What is Supplier Segmentation? Types, Matrix, Best Practices

Supplier segmentation is a strategic process that procurement professionals and supply chain managers use to categorize suppliers by their importance, risk, and value to the business. Why? Because businesses rely on suppliers for everything (from raw materials to specialist components) and not all suppliers should be treated the same.

If a specific supplier fails to deliver the entire procurement pipeline can come to a standstill. Spending too much time managing low impact suppliers is a waste of resources. That’s why supplier segmentation is key. It helps companies focus on strategic suppliers, optimize supplier performance, reduce supply risk, and improve overall supply chain management.

This article will look at the basics of supplier segmentation process, why is supplier segmentation important, and how businesses can use segmentation models and best practices to be more efficient. We’ll also cover supplier relationship management, supplier risk, and how procurement professionals can build stronger supplier relationships.

What is Supplier Segmentation?

Supplier segmentation is the process of categorizing suppliers based on risk, supplier importance, and performance to manage them better. Prioritizing strategic suppliers while ensuring business continuity and cost savings is the goal.

Companies can also customize their supplier management approach, prioritize resource allocation, and focus on supplier performance management. By having a defined supplier segmentation model it helps organizations to identify strategic suppliers, reduce supplier risk, and create a stable supplier ecosystem.

Effective supplier segmentation means procurement teams are working on key suppliers while being flexible on low priority suppliers.

Benefits of Supplier Segmentation

Supplier segmentation allows companies to make wiser, more strategic decisions. These are the main advantages of segmenting your suppliers in order to stimulate more robust relationships, minimize risk, and optimize supply chain performance.

Improving Supplier Relationships – You can determine your most important supplier relationships and design custom engagement strategies by segmenting suppliers. Your most important suppliers receive the attention they deserve so your supply chain is stronger and more reliable.

Reducing Supply Risk – You can see risk factors and apply supplier risk management with this segmentation. By mapping your bottleneck suppliers, you can respond before supply chain disruptions.

Maximizing Supply Chain Effectiveness – Segmentation implies procurement activities are focused on your business goals. You can target high value suppliers and streamline processes for secondary suppliers.

Enhancing Resource Allocation – Segmentation enables you to rank suppliers according to their value to your business. Your purchasing departments can concentrate on the suppliers that are most important to your organization.

Business Continuity – You are able to create a constant supply chain and minimize the risk of surprise disruption if you constantly screen and categorize your suppliers in terms of performance and dependability.

4 Types of Supplier Segmentation

Supplier segmentation helps businesses categorize suppliers based on key factors like strategic importance, performance, and location. This process ensures efficient management and risk mitigation.

Strategic Suppliers

Strategic suppliers are those that deliver products or services with a high impact on the organization’s competitive advantage, innovation, and operational continuity. These suppliers are typically few in number but represent significant business value.

Examples:

A sole-source manufacturer of a critical component, or a technology provider integral to your product or service.

Key Characteristics:

• High switching costs or long lead times to replace
• Direct influence on product quality, brand reputation, or customer satisfaction
• Often involved in joint R&D, co-development, or long-term innovation projects

Management Strategy:

• Build strong, long-term relationships
• Maintain executive-level engagement and alignment
• Collaborate on strategic goals, risk management, and innovation pipelines
• Regular performance reviews with shared KPIs and continuous improvement initiatives

Preferred Suppliers

Preferred suppliers are reliable partners that consistently meet performance expectations and may have earned a favored status through quality, cost-efficiency, and ease of doing business. They are important to daily operations, but not irreplaceable.

Examples:

A regional logistics provider with excellent on-time delivery, or a consistent supplier of standardized parts.

Key Characteristics:

• Proven track record of quality and service
• Competitive pricing and delivery terms
• Flexibility to meet fluctuating demand

Management Strategy:

• Use for regular procurement needs with simplified procurement processes
• Maintain periodic reviews to ensure continued alignment with business goals
• May be given priority access to new business or contract extensions
• Encourage cost-saving and process improvement proposals

Transactional Suppliers

These suppliers provide non-critical, commoditized, or easily substitutable goods and services. The relationship is generally low-touch, and the emphasis is on cost control, availability, and speed rather than partnership.

