Comparative Advantage and PLM in Global Apparel Production

Comparative advantage is one of the most essential concepts in economics. This principle is based on the fact that countries and companies can achieve benefits through greater productivity by each specializing in goods and services where they have relatively more productive capacity. By specializing and then trading for other goods and services not produced as efficiently, there are mutual benefits to all countries (firms) involved.

The apparel industry illustrates this principle extremely well by utilizing a fragmented global supply chain (many different regions of the world producing clothing) due to the coordination tools available digitally to coordinate across these international supply chains; in this case, PLM for apparel industry.

In traditional supply chains, firms would design clothing items, source the fabrics and materials used to manufacture them, and manufacture and distribute (retail) all within the same country. However, due to regional and country differences in wage rates, infrastructure, and skill levels, there are powerful reasons for firms to create internationally fragmented supply chains. As a general rule of thumb, higher wage nations will focus their efforts on developing new products and the marketing of these product offerings. Lower wage nations will concentrate on manufacturing and assembling the finished good. Each country benefits from each country's comparative advantage (that is, from producing particular products with the lowest opportunity cost) by focusing on the relatively lower cost opportunity.

he economic forces that are operating behind this system are driven primarily by differences in labour costs and productivity. For example, countries such as Bangladesh and Vietnam have established a competitive advantage in garment manufacturing because of their relatively low wage structures and large numbers of skilled labourers. Currently, Bangladesh is exporting over $45 billion worth of apparel each year, making it one of the top exporters of apparel worldwide. These figures illustrate how comparative advantage shapes global trade patterns.

However, breaking production down into multiple stages in different countries creates significant coordination challenges when producing apparel. The process of producing apparel consists of many steps, which include conceptualisation, sourcing fabric, sampling, actual production, quality control and logistics. All of these steps could happen in different geographic locations and are part of a global value added chain. Without proper coordination of all these fragmented stages of production, it would lead to inefficiencies, delays, and expensive mistakes.

Therefore, this is where PLM systems will provide economic benefit. PLM centralises product information, timelines, and communications, allowing companies to manage the outsourcing and fragmentation of their production processes more effectively. Design changes can be made by designers in real-time, suppliers can respond to requests almost immediately, and manufacturers can revise production schedules without any delays. As a result, this will reduce the costs associated with coordinating, while ensuring that the benefits of comparative advantage are not eroded due to operational inefficiencies.

Global fashion brands, like many others, design their collections in major urban cities (e.g., New York City, London) utilizing fabric from Asia and finished products made in countries such as India or Vietnam. As a result of this type of operational complexity, these businesses must rely on their PLM systems to ensure that all aspects of their operations remain synchronized. Without these types of systems in place, managing multiple suppliers as well as multiple production facilities would be exceedingly difficult, leading to decreased efficiency and increased cost.

The use of PLM systems also highlights how much focus is placed on establishing a superior market presence, particularly within the fast fashion sector. To keep pace with the competitive nature of the industry, fast fashion uses the timeframe from design conception until product delivery to maintain an advantage; fast fashion typically designs a new collection and has the finished garments in retail stores within four months or less. To achieve this extremely short timeframe, PLM systems allow retailers to streamline communication, enhance shipping solutions, and develop effective collaboration throughout their entire supply chain, enabling retailers to respond rapidly to changing consumer tastes and provide goods with consistent quality and style.

The overall impact of utilizing PLM systems on the fashion industry is enormous: they have decreased the unit price to produce garments and improved production processes, both of which have created affordable clothing for end-users, as well as positively affect job creation and economic growth within the developing world. However, because these networks are based on global supply chains, many of them also possess significant vulnerabilities due to their international nature together with the inherent instability within global supply chains. As demonstrated by the COVID-19 pandemic, disruptions at one site within the global production supply chain can adversely affect all nodes of that supply chain.

Many companies have decided to invest more heavily in digital tools to improve operational stability and enhance visibility. By providing greater insight into the production process, PLMs enable companies to better understand and manage their exposure to risk and respond more quickly and effectively. PLMs also promote greater transparency—an issue facing increasing regulatory scrutiny as global awareness of sustainability grows.

As differences in costs and capabilities continue to shape international trade patterns, these developments, combined with digital supply chains, will be key to the future of the apparel industry. By enabling companies to operate across borders while maintaining control over complex global production systems, PLMs have become an integral part of the modern structure of the fashion industry and the global economy as a whole.
