The business case for diversity, equity, and inclusion (DEI) starts with a practical question: how can an organization give people a fair opportunity to contribute while improving the way it works?

Research published in 2026 offers useful evidence, but it does not support a guaranteed financial return from every initiative carrying the DEI label. Some findings connect diversity and inclusion with stronger financial performance. Others show mixed results and highlight the importance of implementation.

For employers, the challenge is to identify specific workplace problems, choose appropriate practices, and evaluate what changes.

Does DEI Improve Financial Performance?

A 2026 study published in Global Business Review examined 567 publicly listed European non-financial companies using data from 2014 through 2024.

The authors found that stronger diversity and inclusion ratings were associated with better financial performance. Employee development was the main contributor to that relationship, reflecting companies’ commitment and effectiveness in training and developing their workforce (Pellegrino et al., 2026).

That finding supports taking employee development seriously. However, an association does not establish that introducing a particular DEI program will cause profits to rise. The study also concerns European listed companies, so its results should not automatically be applied to every employer.

Other research adds important context.

Son et al. (2026) examined DEI in operations and supply chain management, combining employee reviews and company financial data with interviews involving 10 experienced DEI leaders and practitioners.

Their evidence on DEI and company performance was mixed. Interviews identified potential benefits for engagement and job satisfaction, alongside concerns about initiatives that lack substance, alienate employees, or introduce significant short-term costs.

Together, these studies suggest that employers should examine what an initiative actually does before making claims about its business value.

Why Inclusion Matters Alongside Diversity

Recruiting people with different backgrounds is only part of the work. Employers also need to consider how people participate, receive recognition, and access development opportunities.

In a 2026 commentary, management scholar Brooke A. Gazdag argues that organizations should focus on the working conditions that allow different perspectives to contribute. Her recommendations include examining everyday practices and testing whether changes improve inclusion (Gazdag, 2026).

For an employer, useful questions include:

• Do employees understand how development opportunities are allocated?

• Can team members contribute ideas through more than one format?

• Do managers explain how work is evaluated and recognized?

• Are employees able to identify barriers and suggest improvements?

These are practical review questions, not a validated assessment tool. They offer a starting point for examining specific processes.

Fair treatment also has value as an organizational principle. Employers can explain that commitment while separately evaluating the costs and outcomes of individual initiatives.

Build a Business Case Around a Specific Problem

A July 2026 report from The Conference Board draws on a survey of 152 U.S. business leaders. Its public summary reports widespread support for diversity and inclusion, alongside difficulty connecting that support to measurable productivity gains. It identifies gaps in leadership alignment, infrastructure, and execution (Schweyer & Maloof, 2026).

A useful response is to make the proposed change concrete.

For example, an employer concerned about access to training could document eligibility requirements, explain how employees apply, and establish consistent selection criteria.

Before introducing the change, the organization should define:

1. The problem: What evidence suggests that the current process needs improvement?

2. The action: What will change, who will manage it, and what will it cost?

3. The intended outcome: What would meaningful improvement look like?

4. The review method: What information will help determine whether the change worked?

This approach gives leaders something specific to evaluate and employees a clearer explanation of the initiative’s purpose.

Measure Outcomes Carefully

Choose measures that match the activity.

For a development initiative, possible measures include participation among eligible employees, completion, demonstrated skill growth, and subsequent opportunities to apply those skills.

For a recruitment initiative, employers might examine application completion, the proportion of applicants meeting job requirements, and candidate feedback.

These are suggested measures, not promised outcomes.

Record a baseline and review results over a defined period. Include costs and employee feedback. Consider other changes—such as pay adjustments, management turnover, or labor-market conditions—that could affect the results.

A change that follows an initiative is not automatically a change caused by it.

Start With Clearer Hiring Communication

Job descriptions offer a practical starting point for reviewing how an organization communicates opportunity.

Examine whether each requirement reflects the work, whether essential and preferred qualifications are clearly distinguished, and whether applicants can understand what success in the role involves.