Examples:

Office supplies vendors, janitorial services, or bulk packaging material providers.

Key Characteristics:

• Low value or low business risk
• High availability and competition in the market
• Minimal customization or differentiation

Management Strategy:

• Focus on price, availability, and ease of procurement
• Use automated procurement processes (e.g., catalogs, e-procurement)
• Rotate suppliers frequently or run competitive tenders
• Minimal relationship management unless problems arise

Tactical Suppliers

Tactical suppliers are situationally important—they may be vital for specific projects or short-term needs but don’t necessarily contribute to long-term strategy. They might provide specialized skills or materials needed intermittently.

Examples:

Contractors for a specific construction project, or niche raw material providers used occasionally.

Key Characteristics:

• Mid-level spend and complexity
• Risk may vary depending on project scope
• Limited strategic value but still require some oversight

Management Strategy:

• Monitor performance closely during project periods
• Maintain a pool of pre-qualified vendors
• Assess whether any tactical suppliers should be developed into strategic or preferred suppliers over time
• Evaluate potential risks or bottlenecks in advance of project kick-offs

Steps in Segmenting Suppliers

To segment suppliers effectively, you need to follow a structured process that includes data analysis, risk assessment, and continuous monitoring.

1. Objectives and Criteria

First you need to define your objectives and criteria. Whatever supplier segmentation model you choose (cost, risk, or strategic importance) you need to determine which one fits your business needs. If you have clear supplier management goals you can make sure your segmentation is aligned to long term growth.

2. Data Collection and Analysis

Next is data collection and analysis. Procurement professionals need to gather qualitative data, conduct risk assessments, and evaluate supplier performance. This step involves analyzing key relationships, delivery performance, and risk factors to ensure supplier categorization is accurate.

3. Supplier Segmentation Models

Then you apply a segmentation model (Kraljic Matrix) to group suppliers by strategic importance and risk. This allows you to prioritize suppliers, manage supplier risk, and optimize procurement strategies.

4. Implement and Monitor

Finally implement and monitor to ensure supplier categories stay accurate. Review supplier performance, adjust your segmentation strategy, and refine your supplier relationship management practices to maintain procurement chain resilience and efficiency.

The Supplier Segmentation Matrix

The Kraljic Matrix is a popular model that classifies suppliers in terms of profit and risk impacts. Strategic suppliers consist of high-profit impact and high supply risk and need strong relations and risk handling. Bottleneck suppliers have high supply risk but low profit impact and need monitoring and contingency planning.

Leverage suppliers have high profit influence with low risk, enabling firms to negotiate favorably. Non-critical suppliers are low influence and low risk, best addressed through streamlined purchase. The pyramid of suppliers puts strategic and bottleneck suppliers at the pinnacle, requiring most effort in management, with secondary suppliers falling at the bottom, needing less effort in management.

Managing Critical and Bottleneck Suppliers

Strategic and bottleneck suppliers need proactive management to avoid supply disruptions. Businesses should build relationships with suppliers via regular communication and long-term contracts and monitor performance and determine risks using the management software.

To reduce in disruptions, firms ought to perform risk analyses and develop alternative sourcing strategies. Although cost effectiveness is essential, it is vital to prioritize supplier reliability to ensure continuity and resilience.

Managing Non-Critical Suppliers

While non-critical suppliers need less attention, companies must still maximize procurement by streamlining processes and applying supplier segmentation software to monitor performance. Periodic review of models ensures that suppliers are properly categorized as business demands change. A secondary supplier today may become critical in the future, so routine reassessment is important to an effective segmentation strategy.

Performance and Risk Management

Supplier segmentation helps with supplier performance management by being efficient, risk averse and decision making. Companies should balance quantitative measures like cost and lead time with qualitative judgements like trust and cooperation.

Prioritizing relationship management increases resilience, business continuity, and innovation. A structured segmentation strategy helps companies manage risk, streamline procurement, and build a more trusted supply chain.

