What Is Stakeholder Engagement in DMA? The Pairwise Comparison Method
Under the Corporate Sustainability Reporting Directive (CSRD), conducting a Double Materiality Assessment (DMA) is the first step toward compliance. But a DMA is not a desk exercise for your sustainability manager. It legally requires stakeholder engagement—consulting employees, customers, suppliers, investors, and local communities to identify your company's impacts, risks, and opportunities (IROs).
However, traditional methods of stakeholder consultation often lead to a common trap: rating fatigue and priority dilution.
This article details why conventional survey tools fail and explains how ExecutESG's Pairwise Comparison Method solves stakeholder misalignment.
The Failure of the Likert Scale (The 5/5 Trap)
Most sustainability consultants use standard survey tools (like Google Forms or Typeform) and ask stakeholders to rate the importance of various ESG topics on a 1-to-5 scale (Likert Scale).
This leads to a predictable outcome:
- The Employee rates health and safety as 5/5.
- The Customer rates product safety as 5/5.
- The Investor rates climate change risk as 5/5.
- The Local NGO rates biodiversity as 5/5.
When everything is a priority, nothing is. You end up with a flat materiality matrix where 20+ topics cross the materiality threshold, forcing your company to report on hundreds of data points that are not actually strategic.
What is the Pairwise Comparison Method?
To resolve rating dilution, ExecutESG uses the Analytic Hierarchy Process (AHP), commonly known as Pairwise Comparison.
Instead of asking stakeholders to rate 30 topics individually, pairwise comparison presents them with two topics at a time and asks a simple question:
- "Which of these two topics has a more significant impact on the environment, and by how much?"
- "Which of these two risks has a greater potential financial impact on our operations?"
By forcing stakeholders to make a relative choice between two options, the system uses matrix mathematics to calculate absolute weights and priority scores for each topic.
Why Pairwise Comparison Wins for SMEs
1. Eliminates Rating Fatigue
Instead of reviewing a massive grid of 30 compliance statements, stakeholders respond to quick, binary comparison prompts. This keeps engagement high and yields cleaner data.
2. Resolves Scoring Variance
Different stakeholders define "High Impact" differently. A rating of "4" to a CFO might mean a €10M risk, whereas to an HR manager it might mean a minor policy change. Pairwise comparison bypasses scale bias by measuring relative preference, which is mathematically standardized.
3. Delivers a Clear Materiality Threshold
The math behind pairwise comparison naturally spreads the final scores. This creates a clear gap between material and non-material topics, allowing your team to defend your reporting boundaries to auditors with scientific confidence.
Standardizing Your Stakeholder Engagement
Using ExecutESG, you can launch automated pairwise surveys directly to your stakeholder groups. The platform aggregates the matrix data, calculates the geometric mean of responses to resolve variance, and automatically maps the results onto your final Double Materiality Matrix.
