Descriptive Analysis Panel Performance
Dragonfly SCI will provide panel performance reports on your descriptive panel data.
Here are the minimum requirements for your data files:
- At least two replications
- At least 8 screened and qualified panel members
- At least 15 descriptive attributes
- At least 3 products
Allow two weeks after file delivery for us to complete the analysis and report. Send your inquiries to Heather at — firstname.lastname@example.org
RedJade licensees that can share their descriptive data files with us through RedJade will receive a 10% discount on the following. This includes a report along with a 60 to a 90-minute conference call to review findings with you and your team.
- One Data Set – $1,800
- Two Data Sets – $2,800
- Three Data Sets – $3,800

QDA Panel Data Quality Review & Next Steps
We also offer intensive, in-person, problem-solving workshops on advanced sensory techniques and descriptive panel management, designed for sensory and consumer science professionals. The Dragonfly SCI team are experts in quantitative descriptive analysis methodology. Hourly consulting rates apply.
Participants will provide pre-work based on their own questions and core challenges, and the lectures and scheduled discussions will be customized to incorporate issues relevant to your unique business challenges and your panels.
Techniques will be demonstrated to solve common problems associated with product development, co-manufacturing, ingredient substitution, new technology, packaging, shelf life, sensory specifications, and quality control, among others.
A few thoughts on descriptive analysis . . .
Descriptive methods are called by many, the most sophisticated tool currently available to measure human perception. The application of descriptive methods continues to grow across all types of product categories.
How do we determine data quality from a trained panel?
Unfortunately, we have seen many sensory professionals shy away from truly understanding panel performance. However, the insight gained from the output files in RedJade provides the richest and most actionable feedback for the sensory department.
As a brief bit of history, panel performance measures were first developed by Stone & Sidel at Stanford Research Institute, before they formed Tragon Corporation. It was their groundbreaking work on QDA in the late 1960s and early 1970s where descriptive analysis grew rapidly. Tragon started selling software for QDA analysis in the late 1970s and it was upgraded over the years in several formats, along with data entry software, plotting software, serving designs, etc., all done to gather, analyze, and report data on sensory analysis. One of Herbert Stone’s favorite quotes is “the proof is in the booth”. What he means by that, is that you must collect descriptive analysis data in a way that is founded in experimental psychology and then apply statistics to understand the variance of products, subjects, and methods – the analysis of variance is our workhorse.
Many of the tests in the Redjade output file today are still based on the QDA method, but it also incorporates other industry experts’ views on descriptive methods, especially as it relates to visualizing panel metrics, which is where we are today. That is good for all of us!
Descriptive data has numerous applications but the role of sensory science is to minimize risks in decision making. It is also used in legal disputes, and sensory claims substantiation, and at some level, you can expect, and be prepared for, a high level of scrutiny on all aspects of your descriptive data.
Let us help you unleash the power of descriptive analysis by teaching you how to utilize the feedback provided by the RedJade output files.