Best Practices in Supplier Segmentation

Every company’s procurement process, relationships, and supply chain resilience can be all streamlined with a good supplier segmentation. So here are some best practices to follow: 

1. Apply the Pareto Principle – It’s basically  a principle or an 80/20 rule that states that 80% of a company’s spend is on 20% of its supplier. It just means companies should bring focus on managing strategic and core suppliers who have more impact on business operations for maximum efficiency, better risk management, and cost-savings. 
2. Use Data Analysis – Data-driven approach is the core of supplier segmentation. There’s quantitative data and qualitative data about suppliers. Quantitative is like the cost, delivery performance, and volume of orders while qualitative is more on reliability, innovation, and strength of relationship. Companies should gather and analyze both with supplier management software and high-level analytics so they can uncover the most important factors that affects suppliers’ performance and reconfigure their model based on it. 
3. Execute a Segmentation Strategy – Possessing an explicit and considered supplier segmentation strategy is the most critical factor in dealing with a differentiated supplier base. That includes categorizing suppliers according to strategic significance, risk, and impact on cost. Executed well, this allows procurement teams to prioritize efforts where they are needed most. It is also necessary to ensure the segmentation model is clearly understood—not only by the procurement team, but by key stakeholders and even the suppliers themselves. A robust segmentation method enables organizations to allocate resources better, simplify processes, and forge improved supplier relationships.
4. Review and Update Supplier Segments Periodically – Supplier segmentation is not a "set it and forget it" activity. Business requirements change, markets change, and suppliers' performance may shift—so the segmentation model must keep up. Periodic reviews ensure you're still categorizing suppliers correctly according to their current performance, risk level, and strategic importance. Keeping the model current allows companies to remain responsive, react rapidly to change, and continue making informed decisions.

Through implementing these practices, companies can improve their relationships with suppliers, build a more resilient supply chain, and enhance efficiency as well as risk management in the long term.

Supplier Segmentation Challenges

Supplier segmentation is a great tool for supplier management and risk mitigation but it’s not without challenges. Companies are usually faced with organizational resistance, data constraints, and technology issues. Here’s how to overcome them:

Resistance to Change

Perhaps the biggest obstacle to successful supplier segmentation is internal employee resistance or supplier pushback. Procurement teams may be hesitant to change their supplier management processes, thinking it will be more complicated or more work. Suppliers will also resist being segmented in ways that reduce their contract potential.

Solution: Companies should educate internal teams on the benefits of segmentation and how it will make them more efficient. A collaborative process with suppliers will also help to alleviate fears and get everyone on the same page.

Lack of Data

Effective supplier performance management calls for complete and accurate records of costs, lead time, quality and risk factors. Unfortunately, most companies operate with fragmented data or incomplete records, which makes it challenging to classify the suppliers according to strategic significance.

Solution: Business firms must make an investment in a management system that integrates live data and actionable insights. Defining standard practices for data collection (e.g., monitoring service quality, delivery performance, and contract adherence) guarantees that decisions regarding segmentation will be based on factual, recent information.

Inadequate Technology

Without the right tools, managing models and conducting risk analyses can be inefficient and time-consuming. Companies using manual spreadsheets or legacy software might find it difficult to classify suppliers.

Solution: Implementing automated supplier management solutions enables firms to automate the process of segmentation, perform risk assessments, and track relationships easily. Technologies such as AI-powered analytics can assist firms in enhancing supplier risk management, supply chain segmentation, and procurement processes.

By solving these issues with a strategic solution, businesses can achieve new cost-saving potential, foster more robust relationships, and establish a more robust supply chain.

Conclusion

Supplier segmentation is a key tool for companies who want to improve supplier management, reduce risk, and maintain supply chain resilience. By segmenting suppliers by strategic importance, performance and risk you can improve procurement processes, focus on key suppliers, and reduce the risk of supply network disruption.

By the right segmentation strategy and regular performance management you can maintain better supplier relationships, simplify operations, and be more competitive.
