The Growth Of The Service Economy Has Seen Even Traditional Product

The growth of the service economy has led traditional product-focused companies to pursue service design to add value to their offerings. This involves understanding the differences between product design and service design, comparing their processes, and explaining why these approaches are distinct. Additionally, the discussion involves Materials Requirements Planning (MRP), specifically whether it is a push-based or pull-based system, the characteristics of each within supply chain management, their short-term and long-term implications, and which program is most frequently implemented, supported by relevant examples and citations.

The transition from a purely product-oriented economy to a service-oriented one has significantly influenced how companies approach their offerings. Traditional product companies now integrate service design principles to enhance customer value, foster loyalty, and differentiate themselves in competitive markets. Understanding the fundamental differences between product design and service design is essential to appreciating the distinct processes that drive each approach and their implications.

Product Design vs. Service Design

Product design focuses on the creation of tangible goods that can be manufactured and stored for future sale. It involves engineering, material selection, aesthetic considerations, and functional features to optimize performance and consumer appeal. The process is often linear, beginning with ideation, prototype development, testing, and finally, production (Ulrich & Eppinger, 2016). The primary goal is to develop a physical item that meets customer needs and specifications efficiently.

Service design, on the other hand, concentrates on intangible offerings, emphasizing customer experience, interaction, and service delivery processes. It involves designing service delivery systems, touchpoints, and customer interactions to ensure consistency and quality. Service design is iterative and customer-centric, often requiring continuous feedback and adjustments to improve service quality (Meyers & de VAT, 2017). The process includes understanding customer journeys, designing front-stage and back-stage processes, and training personnel—highlighting a more holistic and dynamic approach compared to product design.

Differences in Processes and Underlying Principles

The key differences between product and service design processes stem from their nature. Product design typically involves a clear, upfront planning phase with a focus on tangible outputs, supply chain coordination, and manufacturing efficiency. It is largely a supply-driven process where the company determines the specifications and produces the item accordingly.

Conversely, service design prioritizes customer needs and encounters, often requiring a flexible, adaptive approach (Shostack, 1984). The process is often co-created with customers, and the delivery depends significantly on human interactions and organizational capabilities. The intangible nature of services means that quality is judged based on experience, making service design highly sensitive to customer perceptions and organizational consistency.

Materials Requirements Planning (MRP): Push versus Pull Systems

Materials Requirements Planning (MRP) is a production planning system that ensures materials are available for production and products are available for delivery, optimizing inventory levels and reducing waste. MRP is considered a push-based system because it operates based on forecasts and schedules established centrally by the master production schedule (MPS). MRP predictions "push" materials into the production process to meet anticipated demand (Evans & Lindsay, 2014).

In contrast, pull-based programs, such as Just-In-Time (JIT), only produce or order materials in response to actual customer demand. These systems "pull" inventory through the supply chain, reducing excess stock, lowering storage costs, and increasing responsiveness (Slack et al., 2010).

Implications of Push and Pull Systems

Short-term implications of push systems include high inventory costs, risk of obsolescence, and potential mismatches between supply and demand if forecasts are inaccurate. However, they are effective for stable demand and allow for economies of scale in production and bulk purchasing.

Long-term implications include the risk of overstocking or stockouts if the forecasted demand deviates significantly from reality. They may also foster a culture less responsive to actual customer needs.

Pull systems generally reduce inventory costs and increase flexibility but may lead to delays if demand exceeds supply unexpectedly. They are better suited for environments with variable demand or high product customization, providing a more responsive supply chain.

Most Commonly Implemented Program in Supply Chains

Despite the benefits of pull systems, most supply chains historically have relied on push-based MRP due to its predictability and control capabilities. However, there has been a shift toward hybrid models that combine push and pull principles to optimize efficiency and responsiveness.

For example, large manufacturers like Toyota utilize a hybrid approach integrating JIT with traditional MRP systems to balance inventory costs and service levels (Ohno, 1988). This approach exemplifies a practical implementation where manufacturing forecasts trigger raw material orders, but final assembly responds to actual customer orders.

Conclusion

The evolution of companies’ strategies illustrates how understanding the differences between product and service design is crucial for competitive advantage in a service-driven economy. Meanwhile, supply chain management practices such as MRP must adapt to market demands and operational realities. Although push-based systems dominate historically, the trend toward leaner, more responsive supply chains highlights the increasing adoption of hybrid and pull-based models to meet modern customer expectations.
