Supplier Diversity: Definition, Benefits & Important Resources

Supplier diversity is a practice that involves companies intentionally cultivating supply chains that include businesses owned by historically underrepresented groups. This can include a range of demographic groups, including businesses owned by women, racial and ethnic minorities, veterans, LGBTQ+ individuals, and those living with disabilities.

This is a vital contributor to a more equitable business landscape, alongside offering companies some distinct advantages. Our article takes a closer look at the concept, why it matters for global businesses, and what the practical approaches to locating and working with diverse suppliers are.

What Is Supplier Diversity?

Diversity in suppliers refers to company owners proactively engaging with supply chain businesses owned by people representing diverse demographics. Suppliers must be at least 51% owned and operated by individuals representing historically underrepresented groups.

Typical demographics include:

• Racial or ethnic minority-owned businesses
• Women-owned businesses
• Veteran-owned businesses
• LGBTQ+ owned businesses
• Businesses owned by people with disabilities 

This concept has its roots in the U.S. civil rights movement, applied initially to public sector contracts, before being adopted in corporate procurement. These programs are also often divided into direct and indirect categories. Direct diversity involves procuring goods and services directly from diverse-owned businesses. The indirect method is about working with non-diverse suppliers that utilize diverse subcontractors or vendors.

Why Supplier Diversity Matters in Today’s Economy

Diversity is driven by the need to promote equality and inclusion, helping address the systemic barriers faced by entrepreneurs from underrepresented demographics. This redistribution of opportunities helps to create a stronger business landscape.

It is also central to corporate social responsibility (CSR) and Environmental, Social, and Governance (ESG) principles. Investors, regulators, and consumers are increasingly vigilant about the companies’ social impact. Diversifying suppliers is one of the methods used to demonstrate a proactive commitment to responsible business. It’s also especially relevant for multinational and global operations, as inclusivity is swiftly becoming the norm worldwide.

Beyond this, businesses find supply chain diversification boosts resilience. It reduces dependency on a narrow set of vendors that all feature similar risks and approaches to business. This enables companies to be more operationally agile.

Key Benefits of Supplier Diversity

The main benefits of proactive supplier diversification include:

• Innovation – Supplier diversification offers access to fresh ideas, different market perspectives, and more innovative approaches to strategy.
• Stronger relationships – Connections with more diverse suppliers often translate to stronger relationships with local communities, industry partners, and socially-conscious stakeholders.
• Operational resilience – Diverse networks of suppliers enable greater agility, which may result in more robust risk management and better disruption responsiveness. This can be particularly useful for just-in-time inventory management.
• Goal alignment – Diversity helps maintain alignment with inclusivity targets and standards set by public and private sector clients or regulatory bodies.
• Reputational boost – Authentic engagement with programs can improve social impact credentials and brand reputation.

Challenges in Implementing Supplier Diversity Programs

Implementing effective supplier diversification protocols can be challenging. One hurdle is it can be difficult to identify and verify suppliers that genuinely meet diversity standards. Not to mention that small, diverse suppliers often have limited access to corporate procurement pipelines, particularly those without the capacity or technical infrastructure to bid for large contracts.

Internally, companies can also face resistance from staff who are unfamiliar with the value and importance of these programs. Alternatively, there can be a lack of clarity in procurement processes that results in ineffective or inconsistent engagement. This can also be exacerbated by companies failing to implement solid data tracking and accountability systems and, therefore, struggle to communicate true impact to stakeholders. 

Identifying and Finding Diverse Suppliers

There are various methods for engaging with diverse suppliers. Firstly, national and international certification bodies—such as the National Minority Supplier Development Council (NMSDC), the Women’s Business Enterprise National Council (WBENC), and Disability:IN in the U.S.—maintain lists of qualified businesses.

Additionally, recognized diverse supplier networks and databases can streamline identification. Many database platforms enable companies to filter by specific certifications, regions, and industries. It can also be effective to partner with regional chambers of commerce and business councils dedicated to minority businesses, as they can facilitate introductions. There is also an increasing number of supplier matchmaking events and outreach programs that connect corporate procurement representatives with diverse suppliers.

Certification and Verification of Diverse Suppliers

Certification and verification help confirm to businesses that they’re genuinely engaging in an impactful way, while also providing credible reference for compliance reporting protocols.

There are differing certifying bodies, depending on demographic focus and region. For instance, the Canadian Aboriginal and Minority Supplier Council (CAMSC) or Minority Supplier Development U.K. (MSDUK) both provide region-specific certifications and up-to-date databases. Globally, WeConnect International helps certify women-owned enterprises in various jurisdictions.

While self-certification—in which suppliers identify themselves as minority-owned—is possible, third-party certification by dedicated agencies provides more objective eligibility verification. The third-party approach is also likely to lend credibility to reporting.

How to Build a Supplier Diversity Program

Building an effective diversity program begins with securing leadership buy-in and establishing an approach that aligns with corporate values. Backing from executives can ensure procurement initiatives gain the resources and attention they need to thrive.

Maintaining an authentic program also requires internal accountability. Appointing a supplier diversification manager or team is key to this. They can also set clear strategic goals and measurement criteria to drive programs and identify improvements.

Businesses must build diversity standards into procurement protocols, too. This includes embedding diversity criteria into requests for proposals (RFPs), vendor evaluations, and other sourcing processes.

Beyond this, companies should establish onboarding, training, and development processes for diverse vendors. A business consultant service can also be a useful resource here. A commitment to offering support related to engaging with corporations and meeting corporate standards is a valuable investment in community entrepreneurship.

Measuring the Impact of Supplier Diversity

Establishing the success of diversity programs begins with quantitative data. Some of the basic key performance indicators (KPIs) companies use include the percentage of total procurement spend dedicated to diverse suppliers, supplier retention rates over time, and the volume of contracts issued.

These metrics are often tracked in real time through the use of internal supplier dashboards. This gives companies greater visibility so they can make adjustments where needed. Many corporations also include these metrics in annual ESG and CSR reports to boost accountability.

Beyond the numeric data, qualitative outcomes are also useful. Gaining accounts of success stories, feedback on community engagement, and qualitative surveys with suppliers can highlight not only positive impact, but also where meaningful improvements in approach should be made.

Global Considerations for Supplier Diversity

One of the challenges of applying supplier diversification globally is that there are often differing definitions or norms between jurisdictions. For instance, U.S.-centric frameworks that largely focus on race and ethnicity may not be directly portable to subsidiaries in Australia, where there can be more emphasis on indigenous ownership and social enterprise. Furthermore, some jurisdictions have stricter data privacy laws than others. As a result, companies must work with local experts to understand the norms and frameworks that apply. This may also influence considerations of Greenfield vs. acquisition foreign investment, as acquired companies may already have reliable protocols in place. In addition, engaging with local certification bodies and partnering with community organizations in each operational jurisdiction can be key to successful inclusive procurement strategies abroad.
