Since 1978, SigmaValidation has been the only independent, third-party provider of validation services to the marketing research community – and the first to utilize computer technology to track respondent data quality. The foundational program for monitoring and measuring adherence to research standards was created through collaboration between John F. Elrod, founder of Sigma, and the research team at General Foods (now part of Kraft Foods/Mondelēz International). The online version was developed based on demand from the research teams at Kraft/Mondelēz, Unilever, Estee Lauder and Revlon; and based on specific input from their most valued online research partners during Sigma’s 2007 Consortium concerning online research data quality.
For the past 30+ years, Sigma's services have been mandated as part of required research standards by consumer product manufacturers, research suppliers and data collection agencies. Utilized across in-person and online quantitative and qualitative research studies, Sigma helps to ensure the quality of research at its roots – the respondent input level.
