Sedex + Ulula Pilot Program: Combining worker voice technology and SMETA to drive audit efficiency, issue detection and improvement

Written by Ulula

Pilot project context and background

Sedex and Ulula collaborated on a pilot project to see how the deployment of worker voice surveys before onsite SMETA audits could improve the execution of an audit and its output. Beginning in March 2022 and running until July, the pilot’s primary objective was to amplify workers’ voices while providing worker voice data to auditors to inform decision making.

By joining forces, Sedex and Ulula defined a multi-stakeholder rollout plan to enable auditors, buyers and suppliers to collaborate and engage in a continuous improvement process that is aligned with SMETA methodology and help reduce early survey fatigue.

Pilot objective

The purpose of adjoining Ulula’s worker voice with SMETA audits was three-fold:

  1. Provide site-level worker voice data to help auditors prepare for an audit before they arrived on site, allowing them to pin-point and address recurrent issues quickly and accurately.
  2. Increase engagement with workers within the SMETA audit process by hearing from more workers through surveys and audit interviews, removing language barriers, and providing an anonymous feedback channel for workers to discreetly respond to survey questions without fear of reprisal.
  3. Provide buyers and suppliers with additional information to improve their understanding of workplace risks and inform how they might improve their workers’ well-being and satisfaction.

In addition to the goals of the current project, Sedex and Ulula wanted to build on existing lessons learned from the Sedex Direct Worker Reporting project to improve how digital worker voice surveys can complement the SMETA audit methodology and ETI base code.

The pilot achieved a high level of interest and participation from all engaged stakeholders. With 10 buyers, 32 suppliers, and more than 2,400 workers involved in the project, the pilot successfully captured an impressive amount of worker voice data from food, agriculture, and apparel sectors around the world.

Workplaces participating in the project included sites in Thailand, Mexico, China, and Australia, and the surveys were deployed in seven local languages including English, Spanish, Mandarin, Burmese, Tetun, Bislama, and Thai. The surveys were accessible to workers on the Internet via QR code and URL, and via Interactive Voice Response (IVR) using voice call.

Ulula’s Role

Ulula was uniquely situated to work with Sedex to achieve the project’s positive outcomes, providing both its robust and scalable worker feedback technology as well as its extensive experience in designing social compliance surveys and integrating with social audits at scale. Ulula’s team socialized the program with stakeholders, developed training materials, designed the survey instrument and advised program participants throughout the onboarding process.

Benefits of the Ulula + Sedex joint model

The key benefit of the pilot project was its ability to elevate worker voices and their workplace concerns by giving buyers, suppliers and audit firms a keen awareness of employee well-being throughout their work sites.

“There’s benefit in understanding answers on worker surveys and making comparisons with SMETA report  and comments from auditors. The audit can help to identify misunderstandings from workers on the questions.“Hershey’s


A number of key results emerged from the data collected during the pilot’s deployment:

  • Post-survey audits in participating sites were found to be better targeted, more efficient, and of a higher quality than previous on-site audits
  • Auditors were better able to focus on targeted data and emerging trends within the workplace that were captured in the worker voice surveys.
  • Pre-audit surveys also improved the detection of issues within the workplace and the stakeholders’ understanding of site risks and employee well-being
  • Suppliers and buyers were better equipped to address common issues and where to direct their efforts.
  • Workers have a better understanding of their rights in relation to topics covered in the ETI Base Code

Some of the most important takeaways from the project have come from the key stakeholders and their experiences with the pilot. Here is some of what we learned from participating groups:

“The results of the survey in advance highlighted point[s] which I should focus on during the onsite audit. Besides, the results were helpful for me to allocate more time on those high risk area.” – SGS

Auditor facing:

Overall, auditors found that the Ulula + Sedex pilot was a more streamlined way of audit planning and preparation than previous models. Pre-audit surveys allowed auditors to determine specific areas of concern where a deep dive investigation would be necessary. Running worker surveys over several days ensured that workers had time and opportunity to participate and enabled feedback collection from a higher volume of people. Insights gathered from the surveys informed management of how to better allocate resources within the workplace. Finally, auditors shared that it was important to offer an independent third-party platform for workers to voice their concerns confidentially and without fear.

Buyer and supplier facing:

Buyers found that the project helped start conversations and build strong, trusting relationships between themselves and their suppliers. Buyers were able to cross reference the information gathered in anonymous pre-audit surveys against other sources to get an accurate and unbiased view of worker wellbeing in their sites. The data enabled buyers to more effectively distribute resources to create a secure working environment and highlight supplier engagement in their responsible sourcing programmes. For suppliers, the survey helped them identify gaps in their workforce management systems and determine how best to improve conditions in their sites.
