What Is Supply Chain Management and Why Is It Important?

Supply Chain

Many of today’s organizations recognize the key role their supply chains play in their ability to garner a competitive advantage in the marketplace. Perhaps that helps account for the anticipated 11.2% growth for the global supply chain management market between 2020 and 2027, as recently reported by Research and Markets, a global provider of market data.

So, what is supply chain management and why is it so important? To answer that question, it’s useful to look at how the supply chain process works. It also helps to examine the components of supply chain management, as well as trends and careers in the field. 

What Is Supply Chain Management?

Almost every product in the marketplace appeared there as the result of various entities working together in a supply chain. Supply chain management deals with how businesses turn raw materials into finished products, and then transport and distribute those products to consumers.   

Supply chains are systems that link organizations to their suppliers, allowing them to produce and distribute goods and products. These systems organize various activities, resources, and information. They also serve as networks that connect:

To offer a simple illustration of a supply chain, consider the journey of how roses make their way from a florist to customers — that is, to the end of the supply chain. First, a flower grower or floriculturist plants seeds and grows the roses. A business buys the floriculturist’s roses, transports them to a warehouse, and sells them to a florist. That florist then sells them to customers. 

Supply chain management works to design and implement the most efficient and cost-effective supply chain process possible. Companies understand that when a single link in the supply chain breaks, it costs valuable time and money. 

As such, supply chain management uses various strategies to centrally control internal and vendor inventories, internal production, distribution, and sales to cut unnecessary expenses. Streamlining supply chain activities also results in faster production. This allows businesses to better compete and in turn, creates value for customers.   

Accurate information about a supply chain saves companies money. It helps manufacturers and retailers produce and transport only what they can sell. This eliminates the unnecessary expenses associated with producing, insuring, and shipping inventory a company can’t sell. 

Components of Supply Chain Management

A careful review of the components of supply chain management, also referred to as the supply chain management steps, can further illuminate what supply chain management is and why it is important. 


Before the supply chain begins, organizations need well-designed strategies to effectively manage each stage of the process. They develop plans to determine the overall costs, profits, and required manpower to get the job done. Supply chain management experts weigh the pros and cons of various supply chain methods and develop a blueprint for how to proceed.

They also use a set of metrics to measure how efficiently a supply chain meets organizational goals and customer needs. 

Examples of these metrics include the following. 

Cash-to-Cash Time Cycle

This metric allows organizations to calculate the time needed to turn their resources into money that can move in and out of the business. The metric uses three primary ratios:

A short cash-to-cash time cycle means organizations have less of their money tied up, allowing them to operate with greater agility. 

Perfect Order Rate

A perfect order rate refers to how frequently an organization delivers orders without inaccuracies, delays, or other issues. Awareness of this metric allows organizations to hone in on problem areas that affect customer retention and satisfaction.

Inventory-to-Sales Ratio

The inventory-to-sales ratio measures how much inventory is for sale vs. how much is sold. This helps organizations maintain balanced inventories that are neither too high nor too low. 


The second supply chain management step is sourcing. Organizations rely on suppliers to provide the different raw materials to make their products. Finding suitable quality materials at good price points makes it possible for a business to create quality, offer competitively priced products, as well as build a strong reputation in the market. 

Sourcing also involves choosing suppliers who provide services to run a particular component of the business. For example, a hotel chain might need pool maintenance services, or manufacturers may need equipment maintenance.

After choosing suppliers, organizations need to manage these relationships and monitor processes — such as ordering, receiving inventory management, and payment authorizations — to ensure they meet certain standards. They also need to build trust and solid communication with suppliers. The more trust and better the communication, the more likely a company will receive improved service and preferential terms. 


Manufacturing is the stage of supply chain management in which companies take raw material — human or natural resources — and turn it into goods or services. Depending on customer needs and business goals, organizations determine the most suitable production process. 

Companies that produce goods or services in large numbers, such as headphones, light bulbs, or processed foods for example, will likely choose a mass production model. Companies that manufacture items according to customers' preferences and individual demands will usually select different customized production processes.     

Manufacturing involves assembling, quality testing, and packing for delivery. To ensure products meet specified standards and manufacturing efficiency, supply chain professionals decide how to best perform the following tasks.


Delivery, sometimes referred to as logistics, includes transportation and warehousing. This component of supply chain management involves:

Specific elements of logistics include transportation management, freight audits, and order management.

Transportation Management

Organizations rely on vehicles, whether trucks, ships, trains, or airplanes, to ship their goods. Often, they outsource delivery to companies that specialize in it. Whether handled in-house or by contractors, delivery requires transportation management — the use of techniques that optimize the movement of goods between warehouses and retailers. Techniques include planning optimal delivery routes and shipping loads.

