In the era of knowledge economy, the product research and development activities information plays a dominant role, as an indispensable factor of production in improving manufacturing enterprise business process effectiveness and efficiency. In order to improve the quality of product research and development activities information, ProA quality of input output item were defined based on a kind of modeling method of product research and development named activities and its processes (ProA). Furthermore, ProA target quality of input output item configuration mapping were studied, and data importance judge principles for input output item were puts forward, which laid the foundation for activities information decompose step by step.%在知识经济时代,产品研发活动信息作为不可或缺的生产要素在提高制造企业业务流程有效性、高效性以及适应性的过程中都起着支配作用.为了提高产品研发活动信息的质量,以产品研发信息分解过程为导向,基于一种活动及其实现过程(proA)产品研发建模方法,定义了ProA入出项的质.在此基础上,研究了ProA入出项目标质配置映射,提出了ProA入出项数据重要性判断原则,保障产品研发活动信息逐层分解实际可行,为保证产品研发活动信息逐层分解质量奠定了基础.
