, the investigation attempts to comprehend the various impacts of variations in order on the profitability of specific items in an organization (Strandberg, 2022). By closely examining these variables, the study seeks to provide helpful guidance to academics and practitioners alike, fostering a deeper comprehension of how to address the difficulties presented by dynamic customer demand. This study is crucial for helping companies in building strong supply chains.

Literature Review

Inventory Management Principles

As explained by Slack et al. (2013), the fundamental principles of inventory management highlight the critical function stocks fulfill in balancing the time-related mismatches that result from the interaction of supply and demand. Acting as an essential cushion, inventories are crucial in mitigating disparities and offering enterprises a tactical means of managing unplanned disruptions (Raj et al., 2022). This fundamental idea highlights how dynamic inventory management is, presenting it as more than just a static storage element; it is a flexible and responsive system essential to maintaining operational continuity in the face of fluctuating market conditions.

The literature explores the nuances of the reasoning behind keeping inventories in greater detail, revealing a complex environment beyond simple time modifications. In addition to acting as a cushion against expected variations, inventories protect the delicate equilibrium between supply and demand from sporadic and unanticipated interruptions. This complex approach emphasizes how checklists serve multiple purposes, including risk reduction, operational adaptability, and the capacity to react quickly to changes in the market (PlanetTogether, 2021). As such, this idea is fundamental to understanding the difficulties caused by variations in demand. Slack et al.’s principles essentially lay the foundation for an all-encompassing approach to inventory management that goes beyond traditional paradigms, stressing the need for organizations to develop and implement flexible strategies that can skillfully navigate the complexities introduced by dynamic shifts in market demand. It emphasizes the urgent need for strategic inventory management and the imperative for organizations to cultivate flexibility and adaptability within their inventory systems.

Impact on JIT and Make-to-Stock Systems

The review of the literature digs deeply into the complex effects of demand variations on just-in-time (JIT) systems, using Toyota as an example of the industry standard. JIT systems (The Investopedia Team, 2020), which were painstakingly created to reduce inventory levels and streamline production procedures, experienced significant difficulties when faced with an unanticipated spike in demand during the extraordinary circumstances of the COVID-19 epidemic. It was clear that JIT systems were inherently vulnerable to sudden changes in order, which led to supply chain bottlenecks and made it extremely difficult to stick to production schedules. This unexpected disruption forced a reassessment of JIT systems’ adaptability, revealing the delicate balance they must maintain between operational effectiveness and the volatility of market demand.

On the other hand, conventional make-to-stock strategies, based on the strategic idea of keeping inventory levels in line with anticipated demand, needed help finding a delicate middle ground between the dangers of overstocking and the hazards of stockouts. The literature reveals the complex dynamics present in these various inventory paradigms, illuminating how they individually react to and handle the complexity brought about by variations in demand (Zhang et al., 2020). This investigation highlights the disparate approaches used by JIT and make-to-stock systems, exposing their distinct advantages and disadvantages in the face of shifting market circumstances. The knowledge gained from this literature analysis helps to provide a thorough grasp of how different inventory systems deal with demand changes, laying the groundwork for further investigation of strategic suggestions and related risks.

Profitability and Product-Specific Impact

Kraljic’s procurement positioning model provides a strategic compass for evaluating the complex relationship between demand changes and a company’s profitability in the context of supply chain dynamics. The model offers a more nuanced understanding of strategic goods, which are characterized by a high supply risk and an effect on the overall profitability of a corporation (Dabhilkar et al., 2016). These strategic goods, which are frequently essential parts of a company’s product line, become focus points susceptible to disruptions when faced with market demand changes. Thus, Kraljic’s model emphasizes how important it is for businesses to identify the strategic importance of particular products within their lines and to take preemptive measures to control the risks associated with demand changes.

This strategic lens emphasizes how crucial it is to distinguish items according to their unique qualities and strategic significance within the company structure. The body of research highlights the necessity of an individualized inventory control strategy that considers the inherent unpredictability of how different products are affected by changes in demand. Acknowledging the variety of these impacts to guide strategic decision-making processes properly becomes essential. Identifying the numerous ways that changing market conditions affect different products becomes a strategic necessity for businesses as they manage the complexity of these situations. This knowledge creates the foundation for companies to customize their inventory management plans, reducing the risk of fluctuating demand and increasing overall profitability. Essentially, Kraljic’s model offers an all-encompassing structure that motivates firms to implement a customized and strategic approach to inventory management, aligning their strategies with the unique characteristics and criticality of each product within their portfolio.