Freight Audits

To gain insights into the efficiency of the delivery process and save money, logistics professionals conduct freight audits. These audits analyze freight bills (invoices to shippers) to identify mistakes such as overbilling. They also can turn up information regarding long-standing issues that need to be resolved.

Order Management

Order management involves a systematic approach to taking, tracking, and completing customer orders. It starts when customers place orders and ends when they receive the goods or services. Streamlining this process allows companies to avoid being overwhelmed with orders.

Effective order management helps companies:


Another crucial supply chain management step involves creating a smooth process for customers to return purchased products. While organizations may have robust quality control programs, defective or damaged products that customers want to return are inevitable. Equipment can fail. Malfunctioning products can slip through. Other times, customers can just change their minds and want to return perfectly good products.

Whatever the case, organizations need responsive networks that smoothly manage returns. This protects a company’s reputation and demonstrates goodwill. 

The return process involves:

To really understand what supply chain management is, its critical to consider innovations and disruptors that are transforming the field. This calls for a discussion of supply chain analytics and other trends that continue to influence the industry.

Supply Chain Analytics

Supply chains produce huge amounts of data, which, if properly leveraged, can empower organizations to make faster, more strategic decisions. Many of todays supply chain leaders recognize the need to harness the power of data to boost their effectiveness.

Supply chain analytics involves taking the information generated in the supply chain processes and using it to find patterns that offer insights into a variety of issues.

Operational Visibility

Operational visibility refers to an organizations ability to clearly see how its operations are running. It involves monitoring various supply chain activities to understand their performance. One of the greatest challenges arising in supply chain management relates to operational visibility.

Without it, supply chain professionals struggle to identify key metrics they need to act on. As a result, they often don’t discover problems until they hear about them from unsatisfied customers. Data analytics, specifically descriptive analytics, allow supply chain professionals to gather key insights about their past performance.

This helps them gain a more complete understanding of the strengths and weaknesses across the supply chain. It also enables them to notice trends that can inform more strategic decision making. 

Potential Disruptions

The complexity of supply chains makes them vulnerable to disruptions and risks. However, by examining current and past patterns in supply chain data, supply chain analytics can help predict which patterns may appear again.

These forecasts can help organizations prepare for disruptions, such as shortages in raw materials, price surges, or weakness in market demand. In fact, one of the biggest issues in supply chain management involves effectively handling fluctuating customer demands. Supply chain analytics often helps organizations anticipate such problems, giving them a better chance at lessening potentially negative impacts.

Optimal Supply Chain Operations

To stay competitive, organizations strive for continuous improvement in their supply chains. They need to solve problems and find opportunities for collaboration that optimize the processes in all their supply chain components.

Supply chain analytics looks at possible scenarios, past and current performance, and available resources, and then points to strategic methods for moving forward. This can help organizations form critical partnerships within the supply chain that speed up operations, improve alignment between different entities, and lower costs.   

In addition to embracing data analytics, the supply chain industry is also adopting other innovations that are revolutionizing business. Artificial intelligence (AI) technology, for example, can significantly streamline supply chain processes.

AI in Supply Chain Management

Artificial intelligence (AI) uses computer programs to simulate human thinking to solve problems. By applying AI, organizations can optimize their ability to identify and remove inefficiencies in their supply chain, improve operational visibility, increase worker safety, and more.

As noted, the supply chain generates a tremendous amount of data. That data comes from places such as:

With AI, supply chain professionals can use data to perform numerous tasks that save money and increase output. For example, AI can predict maintenance needs with incredible accuracy. AI also analyzes data from the Internet of Things (IoT), and identifies innovative solutions that optimize everything from scheduling to invoicing.

Through its automated intelligence, AI learns and adjusts as new information becomes available, tailoring recommendations to each individual situation.

COVID’s Disruption to the Supply Chain Industry

COVID-19 brought many important lessons to the supply chain industry. According to Resilinc's 2020 EventWatch Report, the industry experienced 14% more disruptions in the first nine months of 2020 than it experienced in the entire year of 2019. More than half of these disruptions were serious enough to threaten the viability of suppliers.

The pandemic exposed many supply chain vulnerabilities, such as the risks of relying heavily on global suppliers for raw materials. Along with exposing vulnerabilities, the pandemic put a spotlight on the need to rethink the current global supply chain model.

Today’s supply chain industry needs alternatives to linear supply chain models. It needs a more dynamic model that breaks down divisions between teams across the supply chain, allows for a greater flow of information, and harnesses the abilities of analytics. Such a transformation will allow the supply chain industry to better absorb shocks ranging from global pandemics to trade wars.

Supply Chain Management Careers

With new insight into what supply chain management is and why it is important, it’s time to look at some supply chain management careers. The expanding supply chain management industry offers numerous job opportunities.


Logisticians oversee the entire lifecycle of a product, meaning they manage all the steps it takes to acquire raw materials, turn them into products, and then distribute those products.
