ISO 11132:2012给出了监测和评估定量描述面板的总体性能以及每个成员的性能的指导。
一组评估员可以用来评估感官属性的大小。
绩效是衡量一个小组或评估者对被评估产品进行有效属性评估的能力的衡量标准。它可以在给定的时间点进行监控或随着时间的推移进行跟踪。性能包括面板检测,识别和测量属性的能力,以与其他面板或评估者类似的方式使用属性,区分刺激,适当使用比例,重复自己的结果,并从其他面板或评估员。
所规定的方法允许一致性,可重复性,不受偏见的限制,以及区分面板和评估者的监测和评估能力。监测和评估小组成员之间的协议也包括在内。监测和评估可以在一个会话或一段时间内进行。
监控绩效数据使小组负责人能够改进小组和评估员绩效,确定问题和再培训需求,或者确定不能很好地执行的评估员继续参与。
方法具体
ISO 11132:2012 gives guidelines for monitoring and assessing the overall performance of a quantitative descriptive panel and the performance of each member.
A panel of assessors can be used as an instrument to assess the magnitude of sensory attributes.
Performance is the measure of the ability of a panel or an assessor to make valid attribute assessments across the products being evaluated. It can be monitored at a given time point or tracked over time. Performance comprises the ability of a panel to detect, identify, and measure an attribute, use attributes in a similar way to other panels or assessors, discriminate between stimuli, use a scale properly, repeat their own results, and reproduce results from other panels or assessors.
The methods specified allow the consistency, repeatability, freedom from bias and ability to discriminate of panels and assessors to be monitored and assessed. Monitoring and assessment of agreement between panel members is also covered. Monitoring and assessment can be carried out in one session or over time.
Monitoring performance data enables the panel leader to improve panel and assessor performance, to identify issues and retraining needs or to identify assessors who are not performing well enough to continue participating.
The methods specified in ISO 11132:2012 can be used by the panel leader to appraise continuously the performance of panels or individual assessors.
ISO 11132:2012 applies to individuals or panels in training as well as for established panels.
