A short history of sensory evaluation since the first Nordic Sensory Workshop
When the Nordic Sensory Workshop (NSW) was first held in 1987, sensory evaluation data were collected mostly using paper ballots, which necessitated tedious and error-prone data entry. Technicians spent hours with handheld rulers measuring and keying in positions of marked responses on 15-cm line scales. Compusense Inc. was incorporated in 1986 with the goal of computerizing sensory evaluation.
Computerized ballots provided many benefits beyond obviating data transcription. Answers to questions were validated before the next screen was shown. Based on one answer, future questions could be skipped automatically. Automation improved efficiencies and provided high-integrity data.
New methodologies have emerged alongside these technological changes. The once-sharp line between qualitative testing (e.g. open-ended responses) and quantitative testing (e.g. scale responses) is increasingly being blurred, as is the line between sensory evaluation and market research. Today, geographically distributed teams collaborate to create, run, and monitor web-based tests that can be presented in almost any language, anywhere. After completing an online screener, invited panelists who meet criteria and quotas can self-schedule and receive automated reminders. Interim analyses can be shared with research collaborators on demand. Analyses include AI summaries of open-ended comments. Innovation benefits include ease of use, high-throughput testing, actionable decision-making, and oversight of organizational standards.
This short history will recount how sensory evaluation has evolved from the first NSW to present day, emphasizing contributions of Nordic researchers and institutions. After discussing how collaborating and openness to new ideas fosters innovation, this talk will conclude by speculating where sensory evaluation is headed next.
