. A quality control chart technique was tested for feasibility in measuring panelist performance in product profile development. The descriptive sensory score sheet evolved by Filipino trained panelists for fresh‐frozen young coconut meat and water at “malakanin”(7–8 months old coconut fruit) stage was utilized for this study. A comparison of panelist performance in terms of their congruence, within themselves and between each other, in identifying the intensity or presence of an attribute was made. Results indicated that a similar measurement of significant differences could be obtained using both the analysis of variance (ANOVA) approach and the control chart (c.c.) technique. Considering the volume of data to be handled, the c.c. technique appeared to be more manageable than ANOVA. Besides, the c.c. was found by the panelists and the researchers to be more interesting to analyze, easier to apply, to interpret and to use for improvement follow‐through compared to the ANOVA.
