CNAS/CMA软件测试实验室方法验证的六个方面

正确、有效的软件测试方法是获得可靠软件测试结果的重要前提,也是软件测试实验室申请CNAS/CMA资质时非常重要的一大要素,本文我们就一起来看一下,软件测试实验室方法验证的六个方面,帮助大家快速掌握实验室方法验证。

 

一、方法的选择与有效性

 

1、软件测试实验室在选择测试方法时,可以依据国家标准,个别项目依据行业、地方标准或者国际标准。《系统与软件工程 系统与软件质量要求和评价(SQuaRE 51 品(RUSP)的质量要求和测试细则》GB/T 25000.51-2016是软件测试测试方法的主要依据。

 

2、需要识别方法的现行有效性,将查新工作写入《文件控制程序》中,进行定期查新,确保方法版本的有效性。

 

 

3. cnas/cma软件测试实验室识别方法是否能被操作人员直接使用,当其内容不便理解,规定不够简明或缺少信息、方法中有可选择的步骤时,应编制作业指导书,以确保检验检测人员使用该方法的一致性。

 

二、设备配备与确认

 

 

1.实验室根据标准方法的具体要求配置设备。cnas/cma对软件测试实验室设备方面的要求有:

软件测试实验室

2.设备要做好溯源和期间核查,确保不对检验检测结果产生不良影响。

 

三、场所环境确认

 

 

1.cnas/cma软件测试实验室识别拟开展的标准方法对场所、环境条件的具体要求,并验证本机构配置的场所及其环境条件是否满足要求,并保留验证记录。

 

2. cnas/cma软件测试实验室识别和建立开展标准方法进行检验检测的环境条件监控要求,该要求应以文件的形式(如作业指导书)表示,包括监控项目、监控点、监控频率、监控记录等,以及出现监控结果 异常时的处置方法,并按文件规定予以监控,并保留监控记录。

 

四、人员能力确认

 

 

1.cnas/cma软件测试实验室应通过相应的教育、培训、技能和经验对从事检验检测项目人员的能力进行确认,在此基础上通过授权明确检验检测人员的权利和责任。

2.cnas/cma软件测试实验室应在策划人员培训方案、人员监督方案或制定人员培训计划、人员监督计划时,统筹合理考虑方法验证的需求。实验室实施培训、考核、监督工作,应保存相关培训、考核、人员监督的记录。

3.当培训考核或监督中发现检验检测人员不具备相应能力时,应进一步组织教育培训或对人员岗位进行调整。

4.cnas/cma软件测试实验室应根据能力确认的结果进行岗位授权,岗位授权应具体到检验检测项目的方法。

 

五、样品

 

1.根据抽样程序的要求进行样品的获取。

3.cnas/cma软件测试实验室应建立样品标识系统,确保样品在检验检测过程的唯一性。

4.应确保样品传输与保存的条件满足标准的要求,在进行检测前,对样品的状态信息进行描述。

 

六、检测结果的验证

 

 

1.cnas/cma软件测试实验室在满足1~5条要求后,应使用标准物质、经过检定或校准的具有溯源性的替代设备、重复检测、保存样品的再次检测、参加能力验证或机构之间比对、机构内部比对、盲样检测、实际样品测定等方式,对方法规定的性能指标(如校准曲线、检出限、测定下限、准确度、精密度等)等内容进行验证,并根据方法的要求评价验证过程获取检验检测结果的有效性。

 

2.有条件时,应参加相关部门组织的相应项目的能力验证。

 

3.当比对或能力验证的结果为不满意时,应查找原因,制定措施,重新开展方法验证。
